Aquatic Species List - ACE [ds2740]

Aquatic Species List, Areas of Conservation Emphasis (ACE), version 3.0.

The Aquatic Biodiversity Summary is a compilation of the best available information on aquatic species biodiversity in California, including aquatic amphibians, fish, aquatic invertebrates, and aquatic reptiles, for the California Department of Fish and Wildlife (CDFW) Areas of Conservation Emphasis Project (ACE). It is one component, together with Terrestrial Biodiversity, of overall species biodiversity in California. The aquatic biodiversity summary combines the three measures of biodiversity developed for ACE into a single metric: 1) aquatic native species richness, which represents overall native diversity of all species in the state, both common and rare; 2) aquatic rare species richness, which represents diversity of rare species; and, 3) aquatic irreplaceability, which is a weighted measure of rarity and endemism. The data can be used to view patterns of overall species diversity, and identify areas of highest biodiversity across the state, taking into account common, rare, and rare endemic species. Users can view a list of species that contribute to the biodiversity measures for each watershed.

The aquatic biodiversity summary is a sum of values normalized by taxonomic group, so that areas of highest diversity for each taxonomic group contribute equally to the final map.
