California Areas of Conservation Emphasis (ACE)

Areas of Conservation Emphasis (ACE) is a CDFW effort to gather spatial data on wildlife, vegetation, and habitats from across the state, and then synthesize this information into thematic maps to help inform discussions on the conservation of biodiversity, habitat connectivity, and climate change resiliency. The ACE maps provide a coarse level view of information for conservation planning purposes. The ACE project draws from multiple sources of vetted species occurrence data, as well as predictive species modelling efforts. ACE data products however, do not replace the need for site-specific evaluation of biological resources and should not be used for regulatory purposes.
