Description
Summary:The detrimental effects of habitat fragmentation on animal populations are widely documented (Whitcomb et al. 1981 Robinson et al. 1995) however the development of practical tools to predict the effects of fragmentation and design appropriate mitigation efforts has progressed slowly (Saunders et al 1991 Wiens 1995). The Effective Area Model (EAM) is designed to provide a predictive tool to link field and remotely sensed data in a landscape model that permits comparison of the impacts of alternative land use strategies on animal populations (Sisk and Margules I 993 Sisk et al. 1997). The model uses quantitative measures of species-specific edge effects to weight habitat quality within a particular patch based on distance from the edge. The model then generates predictions of the distributions of organisms resources or environmental conditions in heterogeneous landscapes. The original document contains color images.
