Mapping Groundwater Dependent Ecosystems in California (June 2010)

In August 2014 the California legislature passed a three-bill package (SB 1168, AB 1739, and SB 1319) of groundwater reform legislation that is arguably the most significant update of California water policy in several decades. The legislation provides authorities and guidance for local agencies to develop sustainable groundwater management plans and implement the plans to achieve sustainable groundwater conditions in their areas of jurisdiction. Groundwater plays an integral role in sustaining certain types of aquatic, terrestrial and coastal ecosystems, and their associated landscapes. In 2010 TNC published a study in PLoS ONE to illuminate the connection between groundwater and surface ecosystems by identifying and mapping the distribution of groundwater dependent ecosystems (GDEs) in California. The study’s geodata are available for download here.
