Delta Habitat Opportunities - Assessing Risks with Climate Change
Track: Environmental Management
Author(s): Dave Hansen, Robert Twiss

The California Delta is a key component of the largest estuary on the west coast and is the conduit for the water supply for much of California. Both the Delta environment and the water supply system are in crisis and are at high risk. The area is dynamic. Land use change is active on the periphery of the Delta. Sea level rise and expected changes in precipitation patterns increase the uncertainty of what habitat conditions will be over time. Of interest are existing terrestrial and aquatic habitats and potential areas or corridors that may have similar conditions in the future. ArcGIS provides a variety of spatial analysis and spatial statistics tools for modeling terrestrial habitats for this area. This should assist in reducing risks for both the environmental and water supply systems.
