Arctostaphylos pumila is a perennial evergreen shrub endemic to the Monterey Bay coastline, Arctostaphylos pumila has two interchangeable common names. The Dune Manzanita because of how A. pumila favors Monterey Bay’s sand dunes and sea bluffs; The Sandmat Manzanita because of how A. pumila stays low to the ground and forms flat, creeping “mats” as it grows (hence, a “sandmat”). Unlike most manzanita species, A. pumila’s red bark does not shred/peel and it mostly collects water from the fog layer that frequently occurs in this area. A. pumila is currently Critically Imperiled due to urbanization and frequent military activity from nearby Ft. Ord.
