ACE Climate Resilience (Ranks 4 & 5)

The full dataset comes from CA Department of Fish and Wildlife’s Areas of Conservation Emphasis (ACE) project. ACE Terrestrial Climate Change Resilience incorporates statewide information about lands that have a higher probability of serving as refugia for species adapting to climate change. Based on projections from climate models, this dataset indicates the relative likelihood that an area will experience shifts in temperature, precipitation, or other important climate variables that would negatively impact the current array of plants (and by extension animals) that can thrive under those future conditions.

Ranks 4 and 5 are used as an exclusion in the SB 100 Terrestrial Climate Resilience Study Screen. This allows areas of lower climate resilience rank to be considered for exploration of renewable resource technical potential, while keeping areas of higher resilience rank for conservation planning.
