Rank Reasons

Endemic to California, Lupinus antoninus is known from 4 extant occurrences, in three counties. Threats include hybridization with Lupinus albifrons var. collinus. Research is needed to assess the true threat of hybridization, the possible threat of climate change and to monitor population reproduction success, population health and sizes. All four known populations occur on USFS lands at higher elevations and experience few or no human-caused threats. There are only about 85 plants known in the wild.

Range Extent Comments

Range extent is measured as 359 sq km.

Occurrences Comments

4 known EO's as of 2010; there is no backlog of data. Three are historical, but this may not be too meaningful since this plant takes effort to monitor.

Threat Impact Comments

There are few to no human caused threats to Lupinus antoninus since it occurs in remote parts of the higher elevations on the Mendocino National Forest. However, it's occurrence in the higher elevations means it is possible that global climate change could negatively affect this species. Some have mentioned that hybridization could be threat as well. It should be monitored more frequently to get a better idea about trends.

Ecology & Habitat

Habitat
