Modeling the Potential Distribution of Forests with a GIs

One of the objectives of forestry planning is to set out criteria for a territory's reforestation oriented towards the reduction of fragmentation and the conservation of biodiversity. This objective may be attained by establishing for each forest type appropriate suitability models, which express the suitability of each point of the territory for the growth of each forest formation. The suitability models may be constructed by utilizing spatial analysis methods, which relate the current presencelabsence of forest type to a set of environmental variables. On the basis of maps of diverse environmental variables, we elaborated suitability models for the forests present in the study area using logistic regression and weights-of-evidence techniques integrated into a geographic information system. Combining the suitability models for eac
