Annual Burn Probability represents the likelihood of a wildfire of any intensity occurring at a given location (pixel) in a single fire season. In a complete assessment of...

Large trees are important to forest managers as they have a greater likelihood of survival from fire, provide sources of seed stock, wildlife habitat, and contribute to other...

A key component of forest structure descriptions is the spatial heterogeneity (i.e., tree clumps and gaps), which influences vegetation growth, competition, and succession,...

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...

This is an index of how much less smoke (as defined by PM2.5 emissions) would be produced from a given pixel by burning under moderate fire weather conditions rather than the...

Relative concentration of the Southern California region's Hispanic/Latino population. The variable HISPANIC records all individuals who select Hispanic or Latino in response to...

Large trees are important to forest managers for multiple reasons: they have a greater likelihood of survival from fire; they are an important source of seed stock; they provide...

Dead carbon includes dead and down (litter, duff, fine, coarse, and heavy fuels, including 1000+ hour logs) which are inherently unstable due to prevailing fire and decay...

This metric is an index of the potential smoke production (represented by particulate matter that is 2.5 microns or less in diameter, or PM2.5) that could be emitted for a given...

Summer Steelhead Distribution October 2009 Version This dataset depicts observation-based stream-level geographic distribution of anadromous summer-run steelhead trout,...

This layer represents horizontal cover fraction occupied by tree canopies. Maps community type & fire regime, as well as available habitat for tree-dwelling species.

Tree mortality and other forest damage is detected by annual aerial surveys over forested lands by state and federal agency staff. The primary purpose of the aerial survey is to...

Relative concentration of the Northern California region's Asian American population. The variable ASIANALN records all individuals who select Asian as their SOLE racial...

The original point layer (WildfireOccurrence_CA_1992_2020.shp ) contains a spatial database of wildfires that occurred in the United States from 1992 to 2020. It is the fifth...

This metric, mean percent FRID, is a measure of the extent to which contemporary fires (i.e., since 1908) are burning at frequencies similar to the frequencies that occurred...

These rasters depict the predicted human- and lightning-caused ignition probability for the state of California. Ignition is regulated by complex interactions among climate,...

These data depict 10-meter raster riparian areas for 50-year flood heights for California in 2019.

This data set represents the extent, approximate location, and type of wetlands and deepwater habitats in California. These data delineate the areal extent of wetlands and...

These data identify, in general, the areas where the final revised critical habitat for the Peninsular bighorn sheep ( Ovis canadensis nelsoni ) occurs. This subspecies is only...

Relative concentration of the Sierra Nevada region's Hispanic and/or Black, Indigenous or person of color (HSPBIPOC) population. The variable HSPBIPOC is equivalent to all...
