Arctostaphylos morroensis is a species of manzanita known by the common name Morro manzanita. This shrub is endemic to San Luis Obispo County, California, where it is known only from the vicinity of Morro Bay.

Distribution

[edit]

There are 18 occurrences of the Arctostaphylos morroensis plant, and it is abundant in some local areas.[2] It is limited to a specific type of substrate known as "Baywood fine sands", a type of sandy soil which originated in the Pleistocene as windblown sand dunes.[3] The plant is found on less than 900 acres of coastal sage scrub and chaparral habitat, sometimes forming monotypic stands on hillsides.[3]

Two thirds of its habitat is privately owned, some of it is slated for development, and its habitat requirements are narrow; these and other problems led to the plant's being listed as a threatened species in 1994.[3] Some of the plants are protected within Montaña de Oro State Park.[3]
