Matchett, E.L., and Fleskes, J.P., 2017, Data for projected impacts of climate, urbanization, water management, and wetland restoration on waterbird habitat in California’s Central Valley: U.S. Geological Survey data release,


The dataset summarizes areas of Central Valley wetland and cropland waterbird habitats available for each of 17 projected scenarios by each month (August–December and following January–March). The dataset also includes relatively recent (year 2005) area of existing habitat (i.e., “existing area”) for comparison with habitat areas based on scenarios. Cropland habitats are defined as winter-flooded rice, unplowed dry rice, winter-flooded corn, unplowed dry corn, and other winter-flooded cropland (in Tulare basin). Wetlands are defined as summer-irrigated seasonal wetland, seasonal wetland that is not summer-irrigated, and semipermanent wetland (combines semipermanent and permanent wetland types). Thus, data on availability of waterbird [...]

Project research was funded to evaluate potential future impacts of changes in climate, urbanization, and water supply management on waterbird habitats. These data provide results information that is referenced in a corresponding scientific article composed for publication (accepted upon revision). The data corresponds with figure 4 of Matchett and Fleskes (accepted upon revision; Plos One). References to the data currently pertain to waterbirds, but may be applied to other species that depend on some or all of the same habitats as waterbirds. In the future, this data may be used in comparison with output of other scenarios developed and analyzed by researchers.
