The overall objective of this project was the development of a verifiable, spatially extensible Geographic Information System model of vegetation, soils, land use, topography, and nitrogen and phosphorus dynamics within the Olawa River watershed inwestern Poland. We have completed the overall GIS for the watershed, including production of the first comprehensive, digital soil and land use maps for this area. Other research objectives completed were: publication of a new GIS-based biodiversity conservation plan, integration of LANDSAT Thematic Mapper data into the Olawa GIS, and development of a riverine macrophyte GIS for the Olawa watershed. These activities resulted in the training of ten Polish scientist in addition to the Principal Investigators, publication of eight refereed papers, and presentations at four national or international meetings.
