* Metric Name: Spotted Owl Habitat CWHR  

* Tier: 3  

* Data Vintage: 04/2023  

* Unit Of Measure: 0 = not suitable, 0.66 = moderately suitable. 1 = highly suitable.  

* Metric Definition and Relevance: This layer shows highly and moderately suitable habitats for the reproduction and feeding of Spotted Owl ( _Strix occidentalis_ ). The analysis is based on the habitat values found in the California Habitat Relationships (CWHR) model for spotted owls. These values apply to the species in general and not specifically to the Northern Spotted Owl subspecies. These data are included because California spotted owls may occur in the far eastern portion of the Northern California Region that is covered in this RRK.  

* Creation Method: CWHR classifications are based on a combination of FVEG canopy cover, FVEG size class and vegetation data. 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 the reproduction or feeding of that species in the California Wildlife Habitat Relationship database. Each cell was assigned the maximum suitability value, i.e. if a cell was moderately suitable for feeding and highly suitable for reproduction, it was considered highly suitable.
