This National Land Cover Database (NLCD) product represents urban impervious surfaces as a percentage of developed surface over every 30-meter pixel of California, extracted...

Relative concentration of the Sierra Nevada region's American Indian population. The variable AIAN_ALN_AND_MULTIRACE includes BOTH individuals who select American Indian or...

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...

Native species richness is estimated based on high suitability reproductive habitat for a given species. Reproductive habitat is used to represent suitability because it is...

This dataset represents a species habitat distribution map for California Red-legged Frog ( Rana draytonii) within the conterminous United States (CONUS) based on 2001 ground...

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

The metric for time since disturbance ("tsd") was measured as time in years before 2021 since the most recent disturbance of at least 25% canopy cover loss per 30m pixel as...

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...

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

This dataset consists of 5 raster files of the proportion of above ground live biomass in these vegetation type categories: (1) Shrub obligate resprouting; (2) Shrub obligate...

This metric represents cost of potential treatments for the Northern California region and is dependent on predefined treatments or silvicultural prescriptions, which are best...

Relative concentration of the estimated number of people in the Sierra Nevada region that live in a household defined as "low income." There are multiple ways to define low...

Functional groups are sets of species that share life history characteristics that perform particular functions within an ecosystem. The six functional groups are represented...

Runoff is a measure of the water available for storage. It is determined by both the water supply and the demand of the existing vegetation. Annual mean runoff measures the...

This percent canopy cover is intended to be used in combination with the fractal dimension index as a measure of fine-scale heterogeneity.

Relative concentration of the Northern California region's American Indian population. The variable AIANALN records all individuals who select American Indian or Alaska Native...
