Range Extent200,000-2,500,000 square km (about 80,000-1,000,000 square miles)
Rank Reasons
Coastal species ranging from California, where it appears to be most common, to British Colombia. There are multiple threats to the species including invasive plant species, trampling, off-road vehicles, storm surges, and herbivory. More information regarding the number of EOs is needed to asses this species but G3G4 seems reasonable given the level of threats and the number of herbarium collections and the EO data collected in British Colombia.
Range Extent Comments
Occurs in coastal regions from Monterey Bay area of California north Oregon, Washington, and British Columbia.
Occurrences Comments
There are 5-6 EOs in British Columbia. There are 4 or 5 sites known from OR (Kagan, pers. comm. 2013). Over 150 observations are documented from CA but they haven't been reviwed to determine their status or level of overlap (Lazar pers. comm. 2013).
Threat Impact Comments
Threats include invasive plant species, trampling, off-road vehicles, storm surges which are increasing in frequency with sea level rise, and herbivory (Arnett, Bennett, and Lazar pers. comm. 2013).
