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...

The seral stages are categories that represent the developmental progression of forest ecosystems from initial establishment or following a stand replacing event (e.g., high...

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

This data set represents the digital range map of Joshua Tree ( Yucca brevifolia ) in western North America. It is only found in the Southern California Region of California.

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...

This data layer depicts lands designated as critical habitat under section 4 of the Endangered Species Act for the Marbled Murrelet in California. Critical habitat is the...

This dataset represents the "Observed Distribution" for coho salmon in California by using observations made only between 1990 and the present (November 2022). It was developed...

The Band-Tailed pigeon is a species of tribal value to California indigenous peoples and has been identified as a focal species for the CLPM project. This metric identifies the...

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...

Biomass estimates for shrubland-dominated ecosystems in southern California have, to date, been limited to national or statewide efforts which can underestimate the amount of...

A quantitative continuous variable that reflects the risk of tree dieoff during a significant drought period (SPI48 drought = -2).

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...

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

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

This metric expresses the amount of total existing, aboveground, live tree stem biomass measured in dry weight tons per acre for the Sierra Nevada region. This metric can be...

Structure Exposure Score is an integrated rating of wildfire hazard that includes the likelihood of a wildfire reaching a given location along with the potential intensity and...

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

Aquatic native species richness is a measure of species biodiversity, and is one measurement used to describe the distribution of overall species biodiversity in California for...

Time Since Last Fire (TSLF), from the Fire Return Interval Departure (FRID) map, provides information (in years) to indicate the length of time since an area last burned.
