Rank Reasons
Cinna bolanderi is a perennial grass that is endemic to California, USA, in the High Sierra Nevada. It grows along streambanks and in wet meadows or other moist sites of montane coniferous forest. Threats include alterations to hydrology, trampling, logging and grazing but threats have not been evaluated at most occurrences. Additionally, information on plant presence and abundance is needed for half of the occurrences.
Range Extent Comments
Cinna bolanderi is endemic to California, USA, where it is found at mid elevations of the central and southern High Sierra Nevada (Hickman 1993, Jepson Flora Project 2023).
Threat Impact Comments
This species is threatened by alterations to hydrology, trampling, timber harvest, trash dumping, and grazing (CNDDB 2023).
