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 Significant Habitats Summary, Areas of Conservation Emphasis (ACE), version 3.0. The Significant Aquatic Habitats dataset is one of the components of the California Department of Fish and Wildlife’s (CDFW) Areas of Conservation Emphasis (ACE) suite of aquatic conservation information. The Significant Aquatic Habitats dataset provides a variety of information on aquatic habitats to help determine the likelihood of the presence of habitat or vegetation that are the focus of state, national, or locally legislated conservation laws, as well as significant habitat areas essential to the survival of specific species of conservation concern. Aquatic habitat data are synthesized from information on vegetation and land cover, and species-specific habitat information. The number of significant habitats in a watershed is summarized in the Significant Aquatic Habitat Summary, and a reference to the original vegetation, landcover, or other datasets that map the significant habitat elements is provided for each watershed. The Aquatic 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.

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.

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.
