ACE addresses both terrestrial and aquatic data. The ACE model combines and analyzes terrestrial information in a 2.5 square mile hexagon grid and aquatic information at the HUC12 watershed level across the state to produce a series of maps for use in non-regulatory evaluation of conservation priorities in California. The model addresses as many of CDFWs statewide conservation and recreational mandates as feasible using high quality data sources. High value areas statewide and in each USDA Ecoregion were identified. The ACE maps and data can be viewed in the ACE online map viewer, or downloaded for use in ArcGIS. For more detailed information see https://www.wildlife.ca.gov/Data/Analysis/ACEand https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=24326. 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.

All ACE data layers are limited by the accuracy and scale of the input data. ACE is a compilation of the best available scientific information; however, many of these datasets are not comprehensive across the landscape, may change over time, and should be revised and improved as new data become available. The user accepts sole responsibility for the correct interpretation and use of these data, and agrees not to misrepresent these data. CDFW makes no warranty of any kind regarding these data, express or implied. By downloading these datasets, the user understands that these data are in draft condition and subject to change at any time as new information becomes available. The user will not seek to hold the State or the Department liable under any circumstances for any damages with respect to any claim by the user or any third party on account of or arising from the use of data or maps. CDFW reserves the right to modify or replace these datasets without notification.The ACE maps display biological and recreational values based on available data and constrained by the limitations of the data. The values may be influenced by level of survey effort in a given area. The ACE data represent broad-scale patterns across the landscape, and the value of any single watershed should be interpreted with caution. ACE is a decision-support tool to be used in conjunction with species-specific information and local-scale conservation prioritization analyses.The ACE maps do not replace the need for site-specific evaluation of biological resources and should not be used as the sole measure of conservation priority during planning.

California Department of Fish and Wildlife Rare A species is considered ‘Rare’ for the purposes of ACE, if it is listed 1) under the Federal ESA or California ESA as ‘Threatened’, ‘Endangered’, ‘Candidate Threatened’, or ‘Candidate Endangered’; 2) California Fully-Protected or Species of Special Concern (SSC); for Plants, listed as California ‘Rare’ or Rare Plant Rank 1B or 2B (see https://www.cnps.org/rare-plants/cnps-inventory-of-rare-plants for rare plant rank definitions). California Department of Fish and Wildlife Y indicates species falls under the described criteria Endemic A species is considered endemic if nearly all of its range occurs within California. California Department of Fish and Wildlife Y indicates endemism Climate Vulnerable Many species have undergone a series of formal evaluations by CDFW staff and other experts to determine the likelihood a species’ susceptibility to negative effects on population growth or persistence resulting from climate change. Y means that CDFW has determined the species to be at least moderately likely to experience such negative impacts, either directly or indirectly, as a result of projected changes in climate.

SGCN Species of Greatest Conservation Need as defined n the 2015 State Wildlife Action Plan (SWAP) document. SGCN species include all those which satisfy any of the ‘Rare' field criteria, as well as some species which are climate vulnerable. Not all climate vulnerable species are recognized as SGCN.
