Assessment Notes
Justification
Xeroceps skamania is only known 14 records ,13 from Skamania county in Washington and the Gifford Pinchot in Oregon plus one observation from northern California. Several of these localities have been subjected to megafires while other sites are subject to negative changes in forest management. Given the small number of sightings coupled with the loss of habitat, this is considered a rare species. Even multiplying the number of confirmed records by 500 times, to take into account suitable habitat and the conversion from functional individuals to mature individuals, only gives a population size of 7,500, all occurring in one subpopulation. Thus, precautionarily, the species is assessed as Vulnerable.Geographic range
Xeroceps skamania is known from Skamania county in Washington and the Gifford Pinchot in Oregon (MyCoPortal 2024), plus one observation from northern California (not mapped here) (iNaturalist 2024).Population and Trends
The species is known from 13 records from only a few localities in Washington and Oregon plus one iNaturalist observation from northern California (GBIF 2024, iNaturalist 2024, MyCoPortal 2024). Several of these localities have been subjected to megafires while other sites are subject to negative changes in forest management. Given the limited number of sightings coupled with the loss of habitat, this is considered a rare species. Even multiplying the number of confirmed records by 500 times, to take into account suitable habitat and the conversion from functional individuals to mature individuals (per Dahlberg and Mueller 2011), only gives a population size of 7,500 mature individuals, all occurring in one subpopulation.
