* Metric Name: Pacific Marten Suitable Habitat (Replaced June 2024)  

* Tier: 2  

* Data Vintage: 04/2023  

* Unit Of Measure: Categorical - classified into one of the following habitat suitability categories:

  

* Metric Definition and Relevance: The Pacific martin is a species of special concern, but it is not federally, or state listed at the present time. It is identified as a focal species by Region 5 of the US Forest Service. The Pacific marten is a high elevation, old forest associate that is sensitive to forest management and is an important carnivore in high elevation food webs. This metric evaluates the 1000 ac around each 30m pixel to determine if it meets the minimum habitat requirements to support a territory.  

* Creation Method: CWHR classifications are based on a combination of FVEG 2023 for canopy cover, size class and vegetation type. The vegetation data includes a variety of tree, shrub, grassland, and water dominated habitats. Species are considered present, and habitats considered suitable for each 30m cell for which the canopy cover-size-vegetation combination have been deemed highly or moderately suitable for either the reproduction or foraging of that species in the California Wildlife Habitat Relationship database. The suitable habitat layer has been further refined and clipped to the U.S. Fish and Wildlife Service species range extent. Habitat which meets the following criteria is considered suitable:

  * Suitable foraging vegetation types: WHRTYPE = MRI, RFR, DFR, WTM, LPN, SCN, MHC
  * Suitable foraging habitat: size/density classes = 4M, 4D, 5M,5D, 6
  * Suitable denning vegetation types: WHRTYPE = MRI, RFR, DFR, LPN, SCN, MHC
  * Suitable denning habitat: size/density classes = 4M, 4D, 5M, 5D, 6
