Endemic to California: Phlox dolichantha occurs in San Bernardino County. Threats include urbanization and recreational activity.
Range Extent Comments
California endemic found in the San Bernardino Mountains. Area of the minimum convex polygon, range extent, is 235 sq km.
Occurrences Comments
45 EOs: 29 surveyed in the last 20 years (15 in the last 5 years) and 16 EOs not surveyed for more than 20 years (CNDDB 2013).
Threat Impact Comments
The main threats listed are development such as the building of residential facilities, recreational camps, and a resort. In addition to mining and road related maintenance work, a couple of sites reported sightings of the exotic cheat grass. Some off road vehicle use and continuing recreational use of the many trails that bisect the areas were noted as well (CNDDB 2013).

Habitat

Open places within coniferous forest communities (Yellow Pine Forest, Red Fir Forest, Montane Coniferous Forest), including pebble plain areas (areas of dense clay soils armored by a lag gravel of quartzite pebbles that form openings of low cover and are dominated by herbaceous, cushion-forming species). 1830 - 2970 m.
