The amount and quality of natural resources available for terrestrial and aquatic wildlife habitats are expected to decrease throughout the world in areas that are intensively managed for urban and agricultural uses. Changes in climate and management of increasingly limited water supplies may further impact water resources essential for sustaining habitats. In this report, we document adapting a Water Evaluation and Planning (WEAP) system model for the Central Valley of California. We demonstrate using this adapted model (WEAP-CVwh) to evaluate impacts produced from plausible future scenarios on agricultural and wetland habitats used by waterbirds and other wildlife. Processed output from WEAP-CVwh indicated varying...
Metrics used to evaluate scenario impacts and success of proposed conservation actions were provided in datasets for specific Central Valley basins. Metrics included the amount of projected available habitat area (and loss of area) across years, and resulting impacts of habitat reduction on goal waterbird populations. Metrics evaluating success of proposed habitat conservation actions primarily focused on adequacy of food supplies to support wintering waterfowl at CVJV-goal population levels. Metrics were provided for each scenario evaluated in WEAP-CVwh.
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
