The Landscape Management Network (LMN)
Managing Canada’s forests for the benefit of present and future generations is a complex undertaking.
To achieve this goal we need a better understanding of how the environment, human activities and
natural disturbances interact to shape the country’s forest landscape. Our forests and the environment
do not adhere to the artificial boundaries between provinces and land owners, pointing to the need for
well-informed forest management that includes “the big picture.” As Canada’s major national forest
research organization, the Canadian Forest Service (CFS) has a major role to play in developing tools,
technologies, and data bases to ensure sustainable forest management in Canada. The Landscape
Management Network (LMN) has been established to lead this effort.

Abstract
Canada’s Forest Inventory 1991 (1994 version) is a national compilation of provincial forest resources
inventory data. This national inventory is maintained as a database and it provides information for strategic
decision-making and gives general background information on Canada’s forest resources. This report describes
the database, the source data, how the data were compiled, and provides some direction for its use. Data
summaries and maps are reported in separate companion publications.
The database is normally compiled at five-year intervals, the latest being 1991. The database was extended in
1994 to include data for Quebec and this report describes the database including this addition. The differences
between the 1991 and 1994 versions of the database are described in this report.
The inventory now includes all the major forested zones. The information is a compilation of 48 data sets using
the most current data from the contributing inventories. The data consist of area and wood volume statistics by
up to 12 classifiers. The volume data are available by 17 species groups using pulpwood utilization
specifications. The data are supplemented with information on access, forest section, ecoregions, FAO forest
use classes, policy constraint, productivity, and stocking mixture. The growth is now based on volume and age
data in the inventory. Sawwood volume, tree size-volume relationship and cull have been dropped since 1986.
Successive versions of CanFI (1981, 1986, 1991, 1994) represent the latest compilations at those times, but
differences between them cannot be used as estimates of real change. Some source inventories are the same as
those used in earlier versions of the database. Reinventoried areas may use different classification schemes or
definitions. Not all classifiers and classes are available from every source inventory.

Résumé
L’Inventaire des forêts du Canada 1991 (version 1994) est une compilation nationale des données d’inventaire
des ressources forestières provinciales. À titre de base de données, il fait l’objet de mises à jour. Il fournit
l’information nécessaire à une prise de décision stratégique et donne des renseignements généraux sur les
ressources forestières du Canada. Le présent rapport décrit la base de données, les source de données et les
méthodes de compilation utilisées et donne certaines indications sur son utilisation. Des sommaires de données
et des cartes apparaissent dans d’autres publications complémentaires.
La base de données est habituellement compilée tous les cinq ans. La plus récente compilation remonte à 1991.
Les données du Québec y ont été intégrées en 1994. Le présent rapport décrit donc la base de données ainsi
obtenue et fait état des différences entre les versions de 1991 et de 1994.
L’inventaire couvre maintenant toutes les principales zones forestières. Les renseignements qui y figurent sont
une compilation de 48 ensembles de données établis à partir des données d’inventaire les plus récentes qui nous
ont été fournies. Ce sont en fait des statistiques sur la superficie et le volume de bois classées par attribut (un
maximum de 12 au total). Les données sur le volume sont réparties selon 17 groupes d’essences établis en
regard des critères d’utilisation du bois de pâte. Des renseignements sur l’accès, la section forestière, les
écorégions, les catégories d’utilisation de la forêt de la FAO, les contraintes d’exploitation, la productivité et la
composition du matériel sur pied viennent compléter les données. L’accroissement est maintenant calculé à
partir des données sur le volume et l’âge figurant dans l’inventaire. Depuis 1986, l’Inventaire des forêts du
Canada ne fait plus état du volume de bois de sciage, des rapports dimensions-volume et du bois de rebut.
Les versions successives de l’IFCan (1981, 1986, 1991 et 1994) constituent la somme des meilleurs
renseignements disponibles à l’époque, mais on ne peut pas évaluer les changements réels en se fondant sur les
différences qui existent entre ces inventaires. Certaines sources de données sont les mêmes que celles utilisées
dans des versions précédentes de la base de données. Dans certaines régions, les systèmes de classification ou
les définitions utilisés pour dresser un nouvel inventaire peuvent être différents. De plus, tous les attributs et
toutes les classes ne se retrouvent pas dans chaque source de données.

Preface
The Canadian Forest Service summarizes wood volume and area statistics at five-year intervals, coincident
with Census of Canada reports. This report documents the database that stores these statistics. A companion
report “Canada’s Forest Inventory 1991” by Lowe et al. (1994) presents summaries of the latest inventory
statistics.
Data for Quebec was added to the national inventory data, using source data as of 1994, creating Canada’s
Forest Inventory 1991, 1994 version (CanFI91.V94). Another companion report “Canada’s Forest Inventory
1991: the 1994 version” (Lowe et al. 1995) describes the latest database with a focus on the new Quebec
summaries.
The purpose of this report is to provide background information about and documentation for the current
national forest inventory. Reports giving additional statistics are planned. A service of providing summaries,
data sets, or maps is offered by the Forest Inventory and Analysis Project at the Pacific Forestry Centre,
Victoria, B.C.

1. A Framework for Describing
Canada’s Forest Resources
Background
Canada’s Forest Inventory (CanFI) is prepared by compiling provincial forest resource inventory data into a
common format. In contrast, national statistics in most other countries are carried out on samples from
permanent (or sometimes temporary) plots to standards specified by a coordinating agency. These data are
collected independently of the forest management inventories that are also undertaken in these countries.
The features of the approach used here are that the nationally reported figures will match those reported by the
contributing agencies, and that it is cost effective. There is considerable detail for small geographic areas and
this offers two additional features: Fairly detailed thematic maps can be produced, and the data can be
aggregated and prorated into broad regions.
The forest inventories of 1981 and 1986 and the biomass inventory were part of the Canadian Forest Resource
Data System (CFRDS), a collection of inventories and associated information. While the initial concept of
CFRDS is still valid, the name has been discontinued in favour of CanFI.
Forest inventory statistics are available in allied publications (Lowe et al. 1994, 1995, 1996; Gray 1995). The
forest inventory statistics from this database contribute to the more encompassing forest resource statistics in
the National Forestry Database (Canadian Council of Forest Ministers 1995; Natural Resources Canada 1995,
1996).
A General Description of Canada’s Forest Inventory 1991 (1994 version)
Canada’s Forest Inventory is two separate databases running in parallel. The large size and nature of the
attribute data precludes its inclusion in a geographic information system (GIS). Hence the main data set is
stored in one database and the map data is stored in a separate database.
There is a two-way flow of data between the main database and the GIS. The data are summarized for a map
theme in the main database and passed on to the GIS for mapping. The GIS is used for spatial operations such
as to overlay the boundaries of other larger spatial units, such as forest regions or ecozones, and the results are
passed on to the main database for analytical purposes. Figure 1 describes the principal elements of the CanFI
database.
The forest resource data include a geographic location code which is used to identify the map sheet, township,
Universal Transverse Mercator (UTM) cell, National Topographic Service (NTS) map sheet, etc., to which the
data apply. The GIS describes the location of these same summary units, or cells with the same unique
identifiers. These cells form an irregular grid covering the country. Figures 2 and 3 show the cells used for
CanFI91.V94.
The forest resource information is stored in a relational database as a number of related tables. The data consist
of the geographic location reference (province code and cell identifier), 16 classifiers, and the numerical
attribute information.

The attribute data are stratified by 15 classifiers, as follows:
data source
– inventory type and intensity
ownership
– land owner
status
– control of land for timber harvesting
land class
– description of land (forest, water, etc.)
site quality
– a measure of the relative timber productive capacity of a site
stocking
– description of the density of the forest
cause of disturbance
– reason for nonstocked or unproven stocking
age
– forest age as of the year of information, in 20-year classes
maturity
– forest manager’s opinion based on age and other considerations
forest type
– description of forest canopy as softwood, mixedwood, or hardwood
predominant genus
– description of forest by most abundant genus according to cover type description
year of information
– year in which data were obtained, usually the year of photography
volume type code
– a key to 1 of 3 ways in which volume data of zeroes or missing values codes can
be replaced by average volumes for the same province, region and maturity class.
inventory phase
– key to identify inventories within a province
volume allocation code
– a key to 1 of about 50 ways in which volume data for a species group are
pro-rated into two or more species groups
Each classifier has several classes as described in more detail in Chapter 2. Inventory data gathered for each
cell are summarized into unique combinations of classifiers. There are 48 287 cells with forest inventory data
across Canada, and each of these has, on average, 30 unique combinations of classifiers. These represent
unique forest stands, or, more often, a number of stands with the same unique combination of classifiers.
The numerical attributes are area and volume. The area is expressed to the nearest hectare, and the volume is
the gross merchantable volume. Volume data are stored as cubic metres per hectare to one decimal place.
Volumes are specific for up to 17 species groups, using the pulpwood utilization standards of the source
inventories.
There are seven data sets in addition to the core forest inventory data. These are referred to as auxiliary data.
They confer regional parameters to each cell. The information content of the seven data sets is outlined below.
1)
access:
the presence or absence of any transportation infrastructure (road, rail or forestry water transport) within a
map sheet
2)
ecozone and ecoregion:
a biophysical zone or the smaller regions as defined by the Ecological Stratification Working
Group (1994)
5
3)
forest region and forest section:
a vegetation region or the smaller sections as defined by Rowe (1972)
4)
forest use:
an assessment of goods and services obtained from the forest in seven categories: wood production,
protection, water, grazing (range), hunting, nature conservation, and recreation
5)
policy constraint:
a measure of the availability of wood for harvest by law, regulation, or declared or undeclared
owner policy
6)
productivity:
the long-term growth rate of the forest (mean annual increment at maturity in cubic metres per hectare
per year)
7)
stocking mixture:
percentage of areas described as unproven stocking actually in nonstocked, partially stocked, and fully
stocked categories
The information in these auxiliary data sets applies to areas ranging in size from a map sheet to a province. In
some cases the regions of the auxiliary data have been digitized and processed in the GIS in order to compute
the relationship between cell codes and the auxiliary data region in the main database.
2. Detailed Specifications for Canada’s Forest
Inventory 1991 (1994 version)
The classification of the attributes is described in detail in this chapter. The terms are defined and the numeric
codes are explained. Most of the classifiers have qualitative definitions. Site quality, age class, and year of
information are defined quantitatively. A file layout used for data exchange is described in Appendix I and
Appendix II describes general guidelines for using the codes.
Terms and Definitions
Where possible, the terms and definitions adopted by the Canadian Forest Inventory Committee (Haddon 1988)
are used. If no number is given in brackets at the end of a definition, the definition is specific to this inventory.
The numbers in brackets refer to the following references:

(2) As (1) but modified here.
(3) Society of American Foresters (1958): Forest Terminology. A glossary of technical terms used in forestry.

Cell reference
The source inventories typically compile their data by map sheets or other polygons, referred to in this report as
“cells.” The cell reference code identifies these map polygons, with the most frequently used cell coding
schemes being the Universal Transverse Mercator (UTM) grid designations and the National Topographic
Series (NTS) map codes.
A detailed description of the transformation of provincial cell codes to this national coding scheme, as well as
related information such as dimensions, average areas, and the number of cells, is given in Appendices III
and IV.

Reconnaissance: An exploratory, extensive forest inventory with no detailed estimates obtained (1). A formal
sampling design is generally not used, and no precision estimates are obtained.
Regional: A detailed, extensive forest inventory for planning on a regional or provincial basis (1). Major forest
types are usually mapped, with estimates given for each type. Precision estimates are given for total
inventory volume.
Management: A detailed, intensive forest inventory for management purposes of an area managed as one unit
(1). The forest types are usually mapped in detail with estimates given for each type. Precision estimates
are given for total inventory volume.
Operational: An intensive forest inventory of a small area for harvesting purposes (1). Individual stands are
mapped, with estimates given for each stand.
Ownership
Classes 1 to 3 are owned by crown and classes 4, 5 and 7 are owned privately. For summary purposes

Provincial/territorial: Areas within the jurisdiction of a provincial or territorial government or Northern
Affairs of the Department of Indian and Northern Affairs.
Industrial private: Areas owned by a large corporate industry for commercial forestry purposes.
Nonindustrial private: Areas owned by small corporations or individuals (2).
Municipal: Areas that are the property of a municipality or any other such autonomous government agency (2).
Unspecified private: Areas owned by corporations or individuals at an unknown scale of operation.
Status
The status classifier has two parts that determines the overall management of the resources. The area is either
excluded from timber harvesting by law (“reserved”) or available to some degree for timber harvesting (“non
reserved”). Future versions of CanFI will provide for a more detailed description of reserved and nonreserved
areas by implementing the World Conservation Union’s protected areas classification with additional classes to
accommodate the Canadian situation (Canadian Forest Inventory Committee 19952).

Height at a total age of 50 years
Site quality: A measure of the relative productive capacity of a site for one or more species (1). The two
principal measures are site capability and site index.
Site index: An expression of forest site quality based on the height, at a specified age, of dominant and
codominant trees in a stand (1). These heights, which usually refer to a particular species, are expressed in
metres, and may be grouped into site classes.
Site class: Any interval into which the site index range is divided for purposes of classification and use (1).
Total age: The number of years elapsed since the germination of the seed, or the budding of the sprout or root
sucker (3). Of a forest, stand or forest type, the mean age of the trees comprising it (4). In this inventory,
the total age in an even-aged or regular forest is the average age of dominant trees, from the year in which
the forest was formed, including3 the age of any nursery stock.
Stocking class
Stocking class describes the density of a forest. Values range from nonstocked to fully stocked. Nonstocked
forest land refers to land that is known to have too few trees to form a stand, or where the density of trees is
below a threshold that defines stocked forest.
Unproven stocking refers to forest land with a density that cannot readily be classified. This is disturbed land
known to be productive but where trees were not visible at the time of inventory. For example, there may be a
substantial number of trees regenerating, but they do not show up on aerial photographs.
Unproven stocking areas include a mixture of nonstocked, partially stocked, and fully stocked land. Special
ground surveys are often done independently of the forest inventory to determine the percentage of these
unproven stocking areas that are in reality stocked. Forest managers can also provide estimates based on their
field experience. The “stocking mixture” auxiliary data contains this kind of information, which is collected on
a regional basis, rather than for each cell.
The partially and fully stocked classes reflect the forest manager’s interpretation of crown closure or density.
Partially stocked means that growth is reduced compared to a fully stocked stand. Fully stocked forests have
reasonable growth for extensive management. Fully stocked stands include optimum stocking as well as
overstocking and understocking.

Stocking: A qualitative expression of the adequacy of tree cover on an area, in terms of crown closure, number
of trees, basal area, or volume, in relation to a pre-established norm (1). In this context, tree cover includes
seedlings and saplings, hence the concept carries no connotation of age.
The degree of stocking may be classified as stocked versus nonstocked, or as under, fully, or over stocked.
It may also be expressed as a percentage of the pre-established norm or stocking factor.
Stocked forest land: Land supporting tree growth (1). In this context, trees include seedlings and saplings.
Unquantified stocked: Stocked forest land, with no distinction as to partially or fully stocked.
Fully stocked: Stocked forest land where yield is generally reasonable for extensive management and treatment
is generally not considered. Includes some understocking and overstocking.
Partially stocked: Stocked forest land where yield is significantly reduced and treatment may be considered.
Unproven stocking: Forest land that has had the tree cover removed or killed and where the subsequent degree
of stocking has not been assessed at the time of inventory. There is a lag time after disturbance before a
minimum threshold of trees is reached and stocking can be recognized.
Nonstocked: Forest land capable of producing but generally lacking in tree growth (3).

Age class
Age class is an age interval that applies to the “total age” of the forest at the year of information (not updated to
1994). Twenty-year age classes are used. If there is an offset in the starting year of the age class, the “best fit”
was used. For example, 6 to 25 years was coded as age class 1 (1 to 20 years). The forests are even-aged except
for class -5 which is uneven-aged.
Age class: Any interval into which the age ranges of trees, forests, stands, or forest types is divided for
classification and use. Also the tree, forest, stand, or forest type falling into such an interval (1).

Three kinds of stand ages are possible. Appendix V describes which types of age are used in the various
inventories. The age of the trees comprising the stand are averaged. The three types of stand age are:
breast height: The number of annual growth rings counted at breast height (2). Breast height is 1.30 metres above
ground level (1). On sloping ground, breast height is usually measured on the uphill side of the tree (1).
stump: The number of annual growth rings counted at stump height (2). See Appendix VI for stump heights by
reporting agency.
total: The number of years elapsed since the germination of the seed, or the budding of the sprout or root
sucker (1).
Maturity class
Maturity is based on age, species group, and other conditions defining the harvest age of the wood. Maturity
applies to the stand at the year of information (not the year of reporting). The forests are even-aged except for
class 5 which is uneven-aged.

Regeneration: The renewal of a forest crop by natural or artificial means. Also the new crop so obtained (5).
The new crop is generally less than 1.3 m in height (1). In this context it is the new crop, not the act of
renewal, that is being described. CanFI data may include volume of trees that survived disturbances such
as fire or harvesting.
Immature: In even-aged management, those trees or stands that have grown past the regeneration stage but are
not yet mature.
12
Mature: In even-aged management, those trees or stands that are significantly developed to be harvestable and
that are at or near rotation age (includes overmature trees and stands if an overmature class has not been
recognized) (1).
Overmature: In even-aged management, those trees or stands past the mature stage (1).
Even-aged: A forest, stand, or forest type in which relatively small differences exist between individual trees
(1). To be classified as even-aged, the maximum difference in age permitted it is usually 10 to 20 years; if
the stand will not be harvested until it is 100 to 200 years old, larger differences of up to 25 percent of the
rotation age may be allowed.
Uneven-aged: A forest, stand, or forest type in which intermingling trees differ markedly in age (1). The
minimum difference in age needed for a classification as uneven-aged is usually 10 to 20 years.

Mixedwood: A forest type in which 26 to 75 percent of the canopy is coniferous.
Hardwood: A forest type in which 0 to 25 percent of the canopy is coniferous.
Predominant genus
The predominant genus is defined as the most abundant genus according to the cover type description. This is
usually the first species in the cover type description of the stand in the source inventory.
Other conifers (class 7) include juniper, yellow cypress and western yew. Poplar includes trembling aspen and
other poplars. For a complete description of the species for each predominant genus class, see Appendix VII.
Forest type and predominant genus, when used in combination, describe the forest composition in some detail.
For example “softwood spruce” differs from “mixedwood spruce.” In the former there are 76 to 100 percent
conifers and in the latter there are 26 to 75 percent conifers. In both cases the dominant conifer is spruce.

Year of information
For each record, the year in which the information was obtained by the inventory source. This is usually the
year of photography.
Inventory phase number
For each record, the inventory phase number identifies the source inventory. See Table 1 for an explanation of
the codes.
Volume type code
For each record, the volume type code indicates the source of the volume information, especially where
volumes not available were substituted with provincial or regional values.

Volume allocation code
For each record, the volume allocation code identifies the way volume is prorated. The species groups of some
source inventories are prorated into two or more of the CanFI species groups. The prorating does not change
the sum of tabled volumes. Appendix VIII describes the prorating factors in detail.
14
Numerical Attributes
Area
The area to the nearest hectare.
Volume
The volume data are gross (or net) merchantable volume for pulpwood utilization standards, usually expressed
inside bark. The commercial tree species of Canada are listed in Appendix VII. The volume compilation
procedures used for management inventories are described in Gillis and Edwards (1988).
The species or species groups in the source inventories are standardized to 17 species groups. Prorating
procedures described in Appendix VIII are used on some of the older data sets being carried forward into
CanFI91 and CanFI91.V94 to express the volumes by these 17 species groups. For example, data reported by
“unspecified conifers” and “unspecified broad-leaved species” are now prorated among the other CanFI species
groups.
The volumes are current as of the year of information and are carried in cubic metres per hectare to one decimal
place. Volumes are reported from the database in cubic metres per hectare to one decimal place or in thousands
of cubic metres.
Volume: The amount of wood in a tree, stand, or other specified area, according to some unit of measure or
some standard of use (3).
Utilization Factors
Wood utilization specifications vary within and between provinces, and are appropriate for local industrial
practices at the time of the source inventory. Volumes are normally provided as gross or net merchantable
volume, but the former is preferred. The utilization standards are described in Appendix VI. Sawwood is no
longer carried in the database. The low demand for sawwood statistics warrants discontinuation.
Gross merchantable: Volume of the main stem, excluding stump and top but including defective and decayed
wood, of trees or stands (1).
Net merchantable: Volume of the main stem, excluding stump and top as well as defective and decayed wood,
of trees or stands (1).
Pulpwood: Wood of a size or quality that the reporting jurisdiction generally considers as suitable for pulp,
fibre, chip, commercial chemical, or commercial fuel use, or that is used only in smaller sizes such as
posts or rails.
Two-storied Stands
This type of forest is not recognized as such in the national inventory. Reporting agencies generally report the
overstory. The understorey or a combination of overstorey and understorey may be reported if it is significant
to the forest management.
‘Missing Value’ and ‘Not Applicable’ Codes
‘Missing value’ means that the information is not appropriate for coding. ‘Not applicable’ means that
information is not appropriate for coding. For example, when land class is coded 2 to 7, then classifiers from
“Site class” to “Predominant Genus” do not apply.
15
Missing values and ‘not applicable’ are consistently coded throughout as 8 or -8 and 9 or -9, respectively.
Appendix II gives examples of the use of the missing value and ‘not applicable’ codes.
Auxiliary and Other Related Information
Introduction
The core attributes described above are cell-specific and generally come from the source inventories. The scope
of the database can be extended by including data that pertain to regions or whole provinces or data that pertain
to selected attributes of the core data. Auxiliary data at the region level must be linked to the cell level in order
to be processed with the core attribute data. A GIS is used to determine which cells fall in which regions.
This chapter describes the auxiliary files in general.
Access
The access data describe the presence or absence of a transportation infrastructure within the area covered by a
map sheet. This does not necessarily imply that all the forest resources in the map sheet are either accessible or
inaccessible. The concept was first described in Inventory of forest biomass in Canada (Bonnor 1985). Unlike
the other auxiliary files, this file has data at the cell level.
The access files were developed for use with CanFI86 and required additional GIS analyses to apply to
CanFI91 and CanFI91.V94. The GIS procedure passed the access data from one version of the cells to the next
version of the cells. The access attribute data were updated for CanFI91 and CanFI91.V94 and then reviewed
with the cooperation of the provinces and territories. The current trends throughout Canada are that many rail
lines are being closed and transport on waterways continues to lose its importance.
There were some minor changes in the interpretation of the access classes. Access was earlier reported for any
presence of a transportation route for every cell. For pragmatic reasons this guideline is eased somewhat.
Larger cells (more than 10 000 km2) in which the access is available for only a very small percentage of the cell
are described as not accessed.
Access by winter roads is reported if it is the normal local practice, especially over large areas in the north.
Similarly, water access is reported if it is the normal local practice.
Accessed: The presence of a transportation route (road, rail, or water) within, or on the border of a CanFI cell.
No implication of economic accessibility for timber harvesting is intended.
Not accessible: Indicates the absence of a transportation corridor.
Road: Road access is reported for the highest class of transportation whether other classes occur or not.
Paved –
all paved roads, regardless of whether they are main or secondary roads.
Gravel – all-weather roads that are gravel-surfaced or constructed in suitable soils to allow yearround transportation. Permanent access or mainline roads with a life span of 20 years or
more are included in this category.
Earth –
roads that are not surfaced with gravel and may have a life span of one to ten years.
Winter – roads that can only be used in the winter months.
Rail: Rail lines used for freight.
Water: All salt and freshwater routes that could be used for log transport.

Cull and tree size-volume relationships
These two auxiliary files were introduced in the 1986 version of the database and have since been discontinued
because the expected client interest did not materialize.
Ecozones and ecoregions, forest regions and forest sections
Ecological units provide a framework for reporting status and trends at varying levels of generality. Two crossCanada ecological schemes are used with CanFI. Terrestial ecozones and ecoregions are described by the
Ecological Stratification Working Group (1994). The terrestial ecozones are “macro-order” ecosystems
characterized by macro-climatic regimes, plant formations, major soil zones and first-order subcontinental
landforms. Terrestial ecoregions are nested within each of the 15 ecozones and there is a total of 194
ecoregions.
The forest regions and forest sections have been in use since 1937 and are most recently described by Rowe
(1972). The forest regions are primarily forest units originally conceived as stable, climatically controlled
formations characterized by certain tree species. There are 10 forest regions as well as Grassland and Arctic
and Alpine Tundra. Within each region are nested forest sections; there is a total of 90 sections. The forest
sections are areas with a consistent presence of certain tree species and a different character than other sections
in a region.
The GIS was used to associate each cell with an ecoregion and with a forest section. A somewhat different
approach was used in each case when two or more regions occurred in one cell. With the forest sections, the
cell was assigned to the section with the largest area. With the ecoregions, prorating factors were determined
giving the percentage of the cell in each of the Ecoregions.
17
The forest section files were developed for use with CanFI86 and required additional GIS analyses of Quebec
to apply to CanFI91 and CanFI91.V94. The ecoregion file was developed for CanFI91 and, similarly, required
GIS analysis of Quebec to apply to CanFI91.V94.
Canada’s forest resources are described by ecozone and ecoregion in Lowe et al. (1996) and by forest region
and section in Gray (1995). The ecozone scheme divides Canada into zones defined on a biophysical basis and
cannot be readily equated with, for example, the more familiar boreal forest.
Importance of forest use
Forest lands are used for many purposes in addition to timber harvesting. The database has been extended in the
1991 version to consider these other functions: protection, water, grazing (range), hunting, nature conservation,
and recreation. Lowe et al. (1994), Appendix 2, Table 17.2, p 61 to 62, gives percentages of forest categories
subject to internationally defined levels of use (low, medium, or high). These factors are applied to Canada’s
forests in Lowe et al. (1994) (Chapter 12). The categories and classes of forest use are defined below, and in
further detail in The forest resources of the ECE region (Europe, the USSR, North America) (United Nations
1985). The forest use file was developed for CanFI91 and applied without change to CanFI91.V94.
Forest use – this is an early attempt to assess the importance of several kinds of goods and services obtained
from the forest. The seven forest use functions are wood production, protection, water, grazing
(range), hunting, nature conservation, and recreation.
Separate estimates are made for public (i.e., Crown) and private lands. These two ownership
categories are subdivided into timber-productive and timber-unproductive forest. Twenty-eight
estimates are made for each combination of forest use (7), ownership (2), and timber productivity (2).
Each estimate presents the percentage of the forest area that is rated as high, medium, or low for that
use, with a total of 100%.
Wood production – the long-term (50–100 years) average annual harvest yields per hectare. High – more than
Medium. Medium – 1 to 3 m3 ha-1 yr-1. Low – less than Medium.
Protection – based on the criteria of risk, the value to protect, and the protective capacity of the forest. High –
all the criteria are high and the protective function has a higher priority than other uses. Medium –
significant protective functions (e.g., erosion) but the system is sufficiently stable to allow most
forestry operations (which may require modification). Low – less than Medium.
Water – based on the conservation, protection, or promotion of water supply. High – area designated for water
supply, other uses restricted. Medium – water collection areas must be protected, other uses not
restricted. Low – area not currently used for water collection or supply.
Grazing (range) – based on absolute production rather than importance for the local population. High – greater
than Medium. Medium – the food production for grazing animals during a vegetation period contains
500 to less than 1000 megacalories per hectare (1000 megacalories equals 4200 megajoules, and is
equivalent to about 175 kg of milk or a slaughtered net weight of 20 kg.) Low – less than Medium.
Hunting (and trapping) – based on the game population and its attractiveness and economic value for hunting.
High – game population and annual capture rates are high in absolute terms. One species can be
considered separately, or species that are close to but below the minimum can be combined. Medium –
not high, although the area is attractive for hunting, and hunting occurs regularly. Low – very low
game populations or hunting and trapping are not attractive.
Nature conservation – based on the degree of regulation, with formal or voluntary regulation required for a
high or medium rating. High – the object under conservation has national or international interest, and
is protected over other land uses. Medium – either the objects protected are uncommon in the region
but not rare or endangered in the country, or a particular type of forest is being protected. Low – less
than medium, but general conservation regulations may exist that apply to all forests (e.g., streamside
reserves).
18
Recreation – based on special qualities of the resource and proximity to population centers. High – areas close
to population centers and frequently visited (120 or more recreational visitor hours per hectare per
year). Close means within walking distance (5 km) or that attractive sites are within easy reach of day
trips by car (30 km). More distant areas may have very special qualities and arrangements to attract
visitors. Medium – not high or low. Low – forest rarely visited for recreation, and walking access is
not allowed or is difficult (over 5 km from vehicle parking), and the area contains no objects of
particular attraction.
Policy constraint on harvest
The “reserved” forests legally exclude timber harvesting. “Nonreserved” forests, however, are not all available
for timber harvest. They are still subject to constraints for aesthetic or environmental reasons as prescribed by
the province or territory. There may be buffers along streams and around lakes, zones to protect special fish and
wildlife concerns (such as deer wintering yards and fish spawning beds), and zones to avoid areas subject to
erosion. These buffers or zones constrain harvesting by regulation or by policy.
Another factor, particularly with private lands, is the owner’s preference. Many nonindustrial owners prefer not
to harvest their wood. This can be a declared or undeclared owner policy and this can vary through time. Some
provinces have conducted opinion polls to determine owner preferences for forest harvesting, particularly in
provinces where there are more private lands.
The policy constraint factors describe only one aspect of the net availability of wood. Additional factors can
still apply. First, the wood must be physically present in the size, amount, and species required. Second, it must
be economically feasible to harvest, transport, and process the wood. Third, additional regulations may provide
for the planning of a long-term wood supply, as well as economic and social stability.
The policy constraint auxiliary data provides factors to net down the area of timber productive forest to the area
unconstrained for harvesting. Estimates were provided as percentages or in broad classes, at the province level
or by region, and for all ownerships or combinations of owners (see below).
The 1986 version of CanFI also provided for a special case, forest lands that can be harvested once and then
will no longer contribute to sustained-yield management. This applies, for example, to forest lands designated
for settlement and clearing for agricultural purposes. This class is not used in CanFI91.V94.
The policy constraint classes and codes are listed below. Appendix IX describes the general availability of this
data. Policy constraint is applied to the inventory in Lowe et al. (1994) (Chapter 12, p 19).

Productivity
Estimates of forest productivity initially used in CanFI86 were estimates provided by the source agencies; if
none were available, the default values from Bickerstaff et al. (1981) were used. A new approach was later
developed for CanFI86 and the same growth rates have then been adopted without change in CanFI91 and
CanFI91.V94. These growth rates were calculated from the inventories rather than from external sources. The
principal advantage of determining the growth rates using an empirical method is that the growth rates are
consistent with and complementary to both the classification attributes and the volume attributes of the core
data. The type of growth estimates determined provide long-term average increases in the volume of the stands
surviving to what the source inventories define as mature.
Chapter 11 of Lowe et al. (1994) describes the calculation of these growth rates. For each of some 1800 strata,
the pulpwood volume of the mature forest is divided by age4. The growth rates are expressed in cubic metres
per hectare per year. Appendix X describes the strata. The strata are defined by province or territory, forest
section, site class, predominant genus (and if predominant genus is not available, by forest type), and include
the coniferous and broad-leaved ratios of the mature forests. The growth rates of these strata are then combined
with the core attribute data to report the growth for any selection of stocked timber productive forest.
Stocking factors
The stocking mixture factors introduced in the 1986 version of the database received continued interest and
minor modifications in 1991. This type of auxiliary data expands and recharacterizes the “unproven stocking”
lands. These are areas of disturbed timber-productive forest lands subject to fire, harvesting, or pest damage
and where the source inventories did not provide further details at the time of the inventory. Forest regeneration
cannot be detected from the aerial photographs (typically 1:20 000 scale) used in management inventories. The
source agencies often handle site establishment with other information systems.
The stocking factors describe the proportions of the “unproven stocking” land that is determined to be either
“nonstocked” (less than 1 m high) or in the earliest stages of “stocked.” The “nonstocked” area is also added to
“age class 0.” The portion determined to be “stocked” is added to the “unquantified stocked,” “regeneration,”
and the “age class 1 to 20” classes. The information is provided by knowledgeable foresters and estimated at
the provincial level by cause of disturbance (Bunce 1989)5. These factors are reported in Lowe et al. (1994)

(Appendix I, Tables 17.1). The adjustment is reported only at the national level since the estimates are provided
at the provincial level (see Lowe et al. 1994, Appendix I, Tables 16.5 and 16.6, pages 33 to 35) and applied to
all subsequent tables describing the area of stocked timber productive forest (Lowe et al. 1994, Tables 16.10,
16.11, 16.13, 16.29, and 16.30).
Biomass and other data
Other auxiliary information can be combined with the Canada’s Forest Inventory as needs dictate and resources
allow. One project underway relates volumes in CanFI to forest biomass components by regionalized and
species-group-specific biomass equations. Components of the 1985 biomass database (Bonnor 1985) have been
updated where appropriate.
Summary of Changes Since CanFI86 was Described
Changes to the way the data were classified and processed were intentionally minimized in the CanFI91 and the
CanFI91.V94 databases. However, as described in the preceding chapter, three new attribute fields were added
to CanFI91 to improve data tracking: pulpwood volume type, phase and volume allocation.
Two auxiliary files, tree size-volume and cull have been dropped. Four auxiliary files have been added since
the last version of this document (Gray and Nietmann 1989): access; forest regions and sections; ecozones and
ecoregions; and forest use. Productivity has been substantially reworked since it was first documented in 1986.
Access, forest regions, and productivity were first applied to CanFI86.
3. The Source Inventories
General
Canada’s forest inventory 1991 (1994 version) is a compilation of 48 inventories. Table 1 describes the 48
contributing inventories and Figure 4 shows their geographic extent.
The data come from provincial or federal inventories, and in some cases from joint federal-provincial
inventories. For CanFI91 the database was a summary of forest inventories in the source agencies’ computer
databases available as of Dec. 31, 1990. For CanFI91.V94, the Quebec data were incorporated as of Dec. 31,
1993 while the remaining data were unchanged. Table 1 summarizes the situation for CanFI91.V94. In many
cases the source agencies had the same inventories as in 1986 or earlier. Twenty-six of the 48 inventories (51
percent by area) in CanFI91.V94 were the same as in CanFI86 except for minor changes to accommodate the
somewhat different file structures of CanFI91.V94. Eleven of the 48 contributing inventories (26 percent by
area) to CanFI91.V94 can be traced back to the first version of the database, CanFI81.
Year of Origin
The actual year of origin of the data pre dates the 1991 or 1994 years of acquisition. The source agencies
require about three years of processing from the year of the photography to the year the data are in their
database. Their data are also collected on an ongoing basis, so that areas are revisited every 10 to 20 years. The
reinventory cycle can be continuous (that is, a certain percentage is inventoried annually) or the inventory may
be conducted over a short period of time and the entire procedure repeated periodically (Gillis and Leckie 1993;
Leckie and Gillis 1995).

Source inventories
Generally the areas of Canada with higher forestry activity have management inventories with renewal cycles
of 10 to 15 years. Accordingly, the average age of data from these sources will be about eight to ten years.
Areas with a lower level of forestry activity, often northern areas with trees that are marginally merchantable,
generally have reconnaissance inventories and discontinuous reinventory cycles. These reconnaissance
inventories may be older, as in the Northwest Territories, or they may be recently compiled for this version of
CanFI (Table 2).
The year of information (or origin) is attached to every record in the database and is typically the year of the
aerial photography. The average year of information of 1980.3 for CanFI91.V94 (from Table 1) is therefore
reasonable and consistent with the production processes involved.
British Columbia has begun a program to keep its inventories current between re-inventories. This program
combines observation and modeling for the major factors of change. The information provided by British
Columbia for CanFI91 was all updated to late 1990.
The predominant age6 of the year of photography of the source inventories is shown in Figure 5. The older
inventories tend to be in areas of lower activity and priority for forest management.
Whole Census Inventories
Most of the source inventories (93.3 percent of the inventoried area) are based on aerial photography7 and
provide essentially a 100 percent coverage of the area. Some source agencies do not include some federal or
native lands.
Sample-based Inventories
Some of the reconnaissance inventories (6.7 percent of the inventoried area) are based on samples (Table 2),
using photo plots. About 23.1 million ha (3.6 percent of the inventoried area) is based on photo plots.

Surveys to Complete the Inventory of the Forest Zone
General
For CanFI91 the remaining gaps were filled, so no major areas of merchantable forest land remain without at
least some data. New surveys were conducted for CanFI in Ontario and Manitoba up to the boundary
describing “significant forest cover.” New or updated inventories in Alberta and Saskatchewan completed the
inventory of the forest zone. All that now remains outside the inventory is stunted and sparse trees north of the
tree line and widely scattered stands in the prairie zone.
Ontario and Manitoba
The two new inventories conducted were: 1) an area of 16.4 million ha in northern Ontario; and 2) a narrow
zone of 3.8 million ha in northern Manitoba. The southern limit of these inventories was defined by the
existing provincial inventories. The northern limit was the edge of “significant forest cover” as defined by a
map (at a scale of 1:7.5 million) using AVHRR satellite imagery8 from a satellite mapping project (Energy,
Mines and Resources Canada and Forestry Canada 1993).
The boundary lines for these areas were fitted to the relevant provincial map sheets: the 10 km × 10 km UTM9
cells in Ontario, and the 6 mi × 6 mi townships of Manitoba. The areas were subdivided by the forest section
boundaries (Rowe 1972). Manitoba had three polygons, two for forest section B.27 and one for B.22a. Ontario
had four polygons, two for B.5, and one for each of B.22a, and B.8.
A one-phase sampling design was employed, which is to say there was no ground sampling. Volume and age
estimates were not made. A sampling intensity of 84 plots gave an estimate of the stocked timber productive
forest to a maximum confidence interval of 5% (P 0.7) for the study area in each province. There were 99 and
102 photo plots for Ontario and Manitoba, respectively, using 1:50 000 to 1:60 000 scale air photos10. The
surveys were undertaken by the Canadian Forest Service. The provincial forest agencies assisted by providing
the ownership and status codes of the photo plots.
Alberta
The Alberta southern reconnaissance inventory was recalculated using the data from CanFI86, adjusted for
photo plots that now were inside the coverages of provincial inventories. Adjacent new inventories by the
Alberta forest service reduced the CanFI91 southern reconnaissance inventory from 6.899 million ha to 5.508
million ha. An Alberta northern reconnaissance inventory, in the Peace River area, of 1.16 million ha was
added to CanFI91 using data provided by the province.
Saskatchewan
The Saskatchewan 1950 reconnaissance inventory in CanFI91 replaced and expanded upon the northern
reconnaissance inventory from CanFI86. The 1950 reconnaissance inventory covers 14.16 million ha (14 map
sheets) and is based on data provided by the province. Adjustments were made to separate the Lake Athabasca
water (class 7) from other water (class 6) in three map sheets. This new data set replaced the CanFI86
reconnaissance inventory described in Gillis (1988).

Summary
The location of the above reconnaissance inventories are shown on Figure 4. The forest resources of these
remote areas are significant. The stocked timber-productive forests in the northern Ontario and northern
Manitoba reconnaissance inventories are 3.985 million ha and 0.3 million ha, respectively.
The completion of the inventory to the edge of continuous forest makes obsolete the earlier estimates of the
area beyond the inventory (Forestry Canada 1988, Table 1). The improved estimates of the forests in these
reconnaissance inventories reduce the forested area of Canada from those earlier estimates.
Supplementary Data Added by CFS–PNFI
Water bodies larger than 4000 km2 have been added to CanFI91. These were for: 1) the St. Lawrence River to
the official freshwater mouth of the river11 (CanFI phase QC-5); 2) the Canadian portion of the Great Lakes
and Lake of the Woods in Ontario (CanFI phase ON-6); and 3) several large lakes in Manitoba (CanFI phase
MB-3). In addition, changes were made for large lakes, previously uninventoried areas, and other
miscellaneous changes in Alberta (CanFI phase AB-10) and the Northwest Territories (CanFI phase NT-2).
Federal and Native Lands
Most of the territorial, native, and federal lands data from CanFI81 were carried forward into CanFI91.V94.
There is new data for about half of the Yukon Territory. Generally, the time and resources were not available to
pursue the individual inventories of the many hundreds of federal and native properties.
The inventories of federal and native lands are ongoing and are generally local matters that are not organized in
the same way as provincial and territorial inventories. The preferred procedure is that federal agencies provide
copies of their data to the provincial agency. If a province includes federal lands within its own inventories then
data from those lands will have been included in CanFI91.V94. Federal or native lands without any inventory
available from the provincial agency are often treated as “missing values.”
In some cases CanFI91.V94 may also include data from the Federal Forest Inventory (Fedinv81). This
inventory is treated in this report as a single source inventory but is itself a composite of a number of
inventories. Much of this Fedinv81 data came from Department of Environment biophysical surveys of the
1960s and 1970s, Department of National Defense resource surveys, and Department of Fisheries and Forestry
reconnaissance surveys of Indian reserves from the 1960s.
Classifiers Available from the Core Data
All inventories have as minimum common denominators data source, ownership, status, land class, and forest
type. Most inventories provide information on cause of disturbance, maturity class, and pulpwood volumes by
species groups or genera. Nine of the 48 inventories have a full complement of information. There is a
significant increase in the number of classifiers used since CanFI86, especially in management-level
inventories. For example, in CanFI86 only one inventory had the full complement of attribute information.
Older inventories tend to have more missing values as they are reconnaissance-level inventories which by their
nature include fewer classifiers. Tables 3 and 4 list the inventories and the attributes they carry.

Forest Activity Zones
The introduction of forest activity zones will improve reporting on forestry statistics by enabling a
discrimination between areas where forestry is more or less active. A zone of active forest management can be
estimated from the database as areas where “management” inventories12 are used, where the land is
predominantly nonreserved13, and where there is access to the forest. The remaining areas not included in this
category would have some constraint to forest management or would be a low priority for forestry purposes.
Reconnaissance or satellite data sources are presumed to be a good indication that forest management is either
extensive in scope or passive. Figure 6 delimits the forest by activity zones.

4. Data Preparation
Collaboration with Source Agencies
A prerequisite for combining a number of different inventories is a standardized terminology and Canada-wide
coding specifications. The provinces and the Canadian Forest Service have collaborated in defining forestry
terms in Canada (Haddon 1988). The specifications for the national inventory were developed with the
cooperation of the Canadian Forest Inventory Committee. Tables (referred to here as conversion tables)
describe the link between the source inventories and national inventory specifications. The conversion tables
were constructed to provide the best possible fit of the source inventory to national specifications. Refer to our
web site at http://www.pfc.cfs.nrcan.gc.ca/landscape/inventory/ to view and obtain copies of these conversion
tables.
Recoding Source Inventory Data to a Standard Format
The contributing agencies processed the data at cost for the Canadian Forest Service. The principal task for the
contributing agencies was recoding their inventories to the national specifications. Other major tasks included
providing information to update the GIS index to their cells and providing data for certain auxiliary files.
The Petawawa National Forestry Institute (PNFI) provided software for 1) recoding individual provincial
inventories, if requested, 2) assuring quality of data, 3) aggregating stands, 4) standardizing the volumes to
uniformly grouped species and replacing “missing value” volumes with regional averages, and 5) aggregating
the data to higher level data files. PNFI designed and maintained the attribute and spatial databases, and
established procedures and software for reporting tabular summaries and maps from the database. The exercise
also included a change in computer software and database design.
The regional establishments of the Canadian Forest Service provided liaison with the provincial forest services.
In CanFI86, these regional establishments had played a major role in recoding and aggregating the provincial
inventories. In CanFI91 and CanFI91.V94 this was done by provincial forest services or by PNFI.
Stand-level source data typically consist of about 500 stands per map sheet. The data were reduced to fewer
records per map sheet by combining stands with identical classifiers. The areas are summed and the per hectare
volumes are weighted by the respective areas of the joined stands. After the stands were joined the average
number of “stands” with a unique classifier was reduced to about 30 per map sheet. Figure 7 illustrates the
concepts of moving from individual stands within a map sheet to aggregated “stands” for a map sheet and the
shift in the scale of resolution from 1:20 000 to 1:20 000 000. The stand-level data can be mapped directly,
whereas the multiple records per cell of CanFI require processing to “map summaries,” such as the calculation
of the predominant class or weighted means, before the data can be mapped.

Quality Assurance
After the source data were recoded to national specifications, they were checked for the following anomalies:
•
blank records
•
invalid characters
•
range errors (data numbers out of range)
•
inconsistent coding (codes for certain classifiers are related)
•
missing cells
•
cell areas out of range (area of a cell is not within some specified range of the cell area in a reference list,
referred to as the “master cell list”)
•
volume of a record (in cubic metres per hectare) exceeding the maximum of the expected volume
•
unexpected species (a species outside its expected biological range)
•
volume of a record reported as zero when it should be reported as “missing data” (a stand was immature
or mature).
The data were checked before aggregation. The quality checked and aggregated data set was then delivered to
PNFI, where a second quality check was carried out. If any errors occurred, the data were sent back for
correction. In order that all data could be mapped and all cells would have data, the spatial database was
checked at PNFI by comparing the master cell list against the GIS cells.
Final Steps by CFS–PNFI
Volume data were missing in the source inventories for about 7.4 percent of the records. The volume data
coded as “missing” were replaced with averages compiled by province, forest section and maturity class. In the
few cases where data were not available for those combinations, provincial averages by maturity class were
used.
When data on the species specific volumes were restricted to either two (coniferous and broad-leaved) or 11
(genus-level) species groups, the volume was allocated to the 17 detailed species groups (see Appendix I) by
using ratios of species volumes reported for the region of observation or a region similar to it. Appendix VIII
lists the information sources used to provide the prorating ratios for this procedure.
In order to decrease processing time for anticipated higher-level queries against the database, additional
aggregations were done on the data set. One aggregation dropped rarely used classifiers. Other aggregations
summarized the data by forest sections, ecoregions and by province. These aggregations reduced the number of
records to about 10 percent and decreased computer processing times for many routine queries. With the
change to a relational database, Ingres, additional refinements further decreased computer processing time.
37
5. Using the Data
Conversion Tables
Conversion tables serve as a record of the recoding process. Users of the inventory can use these tables to
understand and assess the national data in the context of the original source data.
Uninventoried Areas
CanFI91.V94 now includes inventories for northern Ontario, northern Manitoba, northeastern Saskatchewan,
and northwestern Alberta; coverage of Canada’s merchantable forest zone is now complete. There are minor
exceptions locally, but, for the most part, all significant areas are covered. Uninventoried areas, particularly
smaller parcels of federal and native lands, may occur.
“Missing Value”
There was provision for a “missing value” class for every classifier. Tables 3 and 4 describe for each source
inventory the percentage of the total area with available classifiers. Missing data situations may introduce some
bias. Northern areas are characterized by poorer forest resources and a lower priority for forest management.
The reconnaissance inventories in these areas tend to have fewer classifiers. For example, most northern
inventories do not have age class or predominant genus classes. The users of tabular summaries are advised of
these cases through the reporting of statistics labeled “unclassified.” Thematic maps minimize any distortion by
showing only the classified portions of the data, and, when appropriate, may report that the information was
entirely missing.
The conversion tables can also be checked to determine which classes were used. Some classes within a
classifier may not be used. For example, many inventories did not use “uneven-aged” as a maturity class or a
“pest” as a cause of disturbance class.
The stocking data are either classed as “unquantified stocked” or separated into “partially” or “fully stocked.”
This treatment allowed for missing data for stocking density.
Adjustments for Recently Stocked Stands
The “unproven stocking” class includes a large percentage of timber productive forest that should be reassigned
to the youngest age and maturity classes. Accordingly, the age class 1–20, and regeneration classes are
underestimated until these adjustments are made. These adjustments are discussed in Chapter 2 under the
heading “Stocking factors.” The adjustment applied to Canada in Lowe et al. (1994) assigns 7.465 million ha of
“unproven stocking” to each of “unquantified stocked” (see Table 16.5 of Lowe et al.), “age class 1 to 20,” and
“regeneration.” The remaining 11.197 million ha of “unproven stocking” lands were assigned to “nonstocked”
(Table 16.7 of Lowe et al.) or “age class 0” (Table 16.6 of Lowe et al.).
Grouped Classifiers
Some classifiers include grouped data which may result in either underestimates or overestimates for affected
classes. For age and maturity, some source inventories have cases where values are grouped at the top end of a
series14. For age, this only occurs in the Newfoundland Management inventory, and the Nova Scotia 3P
inventory for age 81 years and older and age 101 years and older, respectively.
14
also referred to as right-censored data
38
In several inventories the “mature” class also includes “overmature”. In these cases “mature” is overestimated
and “overmature” is underestimated. The extent of this bias depends on the definition of mature used in the
source inventory and whether stands are biologically capable of reaching an overmature state.
Grouping data at the lower end of a series of classifiers occurs when the “immature” class includes
“regeneration.” A special case of grouped data at the top end of a series lead to a modification of CanFI age
classes. Age classes for British Columbia “141 to 250” and “250 and greater” are processed as CanFI age
classes “15” and “20.”
The above situations of grouped data were generally believed not to warrant adjustments. The impact depends
on how the data are used and how statistics such as means are computed.
One instance of grouped data was adjusted for CanFI91.V94 by PNFI. Similar such procedures may be used in
future versions of CanFI where warranted. The upper age class for Quebec (101 years and older) was prorated
into four age classes (60% to 101–120 years, 25% to 121–140 years, 10% to 141–160 years, 5% to 161 years
and older).
Grouped Species in the Volume Data
The grouping of volume into coniferous, spruce, pine, poplar, birch and other combinations as described in the
conversion tables resulted in significant underestimates and overestimates in the other species groups. Such
groupings of species are common in reconnaissance inventories and older inventories. Recent inventories for
areas with most intensive forest management activity have more detailed species information.
Procedures were used for CanFI91 and CanFI91.V94 to prorate these grouped species and effectively eliminate
any underestimates and overestimates by species. The process is described in Chapter 4.
Different Utilization Specifications for Volume
There are no uniform standards for pulpwood volumes in Canada. This reflects the independence of the source
inventories which were designed to suit the regional variance in tree size and mill requirements. The
specifications for growth also match those of the source agency, since they were derived from the same volume
data. The different standards result in differences in the volume and growth figures between source inventories.
For example, minimum diameters at breast height range from 7 to 17.5 cm. One province’s figures (British
Columbia) are provided in net volumes rather than gross volumes. The utilization specifications are described
in detail in Appendix VI.
The significance of these different utilization specifications is uncertain. To date it has been accepted by clients
of the database as an incidental situation for which no adjustment is readily available or apparently necessary.
Spatial Resolution
The descriptive attributes of the original source inventories have been entirely retained. No stand which had
unique attributes in the national scheme has been modified or averaged. Furthermore, the cells are, for the most
part, covered with a 100 percent census. Accordingly, any map summaries of descriptive attributes and area
statistics, even at scales of 1:30 000 000, retain the same meaning and detail as the original detailed
management inventories.
Mapped displays of volume are regarded as a strength of CanFI, although somewhat less robust than area
statistics. Most management inventories compile volume tables on a regional level. CanFI displays these
volume data at the cell level for areas averaging about 10 000 ha.
39
Using Auxiliary Data
Auxiliary data are usually provided at the region or province level and by selected classifiers. While
calculations are done in the database at the cell level, the spatial resolution of the results is at the level of the
auxiliary data. Similarly, analyses by classifiers should be limited to the classifiers available in the auxiliary
data. The auxiliary data work well at the intended summary levels.
Other Comments
CanFI benefits from the demanding standards of its component management inventories. It also benefits from
being a large aggregation which balances out many irregularities and variations in the component inventories.

Appendix II. Coding requirements for CanFI core attribute data
This appendix describes the coding combinations used for the major types of records in the
inventory. Under normal coding conditions records can be coded with a specific class or be
coded as "missing value." The "not applicable" code and zero are used in particular situations.
Table II-1 summarizes the permitted coding combinations.
Source, ownership, status, and land class
These classifiers are never coded as "not applicable." Source would have been coded as
"missing value" only in an unusual situation and such a situation did not occur.
Stocking class and cause of disturbance
If the land is stocked timber-productive forest then the cause of disturbance is "not
applicable." If the timber-productive forest is 'nonstocked' or 'unproven stocking' then the
cause of disturbance has normal coding and the remaining fields (except year of
information, phase, and area) are coded as "not applicable."
Nonforest classes
For the nonforest classes, land class is described as class 2 to 7 and the remaining fields
(except year of information, phase, and area) are coded as "not applicable."
Uninventoried areas
Uninventoried areas were entered into the database when their occurence was recognized
by either the source agency or by the CanFI staff, however, they are not consistently
reported. Land class code 8 designates such an uninventoried area. In these cases,
ownership and status may be available, or may be missing. Source is usually "other
inventory." The remaining fields (except year of information, phase, and area) are coded as
"missing value." The year of information is the year the data were prepared, say, 91 if done
in 1991.
Year of information
Year of information ranges from 44 to 91 and is never coded as "not applicable."
Inventory phase and area
Inventory phase and area are always positive values and are never coded as zero, "missing
value," or "not applicable."
Volume type and volume allocation
Volume type and volume allocation data (describing the volume attribute data) are coded
zero or certain positive values. They are coded as "not applicable" when the volume
attribute data is coded "not applicable." They may be temporarily coded as "missing value"
or zero until the processing of volume by species is completed.
Species
Species are coded normally for stocked timber-productive forest. Normal coding is zero,
any positive volume, and "missing value." A zero value is used when the merchantable
46
volume is too small to measure; or when the species is absent in the forest stand; or the
species is outside its biological range. For example, yellow birch, a tree of southern Ontario
and eastwards is coded zero in western Canada and in northern parts of eastern Canada
(where this coding is reasonable to implement).
All the species are coded "not applicable" when volume is not expected, such as for
nonforest conditions. For uninventoried areas each species is coded as either "missing
value" or zero, depending whether the species is inside or outside its biological range,
respectively.

1 Use a species volume of zero if the species is outside its biological range, for example, yellow birch is limited to southern parts of eastern Canada and should be
coded as zero meaning "not occurring" in western Canada and where reasonable in northern parts of eastern Canada.

The top diameter is measured outside the bark for Newfoundland only.
c
Each tree in Nova Scotia inventory is individually measured for optimum stump height. The stump height described is the
average.
d
In B.C. the volume figures were updated to 1991 (increased by adding growth accummulated since the year of photography)
using the Variable Density Yield Program (VDYP).
dbh =
Minimum diameter at breast height (1.30 m above ground level) outside the bark. This is the threshold dbh rather than
a class midpoint.
FIZ =
Forest Invemtory Zone
top dbh = top diameter inside bark.
