Abstract
Species distribution along a territory is a function of different environmental variables that changes in space and time. In this communication we use GIS based information from different sources and at different scales (1x1 km2 and 10x10 km2) for elaborating habitat suitability models of two forest raptors species (Buteo buteo and Accipiter gentilis) along a north-south gradient in Cataluña. The area of study has an extent of 7000 km2. Forest raptors species presence/absence data on 679 1x1 km2 grid cells of the Catalan Breeding Bird Atlas, and Spanish Forest Map at a scale 1:50,000 are the main information sources. Logistic regression methods have been essayed for comparison across different scales. Unexpectedly, preliminary results show no relation between variables like land use type or diversity of habitats and raptors presence at 1x 1 km2 , and this relationship is only significant for Buteo buteo at 10 x 10 km2 scale.
