Arctostaphylos obispoensis is a species of manzanita, known by the common names bishop manzanita and serpentine manzanita, endemic to California. [2]
The plant is endemic to the southern Santa Lucia Mountains, in the Central Coast region of California. [2] It is found primarily in San Luis Obispo County, and extends into southern Monterey County. [2] [3]
It grows in chaparral and closed-cone pine forest habitats, usually on serpentine soil. It is found at elevations of 60–950 metres (200–3,120 ft). [4]
It is protected within the Cuesta Ridge Botanical Special Interest Area of the Los Padres National Forest, growing in the endemic Sargent cypress (Cupressus sargentii) forest. [5] The species is listed on the California Native Plant Society Inventory of Rare and Endangered Plants as a rare but not currently endangered species. [6]
Arctostaphylos obispoensis is an upright shrub or multi-trunked tree growing to 1–4 metres (3.3–13.1 ft) in height. [2] [4]
The small branches and newer leaves are woolly. The mature leaves are glaucous-gray, hairless, and oblong (northern range) to widely lance-shaped (southern range), and up to 4.5 centimeters long. [4]
The inflorescence is a dense cluster of white urn-shaped and downward facing "manzanita" flowers.
The red fruit is a round waxy drupe, 9–14 millimetres (0.35–0.55 in) in diameter. [4]
Arctostaphylos auriculata is an endangered species of Arctostaphylos endemic to California, and limited in geography to the area surrounding Mount Diablo, in Contra Costa County.
Dwarf forest, elfin forest, or pygmy forest is an uncommon ecosystem featuring miniature trees, inhabited by small species of fauna such as rodents and lizards. They are usually located at high elevations, under conditions of sufficient air humidity but poor soil. There are two main dwarf forest ecosystem types, involving different species and environmental characteristics: coastal temperate and montane tropical regions. Temperate coastal dwarf forest is common for parts of Southern California. Montane tropical forests are found across tropical highlands of Central America, northern South America and Southeast Asia. There are also other isolated examples of dwarf forests scattered across the world, while the largest dwarf forest is found in the Philippines.
