San Diego County and Baja California, Mexico [2].
Twenty-one occurrences on Conserved Lands in MUs 4 (Mission Trails Regional Park), 6 (Carmel Mountain Preserve, City of Carlsbad Municipal Golf Course, Del Mar Highlands, Del Mar Mesa Open Space, Kelly Ranch Habitat Conservation Area, Los Penasquitos Canyon Preserve, Lusardi Creek Preserve, Manchester Mitigation Bank, Oakcrest Park, Overlook Park, Poinsettia Place, Rancho La Costa Habitat Conservation Area, San Dieguito Regional Park, The Crosby at Rancho Santa Fe), and 7 (Crest Canyon Preserve, Overlook Park, Torrey Pines State Natural Preserve).
FE [2].
Maritime and sandy chaparral [2]. Sandstone terraces and bluffs [3]. Mesa topography in naturally fragmented habitat.
Ericaceae family [2].
Perennial burl-forming evergreen shrub [2, 3]. Dependent on fire for germination [3].
Bloom period is December- April [2].
Possibly can regenerate from burls and seeds [3]. Plants can produce a large number of seeds, but with large annual fluctuations [4]. Small seed bank. Flowers are self-incompatible and are visited by flies, bees, and bee-flies [4, 5]. Fruits generally fall close to parent plant where they are consumed by rodents [4]. Occasionally, seeds are eaten by foxes and coyotes and transported a distance.
Urbanization, agricultural conversion, fire and edge effects (nonnative plants, fuel modification, and human access) [3].
Easily confused with eastwood manzanita (Arctostaphylos glandulosa ssp. glandulosa) [1]. Monitored every 3 years by the City of San Diego. Buds typically sprout after fire [3].
