This project seeks to systemize the detection and assessment of situations in which specific forest sites assume special significance by virtue of their placement in particular landscape patterns. These situations arise as a result of spatial structure that transcends the concept of forest as land supporting growth of stands of trees. Conventional forest ecology and management address such occurrences only in general terms, leaving detection and assessment as being substantially subjective. The spatial technology needed to achieve this purpose also has broad spectrum relevance in other aspects of planning and management for land and water resources while contributing quantitative substance to the field of landscape ecology. Gap Analysis This project has the dual goals of conducting a regional vertebrate biodiversity analysis for Pennsylvania and developing a framework in advanced information technologies whereby the implications of land-use decisions and trends for biological diversity in Pennsylvania can be evaluated systematically and objectively. The knowledge base and analytical capability arising from the project should serve to guide both public policy and efforts of nongovernmental organizations concerned with conservation of biological diversity. The work is an integral part of the nationwide GAP ANALYSIS effort and will extend technology for applying the results of GAP analysis in other states. Multiscale Statistical Approach to Critical-Area Analysis and modeling of Watersheds and Landscapes Public agencies and corporate landholders are developing and maintaining major environmental databases for computerized mapping and analysis. The project focuses on development of objective and efficient methods for determining patterns of spatial variation from such databases -- particularly relating to water resources and landscape ecology -- and for making pattern comparisons between databases having different levels of detail. These capabilities will help managers to choose appropriate spatial resolution of data, improve districting of watersheds, and locate areas needing remedial attention. PHASE-Based Broad-Area Landscape Change Analysis This work exploits
the spatial structure of landscapes through image compression by hyperclustering
to detect patterns of environmental change. Spatially-based expressions
of landscape change are derived from remotely sensed imagery obtained
through the Landsat Pathfinder program for North American Land Characterization
(NALC).
