High – There is both suitable habitat associated with the species and a historical record of the species on or in the immediate vicinity of the project site, within 5 miles. Moderate – The diagnostic habitats associated with the species occur on or in the immediate vicinity of the project site, but there is not a recorded occurrence of the species within the immediate vicinity, within 5 miles. Some species that contain extremely limited distributions may be considered moderate, even if there is a recorded occurrence in the immediate vicinity. Low – There is a historical record of the species in the vicinity of the project site and potentially suitable habitat onsite, but existing conditions, such as density of cover, prevalence of non-native species, evidence of disturbance, limited habitat area, isolation, substantially reduce the possibility that the species may occur. The site is above or below the recognized elevation limits for this species. None – A combination of the nearest recorded occurrence of the species is not within the near vicinity of the site, and the habitat onsite is marginally suitable at best. There is virtually no potential for this species to occur on the project site and further discussion is excluded from this report.
