This layer shows the predicted probability of Pacific fisher ( Pekania pennanti ) occurrence or potential habitat quality. This species is found in the Northern California and...

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

These data are derived using analysis described in Glenn et al. (2017). The authors have **** developed a landscape-scale model to predict the distribution and density of the...

This is a measure, expressed as a relative index (0-1), of suitability (or similarity) of forest structure and composition for Northern Spotted Owl (NSO) ( Strix occidentalis...

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...

These data track changes in Northern spotted owl habitat suitability from 1993-2022. The primary purpose of this ongoing monitoring is to track changes in habitat that could be...

The Northern goshawk is a species of special concern to the US Forest Service, but it is not federally, or state listed at the present time and has therefore been identified as...

Winter Steelhead Distribution June 2012 Version This dataset depicts observation-based stream-level geographic distribution of anadromous winter-run steelhead trout,...

Summer Steelhead Distribution October 2009 Version This dataset depicts observation-based stream-level geographic distribution of anadromous summer-run steelhead trout,...

The Northern California Distinct Population Unit (DPU) of Steelhead Trout ( Oncorhynchus mykiss) is a threatened species. This distinct population segment, or DPS, includes...

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 Southern Oregon/Northern California Evolutionary Significant Unit (SONCC ESU) of Coho Salmon was listed as threatened under the ESA on May 6, 1997. National Marine Fisheries...

Large trees are important to forest managers for multiple reasons: they have a greater likelihood of survival from fire; they are an important source of seed stock; they provide...
