Threat ImpactVery high - high
Range Extent5000-20,000 square km (about 2000-8000 square miles)
Number of Occurrences21 - 80
Rank Reasons
Restricted to serpentine wetlands of southwestern Oregon and northern California. Total plant numbers are low and although there are about 66 occurrences, threats from mining are immediate with potential for major impacts.
Range Extent Comments
Known only from the Siskiyou Mountains of southwestern Oregon and extreme northern California (Josephine and Curry Counties, Oregon and Del Norte County, California) and one disjunct population at Red Mountain in Mendocino County, California (Kagan et al. 2006).
Occurrences Comments
About 56 element occurrences known in Oregon and 10 in California.
Threat Impact Comments
Threatened by mining activities, wetland alteration, fire suppression, and off-road vehicles (Kagan et al. 2006; CNPS 2009). Mining, both placer and laterite mining for heavy metals, is a major threat for this species. Specific effects would be the direct removal of the overburden, road construction and other associated mining activities, water diversion, compaction of soils by heavy equipment and erosion. Diversion of water for residential use and grazing are also threats. In addition, off-road vehicles reportedly continue to damage "protected" habitat in the Siskiyou National Forest (Barbara Ullian pers. comm. 2000). Gentiana setigera may also be threatened by collection (Kagan et al. 2006).
