Description: <div><div>Freshwater Wetlands, Areas of Conservation Emphasis (ACE), version 3.0.</div><div><br /></div><div>The Terrestrial Significant Habitats dataset is one of the four key components of the California Department of Fish and Wildlife’s Areas of Conservation Emphasis (ACE) suite of terrestrial conservation information, along with Terrestrial Biodiversity, Connectivity, and Climate Change Resilience. This data set was developed to support conservation planning efforts by allowing users to spatially evaluate the distribution of terrestrial significant habitats across the landscape. Terrestrial Significant Habitats may include habitats or vegetation types that are the focus of state, national, or locally legislated conservation laws, as well as key habitat areas that are essential to the survival and reproduction of focal wildlife species. The Terrestrial Significant Habitats data set is expected to be used along with other ACE datasets to provide a robust assessment of the presence and relative importance of elements important for biodiversity conservation.</div><div><br /></div><div>The Terrestrial Significant Habitats dataset provides a variety of information on terrestrial habitats synthesized from vegetation and land cover maps. This includes Rare Vegetation Types [ds2722], Oak Woodland Habitat [ds2723], Riparian Habitat [ds2724], Saline Wetlands Habitat [ds2726], and several types of Freshwater Wetlands Habitats [ds2725]. The number of significant habitats in each hexagon is summarized in the Significant Terrestrial Habitat Summary, and a reference to the original vegetation or landcover datasets that map the significant habitat elements is provided for each hexagon. </div></div><div><br /></div>For more information, see the Terrestrial Significant Habitats Factsheet at <a href="https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=150834" target="_blank">https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=150834</a>. 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.
