Objective:

This project seeks to manage a large variety of GIS and biodiversity databases. This allows for a number of unique analyses that can be closely coupled with other modeling and ecosystem projects to help determine such things as species composition, habitat availability, population estimates, risks of toxic substances to wildlife, and non-point source loading to rivers.

Approach:

The Core's computer center has developed into a National center for GIS and environmental database design and dissemination, and has recently been named the California - Southwest Regional Node of the National Biological Information Infrastructure (one of the five regional federal data centers established by Congress last session). Work done in the core has proven of considerable value to a number of agencies, and the Core has attracted over 60 additional grants and contracts to extend Center work, including over a dozen from EPA Region 9. In the biodiversity arena, recent projects include developing data standards for international exchange of information on invasive species for the Inter-Americas Biodiversity Information Network (the biological information exchange mechanism under the Summit of the Americas) and the North American Biodiversity Information Network (the corresponding mechanism under NAFTA), agreements with the California Department of Transportation to evaluate the impacts of long-term roadbuilding and urbanization on rare habitats and threatened and endangered species. We also are the major state center for mapping occurrences of rare fish and amphibians, and continue to maintain on-line databases of species records in California State Parks, U. S. National Parks, and UNESCO Biosphere Reserves worldwide.

Geographic Information System (GIS). A sophisticated GIS facility, supporting 11 graduate students, with 14 GIS-specialist staff, over 30 ArcInfo workstations, and a variety of peripheral equipment, is now well established. The facility has about 150 statewide GIS layers of environmental themes, especially land forms, land use, biodiversity and water quality, mostly online, and has become the most active California university GIS program in interagency GIS development (under the aegis of the California Biodiversity Council, the California Geographic Information Association, and the National Biological Information Infrastructure) . The Center is the major developer and repository in the state for the National Hydrography Database (the successor to the EPA River Reach Files), the EPA Waterbody system, and other systems used by EPA and collaborating state agencies in managing water quality, water supply, biodiversity issues, and ecological risk assessment. Many of the techniques developed by the Center and its collaborators in the Department of Fish and Game have now been adopted for national implementation.

Clean Water Act Reports. The Center is continuing a project with EPA Region IX and the State Water Resources Control Board to update, modernize, and disseminate the water body reports required under Sections 303(d) and 305(b) of the Clean Water Act for California. Software to help Regional Water Quality Control Boards prepare 303(d) and TMDL designations were installed last year, and we continue to provide updates, training, and technical support. In the last year, we completed and created web sites to help agencies and the interested public to identify, couple and map existing restoration activities, Best Management Practices, monitoring activities along impaired waterways. We are continuing a cooperative programs with Region 9, the California Department of Forestry, the California Department of Transportation and the SWRCB to make their non-point-source and stormwater assessment data interoperable.

World Wide Web. The Core facility's World Wide Web server disseminates data and model results to collaborators, managers, and the general public. The Internet activities have been incorporated into a number of electronic data access initiatives, including CERES in California, and the National Biological Information Infrastructure and the Government Information Locator Service at the national level, and the Smithsonian and the UNESCO Man and the Biosphere program internationally. It has been a leader in developing interactive mapping technologies, and now experience 10-20,000 downloads per day.

Expected Results:

As a result of the variety of GIS and biodiversity databases managed by the Core, we have the ability to do a number of unique analyses, which will be closely coupled with and complementary to the other Core models and the ecosystem projects.

Investigators are constructing new models, using somewhat similar statistical approaches, to predict the species composition and critical habitats for fish, amphibians, and some indicator invertebrates, in rivers and streams that have not been surveyed. The growing databases of aquatic and riparian species occurrences (some 220,000 records to date) will allow investigators to both estimate the parameters of an aquatic "Species Analyst" model and to test its accuracy. (Preliminary studies in three northern California watersheds suggest that the accuracy of pilot analyses exceeds 80%).
