Weed Data Collection Manual
SECTION TWO TECHNICAL DATA DESCRIPTION
Introduction
Section two of the Weed Data Collection Manual provides technical data descriptions, including metadata, data dictionary and comprehensive weed species tables,
and is intended to assist weed data managers. The information meets data standards obligations, informs weed database design, and assists software developers
and power users to create their own electronic tools for the collection of weed data.
The metadata section describes characteristics of the NT weed dataset as a whole and contains a Metadata ID.
The Data Dictionary describes each of the values for the data attributes, data type, set values, and design notes related to that attribute. Unless indicated, the
attribute descriptions are the same for ALL geometry types. (ie points, polylines or polygons). The specified values must be entered into the datasets exactly as
written. Text values should be written using proper case. eg, write Yes. Do not write YES (upper case) or yes (lower case).
Attribute type
Details
Core attributes
These are the minimum requirements to establish a reliable, valid record with useful information for operational and strategic
weed planning.
Recommended attributes
The Weed Management Branch recommends collection of this data to improve and evaluate the effectiveness of control effort
and weed impacts over time.
Optional attributes
Optional attributes are useful for operational planning within an organisation, for particular project requirements or for property
scale weed planning. Records submitted to the Weed Management Branch do not require optional attributes but they will be
retained by the Branch if submitted.
The weed species listing contains a comprehensive list of Northern Territory weeds and should be taken as a guide to how to represent weed species names
internally within weed databases.

(polygons)
The majority of the Northern Territory Weeds Dataset
is point data, derived from GPS locations, containing
attributes that describe weeds species in the Northern
Territory. These datasets are used to assist the
Weed Management Branch and the Northern
Territory Government identify existing weed
infestation locations and new weed incursions, to
monitor control measures and report to various
funding bodies. Point data location coordinates are
stored using decimal degrees.
The data is regularly updated and managed by the
Spatial Data Manager of the Weed Management
Branch.

This field should best describe the treatment applied to the weed point area on the day the record is taken.
When TREATMENT is used with optional fields SURFACTANT, CHEM_TRADE, CHEM_CONC, and ADJUVANTS the attribute

causes the table to fail 3 normal formal form due to transitive dependency ie: ‘attribute is dependent on the key and only on the key’.
The impact of the associated anomalies is considered minor in the context of the weeds database as records are not typically deleted
or modified in regular usage.
Administrators are advised to check field TREATMENT against the value of these fields for addition anomalies before adding records,
and to periodically check TREATMENT against these field values for the entire dataset. Application level controls can be used to
reduce the number of addition anomalies.

Recommended Attributes
These fields are not core. Data administrators can decide if this field is relevant to their organisation’s needs and may choose not to include it in their data sets. The

Notes
Care must be taken with project names to ensure they are entered consistently for each record, apply application level controls where
possible.
PROJECT
Actual project names may contain punctuation characters which cause difficulties for GIS or database processing, users should be
made aware of these restrictions and application level controls applied where possible.
This field may cause update, addition and deletion data anomalies, apply application level controls where possible.
Database design
st
Actual project names frequently contain compounds of species, activity and date which causes the table to fail 1 normal formal form
ie: ‘attribute contains only atomic values, and the value of each attribute contains only a single value from that domain’.
A strong user case exists for associating weed records with the project that enabled their recording. The convenience of seeing project
information on the same row as the weed record without the complexity of joined tables is cited as the rationale for this anomaly.
Organisations with a strong information processing capacity should consider use of separation of tables to remove this anomaly.
Users specifically required sufficient field length to store full actual project names in their entirety, organisations with less complex
project requirements may shorten this field to more conventional lengths.

When the site has been visibly impacted by past treatment methods record ‘Yes’.
If a treatment was known to be applied but its impact is not visibly noticeable then record ‘No’.
If uncertain whether poor plant condition is the result of past treatment, or is a consequence of water stress, dieback, or other adverse
environmental factors then record ‘Unknown’. Also record ‘Unknown’ if the site is not assessable due to fire, flooding or other
disturbance.
Further details of the impact of control can be recorded in optional fields TREAT_MON and SITE_COND.
For mechanical treatments such as slashing, record ‘Yes’ only while the treatment continues to mitigate the impact of the weed. Once
the weed has regrown to nuisance level it should be recorded as ‘No’.
For fire impacts, only record ‘Yes’ where the impact is a result of weed management prescribed fire, record ‘No’ for wildfire or other
burning practices such as fuel reduction.
Do not record the impact of treatments applied on the date of the record (today) in this field.
Database design
This field replaces TREAT_WHEN field in the previous standard and corrects the 2 normal form failure where the TREAT_WHEN
value was not dependent on the entire compound key. This loosely translates to the concept that each individual weed record must
refer to a specific instance of a weed in one time and place.

Notes
Comments are an unreliable way to store information in the medium or long term as they are difficult or impossible to search or
aggregate, and may become detached from the record in data entry or processing. Attribute fields, file notes or other comment
management systems should be used in preference.
Memo fields are an efficient data structure for storing text, the length expands or contracts to accommodate only the text entered.
Some systems, notably ESRI shapefiles, do not support Memo structures and a Text field of length 150 should be used as a

Be mindful of the impact of past treatments when assessing the present density of the weed in the field DENS_CAT.
Database design
Field PAST_TREAT when used with optional attributes TREAT_MON causes the table to fail 3 normal formal form due to transitive
dependency ie: ‘attribute is dependent on the key and only on the key’.
The impact of the associated anomalies is considered minor in the context of the weeds database as records are not typically deleted
or modified in regular usage.
Administrators are advised to check field TREAT_MON for addition anomalies before adding records, and to periodically check or
recalculate TREAT_MON for the entire dataset. Application level controls can be used to reduce the number of addition anomalies.

Northern Territory Weed Species List
Common names are often used during the weed data collection process. Please
use the same exact spelling and ‘leading capital’ format used in this list, as many
data processing tools are case sensitive. For example - write Athel pine, not Athel
Pine.
Alert species, significant threat to the NT: Alert species are likely to cause
significant harm if they should enter and become established the NT. Some alert
species have been previously found in the NT and managed for eradication, or are
established in regions close to the NT. Not all alert species are declared, those
which are declared are also listed under the relevant declaration class. Authorities
should be contacted urgently if alert species are found or suspected.
Declared weeds - schedule of classes
A
B
C
To be eradicated
Growth and spread to be controlled
Not to be introduced to the Territory
All Class A and Class B weeds are also Class C weeds.
Dominant common names: Where a one member of a genus is overwhelmingly
represented as a weed the common name for that species may refer to the genus
only.
Examples:
Name Convention Notes
Punctuation: Punctuation has been removed from species and common names,
with the exception of the ‘dash’ character usage described below. This is because
many punctuation characters cause problems for spatial or database processing.
Hyptis suaveolens
Mimosa pigra
Cryptostegia grandiflora
Salvinia molesta
Stylosanthes guianensis
Common name groupings: Where a genus has a common name
eg: Cylindropuntia, the common name for the group is written first followed by the
common name specific to the species, or the species name itself if such a
common name doesn’t exist. For example, Cylindropuntia imbricata would be
rope cactus – devils rope, and Cylindropuntia rosea would be Rope cactus –
rosea. Grouping common names enables them to be found easily on a list.
Example:
For more information about these species, refer to the NT Declared List,
www.nt.gov.au/weeds
Weeds of National Significance (WoNS): WoNS weeds have been identified as
a national priority, information and resources are often available to assist in
identification and management of WoNS species.
Hyptis
Mimosa
Rubber vine
Salvinia
Stylo
Rope cactus - fulgida
Rope cactus - devils rope
Rope cactus - rosea
Rope cactus sp
Cylindropuntia fulgida
Cylindropuntia imbricata
Cylindropuntia rosea
Cylindropuntia sp
Use of sp and spp: The botanical abbreviation ‘sp’ is used when the plant is
identified by genus only and the species remains unknown. For weed data
collection purposes ‘sp’ represents only those species of primary weed concern
where those species may be difficult to distinguish. For example, Cenchrus sp
refers only to annual or perennial mission grass, rather than any other Cenchrus
species. The use of ‘sp’ is restricted to weed species which are likely be confused.
The abbreviation ‘spp’ represents a collective group of species from the same
genus and is only used for weeds declared as a species collective, for example
Salix spp.
Example:
Mission grass sp refers to Mission grass – perennial OR Mission
grass - annual (either not both)
Subspecies: Subspecies are not listed unless the subspecies forms part of a
weed declaration class, they are listed by the abbreviation ‘ssp’. Weeds should
not be recorded as sp, spp or ssp unless it is listed as such in the following weed
list.
