a given landbird species populations may inhabit a variety of habitat
types (habitat generalists) or require a specific habitat type and conditions
(habitat specialists). Many species require a minimum total patch size
of habitat to successfully breed, but "forest-interior obligate"
species will avoid nesting near predator-dense edges and require a minimum
"core area" of habitat (e.g. Wood Thrush). The goal of landscape
ecological modeling is to quantify the characteristics of quality habitat
in terms of cover type, patch size, and pattern of the landscape.
Spatial statistics (FRAGSTATS) can be calculated
at multiple radii surrounding each station using in-house ArcGIS scripts
(IBP Super Tools). The final table of results can be inputted into VizBand
to create species-specific data files of demographic parameters matched
with multiple scale station-specific spatial covariates. Spatial co-variates
for individual cover classes (e.g. forest) include:
