Areas of Land Subsidence in California

In California, land subsidence—mostly from groundwater pumping—was first documented by the USGS in the early 20th century. Completion of State and Federal water projects that bring water from California's wet north to its dry south allowed some groundwater aquifers to recover, and subsidence decreased in these areas. Subsidence continues today, sometimes at high rates of more than 1 foot/year.

National Biogeographic Map

The National Biogeographic Map (NBM) is a project of the Core Science Systems Mission Area. The project’s goal is to provide a platform for analysis of questions about what species are where, how well protected they are, how vulnerable they are to stressors, and what management options will have the greatest benefit for conservation of biodiversity.
