Annual Burn Probability
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... -
Fire Return Interval Departure (Frid) - Mean Condition Class
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... -
Fire Return Interval Departure (Frid) - Mean Percent - Since 1970
Percent FRID (PFRID) quantifies the extent in percentage to which recent fires (i.e., since 1970) are burning at frequencies similar to those that occurred prior to... -
Fire Return Interval Departure (Frid) - Current Fire Return Interval -Since 1970
The fire return interval departure (FRID) analysis quantifies the difference between current and pre-settlement fire frequencies, allowing managers to target areas at high risk... -

Wildlife Species Richness
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... -
Wildfire Hazard Potential August 2022
Wildfire Hazard Potential (WHP) is an index that quantifies the relative potential for wildfire that may be difficult to control. WHP can be used as a measure to help prioritize... -
Wetland Diversity
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... -

Unarmored Threespine Stickleback Habitat
This is a dataset representing the boundaries for the Unarmored threespine stickleback ( Gasterosteus aculeatus williamsoni ) as understood by the United States Fish and... -
Tree Mortality - Past 5 Years
The dead tree canopy cover fraction change from the Mortality Magnitude Index (MMI) for eDaRT events. This metric is provided to complement data (in terms of spatial resolution... -
Tree Mortality - Past 1 Year
The dead tree canopy cover fraction change from the Mortality Magnitude Index (MMI) for eDaRT events. This metric is provided to complement data (in terms of spatial resolution... -
Tree Cover Ratio
Total tree cover as measured by the fractional non-overlapping absolute tree cover, viewed vertically. Provides a first order measure of vegetation type when combined with... -
Trail Density
A raster dataset representing density of trails in the Southern California Region. -
Total Fuel Exposed to Fire
This is the sum of standing dead, ladders, and the dead and down, documented above. This metric quantifies the total amount of biomass available to contribute to the extreme... -
Total Fuel (Dead and Down) Load
Stephens et al. (2022) note that total dead/down values over 20 (short) tons/ac (40 Mg/ha) resulted in high severity in 56% of the pixels. Higuera and Abatzoglou (2020) note... -
Total Carbon
Identifying ecosystem carbon is essential to land managers and the Total Carbon (F3) metric provides an estimate of the amount of existing carbon and its location on... -
Total Aboveground Carbon
Identifying ecosystem carbon is essential to land managers and the Total Aboveground Carbon metric provides an estimate of the amount of existing carbon and its location on... -
Time Since Last Disturbance
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...
