Areas Of Conservation Emphasis (ACE) Version 3: A California Department Of Fish And Wildlife Conservation Analysis Tool

PRESENTED BY MELANIE GOGOL-PROKURAT:

The California Department of Fish and Wildlife (CDFW) Areas of Conservation Emphasis (ACE) project is a non-regulatory tool that brings together the best available map-based data in California to depict biodiversity, significant habitats, connectivity, climate change resilience, and other datasets for use in conservation planning. ACE compiles and analyzes information from multiple CDFW data products, including the California Natural Diversity Database (CNDDB), California Wildlife Habitat Relationships Program (CWHR), the Survey of California Vegetation, as well as other mapped information found in the Biogeographic Information and Observation System (BIOS) to create products that can help inform landscape-scale conservation decisions. The terrestrial data is summarized and displayed in a standardized hexagon (2.5 mi2) grid, and the aquatic data is compiled by HUC12 watershed. All ACE datasets are available in an online map viewer or for download. CDFW has just completed ACE v3, a major revision and update.

ACE Biodiversity metrics are based on 1) species location information from CNDDB and other species survey datasets for 354 rare and/or endemic vertebrate species and subspecies, and 1672 rare and/or endemic plant taxa; and 2) species range or habitat distribution models for 791 common and rare native species of amphibians, birds, fish, mammals, and reptiles, and 183 families of aquatic macroinvertebrates. ACE combines information on species occurrence locations and species habitat distribution models in a standardized way to show the distribution of biodiversity, species richness, rarity, and endemism across the state and in each ecoregion. ACE Significant Habitats brings together information on important habitats such as rare vegetation types, oak woodlands, wetlands, and riparian areas based on vegetation maps and other landcover datasets, as well as information on focal species key habitat areas. ACE Connectivity brings together information on natural intact lands, habitat linkages, and wildlife corridors. ACE Climate Change Resilience brings together information on locations expected to be relatively buffered by climate change impacts. These datasets provide an overview of the conservation elements potentially present at a given location based on best available data, and can be viewed together with State Wildlife Action Plan (SWAP) conservation targets, stressors, and juxtaposition to existing conserved lands in the ACE viewer to provide a broad overview of information important to conservation planning and ecological research. We will describe the data now available in ACE v3, and will present example use-case scenarios.
