Description:

Arctostaphylos montaraensis is another Bay Area manzanita that are endemic to Daly City’s San Bruno Mountain and across multiple state parks in Southern San Francisco including Montara Mtn. Though a coastal scrub, this erect evergreen shrub prefers moderate montane elevations (about 1000 ft) where it grows in sedimentary rock like sandstone and loose granite. This dense shrub is identifiable by its reddish-brown bark, light green/grey glandular leaves, and white blossoms that occur through January and March. A. montaraensis is a Critically Imperiled species with only four occurrences left, all of which are threatened by fire suppression, human development, and non-native plants.
