Northern California DPU Steelhead Critical Habitat
The Northern California Distinct Population Unit (DPU) of Steelhead Trout ( Oncorhynchus mykiss) is a threatened species. This distinct population segment, or DPS, includes... -
Trail Density
A raster dataset representing density of trails in the Southern California Region. -
Cumulative Shrub Cover Loss
The cumulative loss of shrub cover over a 30-year period (1992-2020). Shrub cover loss reflects fires, harvest/management and dieoff. Only disturbances that are sufficient to... -
Hispanic and or Black, Indigenous or People of Color (Hspbipoc) Population...
Relative concentration of the Northern California region's Hispanic and/or Black, Indigenous or person of color (HSPBIPOC) population. The variable HSPBIPOC is equivalent to all... -
Biomass Residues
This raster layer represents forest residues for the state of California in 2018. It was developed by the Schatz Energy Research Center as part of the C-BREC (California Biomass... -
Fire Ignition Probability Human Cause
These rasters depict the predicted human- and lightning-caused ignition probability for the state of California. Ignition is regulated by complex interactions among climate,... -
Canopy Layer Count
This layer represents the number of distinct vertical canopy layers of trees. Vertical layer count is a proxy for leaf area index, and maps canopy complexity. Since LANDFIRE... -
Northern Spotted Owl Habitat; Topo-Climatic Fire Refugia
Maps that represent the relative probability of fire refugia generated from an empirical model trained on the aggregate history (1985-2019) of wildfire severity, topographical... -
Housing Burden
Housing-Burdened Low-Income Households. Percent of households in a census tract that are both low income (making less than 80% of the HUD Area Median Family Income) and severely... -
Ringtail Cat Suitable Habitat
This layer shows highly suitable habitats for the reproduction and feeding of Ringtail Cat ( Bassariscus astutus ) within the species' range. -
American Indian Land Areas
Lands under the control of federally recognized Tribes. These boundaries have been clipped to the boundary of California so that only the portions of each Tribal area that fall... -
Large Tree Carbon
Large trees in this metric were calculated as the sum of branch and stemwood plus foliage for trees over 20 inches in diameter. This is intended to represent the most stable... -
Density - Snags - 40" or Greater
The number of standing dead trees (snags) on the landscape is important to forest managers; high densities of standing dead trees are known to contribute to extreme fire events... -
Cumulative Tree Cover Loss
The cumulative loss of tree cover over a 30-year period (1992-2020). Tree cover loss reflects fires, harvest/management and dieoff. Only disturbances that are sufficient to... -
