Modeling the Effects of Ecosystem Fragmentation and Restoration: Management Models for Mobile Animals.
Abstract
Objectives of the proposed research include advances in theoretical and empirical ecology and the development of practical management models to guide landscape planning and habitat management in areas where operational objectives coincide with significant wildlife and natural area values. The proposed field research will elucidate relationships between landscape composition and the abundances of sensitive, threatened, and endangered species. Key questions include: What are the life history characteristics that determine the type and magnitude of a species' sensitivity to fragmentation and, more specifically, habitat edges and landscape boundaries; how do microclimatic factors change when a large block of suitable habitat is fragmented into several smaller blocks; Can the biologically significant aspects of habitat type and landscape composition be determined form remotely sensed data products? Modeling efforts will build on connections between life history characteristics and the responses of mobile animals to habitat fragmentation and restoration. A 2nd phase of field research will test model predictions and refine the conceptual approach. Use of the validated landscape-scale models in management situations will allow management personnel to estimate and compare the effects of alternative management activities on species of special concern. By simulating the results of proposed activities, managers will be able to select activities that minimize or avoid altogether the negative impacts on sensitive species.
