2. Topography: The population occurs on the west and 

 southern slopes of a small hill or knoll on a mesa top. Small 

 sandstone outcrops are present. Elevation ranges from 392 to 

 3940 ft. 



3. Soil relationships: The soil is a very sandy loam. Most 

 of the plants are growing in areas below sandstone outcrops. 



E. Population biology and biologica^ interactions 



1. Population Size and Condition: The population consists of 

 about 50 plants, mostly within an area of less than an acre, 

 with a few individuals occurring up to 0.2 mile from the main 

 area. 



2. Reproduction: Outcrossing. 



3. Competition: The plants grow in partial shade on slopes 

 with sparse vegetation (ca 70 percent bare ground) , but with 

 abundant pine needle litter. A few plants are present in open 

 ground along and near 2-tracks. This suggests that the 

 species is not adapted for competition within denser 

 grasslands. 



4. Herbivory: The sparse vegetation does not make the site an 

 area of high grazing impact. 



F. Assessment and management recommendations: While major threats 

 have not been identified for Phlox andicola , it is only known from 

 one small population and further status review as a watch species 

 is appropriate.
