ACE 3 Working Group and ACE 3 Development Team, California Department of Fish and Wildlife. Scripting and GIS data product development: Ryan Hill, Sandra Hill, and Melanie Gogol-Prokurat. ACE 3 conceptual model and source data development: Melanie Gogol-Prokurat, Sandra Hill, Diane Mastalir, Kristi Cripe, Dan Applebee, Janet Brewster, Kristina White, Patrick McIntyre, Todd Keeler-Wolf, Lisa Ohara, Steve Goldman, Peter Ode, Whitney Albright, Ryan Hill, and Karen Miner. Multiple datasets were compiled and analyzed in the development of ACE, including but not limited to California Wildlife Habitat Relationship (CWHR) species ranges and distribution models, California Natural Diversity Database (CNDDB) and other Biogeographic Information and Observation System (BIOS) rare species occurrence data, and Vegetation Classification and Mapping Program (VegCAMP) vegetation maps/landcover data. A full list of the datasets included in the ACE analysis is included in the technical report: https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=24326.

Use limitations

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).
