2. Topography: Carex torreyi typically occurs on northeast- 

 and north-facing slopes of ridges or mesas, but within 

 drainage valleys on the slopes, at a change in slope from (or 

 to) steep slopes to slight or moderate ones, of from 2 to 10, 

 and occasionally 20 percent. They often occur at the junction 

 with another side drainage. Elevations range from 1146-1204 

 m (3760 to 3950 ft), but the greatest within any single 

 population is 30.5 m (100 ft). 



3. Soil relationships: Soils are a dark sandy loam with a 

 rich humus component, and typically a thick layer of pine 

 needle litter. The location of the populations at the change
