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... -
NASA WERK Lidar - Los Angeles (1m, 2023)
1-meter resolution lidar-derived topographic products covering the greater Los Angeles area, collected in 2023 as a pre-fire baseline. This dataset serves as a reference for... -
Shrublands With Low Natural Regeneration Potential Post-Fire
Identifying locations where shrubland vegetation will not recover naturally post-fire is a challenge given the vast areas that are regularly burned in southern California. When... -
Pacific Fisher Suitable Habitat
The Pacific fisher population in the southern Sierra is federally listed **** as a threatened population and resides primarily on National Forest System lands. Habitat... -
Seral Stage Distribution
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... -
CWHR Vegetation - Density
Vegetation maps are important for characterizing many important features of a landscape such as wildlife habitat, fuels conditions, forest composition, and carbon. Such data are... -

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... -
FSH Fine-Scale Heterogeneity Index
A key component of forest structure descriptions is the spatial heterogeneity (i.e., tree clumps and gaps), which influences vegetation growth, competition, and succession,... -
Density - Snags - 20" - 29.9"
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... -
