Vernal Pool Hydroregime Surfaces for the Central Valley of California

Vernal pools are ephemeral wetlands formed in small, topographic depressions throughout the Central Valley of California. Ecological processes in these wetlands are dominated by their hydrologic conditions, collectively described as their hydrologic regime. This includes the timing and duration of flooding and patterns of inter-annual variability (e.g., fraction of years with flooding suitable for reproduction of a certain species of concern). This dataset provides a preliminary look at geographic patterns in seven important hydroregime variables.
