The U.S. Environmental Protection Agency hosted a press availability on June 2, 2011, to highlight a national effort to assess the health of the nation’s wetlands, and an opportunity to provide input on proposed changes to how the government protects wetlands. The media event was held at the Stone Lakes National Wildlife Refuge in Elk Grove, California, where scientists simultaneously sampled nearby wetlands as part of the National Wetlands Condition Assessment (NWCA).

Press Release

The NWCA is a collaboration between EPA and its state, tribal, and federal partners representing the first-ever national field survey on the health of the nation’s wetlands. More than 1,000 sites across the country—including 43 in California—are being surveyed to assess indicators of wetland health, including water quality and flow, vegetation, and soils. NCWA sampling locations during the next two months will include wetlands in the following California counties: San Mateo, San Diego, Orange, Solano, Contra Costa, Ventura, Marin, Monterey, Humboldt, San Joaquin, Inyo, Merced, and Mendocino.
