Salmonid Population Monitoring Areas - California - CMP [ds3001]

The California Monitoring Plan (CMP) salmonid monitoring areas provides an approximation of the spatial extent of past and present monitoring efforts for coho salmon, Chinook salmon, and steelhead. The areas represent the approximate extent of sampling within sub-basins, watershed areas, or regions. The dataset includes population monitoring areas in California coastal watersheds and some coverage of monitoring areas within the Trinity River and Klamath River basins. This dataset does not include all locations for existing or past monitoring programs. The population metrics summarized within these areas are focused on the viable salmonid population (VSP) key characteristics: abundance, productivity, diversity, and spatial structure. The spatial information is intended to be compatible and link with tabular salmonid population data using the GEO_ID_POL field.
