    Terrestrial Rare Mammal Richness - ACE [ds2712]

    Metadata Updated: July 24, 2025

    For more information, see the Rare Species Richness Factsheet at https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=150814. The user can view a list of species potentially present in each hexagon in the ACE online map viewer https://apps.wildlife.ca.gov/ace/. Note that the names of some rare species, such as those at risk of over-collection, have been suppressed from the list of species names per hexagon, but are still included in the species counts. The California Department of Fish and Wildlife’s (CDFW) Areas of Conservation Emphasis (ACE) is a compilation and analysis of the best-available statewide spatial information in California on biodiversity, rarity and endemism, harvested species, significant habitats, connectivity and wildlife movement, climate vulnerability, climate refugia, and other relevant data (e.g., other conservation priorities such as those identified in the State Wildlife Action Plan (SWAP), stressors, land ownership). 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/ACE and https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=24326.
