Summary

Terrestrial Significant Habitats Summary, Areas of Conservation Emphasis (ACE), version 3.0. The Terrestrial Significant Habitats dataset is one of the four key components of the California Department of Fish and Wildlifes 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. 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.

Description

For more information, see the Terrestrial Significant Habitats Factsheet at https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=150834 .

The California Department of Fish and Wildlifes (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 .

The ACE data is subject to certain assumptions and limitations that must be considered in any use or application of the data. 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 hexagon 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. No statement or dataset shall by itself be considered an official response from a state agency regarding impacts to wildlife resulting from a management action subject to the California Environmental Quality Act (CEQA).
