Mapping of recreational value of forests in
Lorraine
Objective
Based on a survey on recreational use of
forest in Lorraine carried out in 2010 :
To map the marginal willingness-to-pay
(WTP) of changes in quality and access to
forests in Lorraine by the population living
in Lorraine
•
“Standard approach”, however :
•
High resolution spatial data
•
Taking into account the choice of travel mode
Spatial resolution:
Municipalities: 2337
Data
Web-based survey 2010 : 526 forest
visitors (described in Abildtrup et al.
2015 JEEP)
Data on: number of visits, which forest
visited most often, travel mode, sociodemographics, Choice experiment
Forest units: 5268
GIS database
Location of residence
Forest characteristics
Distance from residence to forest
Modelling approch : Random utility model
Utility (forest j) = f(attributes of forest j)+ random term

Number visits to forests
•
Average number of visits per year: 26
•
Number of visits depend on distance to and quality of local forests as well
as characteristics of the household.
•
Trip demand model to assess changes in number of visits by chaning
acces or quality of forests
