Aquatic Species Richness

Aquatic native species richness is a measure of species biodiversity, and is one measurement used to describe the distribution of overall species biodiversity in California for the California Department of Fish and Wildlife (CDFW) Areas of Conservation Emphasis Project (ACE). Native species richness represents a count of the total number of native aquatic species potentially present in each watershed based on species range and distribution information. The data can be used to view patterns of species diversity, and to identify areas of highest native richness across the state. The species count consists of four taxonomic groups '€“ fish, aquatic invertebrates, aquatic amphibians, and aquatic reptiles.

ACE addresses both terrestrial and aquatic data.
