Landscape Ecological Modeling

For 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:
