This layer shows highly suitable habitats for the reproduction and feeding of Nuttall's Woodpecker ( Dryobates nuttallii ) within the species' range.

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...

A raster dataset representing density of trails in the Southern California Region.

This is a dataset representing the boundaries for the Unarmored threespine stickleback ( Gasterosteus aculeatus williamsoni ) as understood by the United States Fish and...

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

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...

Plants respond to conditions in their immediate vicinity. Thus, to understand the vegetative moisture stress during drought, it is important to measure the local moisture...

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...

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 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...

The ember transport model used in WildEST tracks the travel of embers from each source pixel to downwind receiving pixels. The relative number of embers landing on a given...

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...

This dataset shows the boundaries of groundwater basins and subbasins as defined by the California Department of Water Resources as last modified by the Basin Boundary Emergency...

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...

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...

Basal area (BA) is a common forest structure measurement that provides a useful index of forest and habitat condition. Basal area is the cross-sectional area of the bole of a...

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...

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...

Stand density index (SDI) helps vegetation managers to identify levels of site utilization and competition to determine management scenarios to meet objectives and is often used...

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...
