Ponderosa Loam Palmer Divide Palmer Divide

Description

The native plant community is approximately 80 to 90% (air-dry weight) grasses, 10 to 15% forbs and 2 to 5% shrubs. Three major bunch grasses dominate the plant community; mountain muhly, Arizona fescue, and Parry oatgrass. These three comprise 70% of the total annual production of this site. Grasses making up lesser percentages are western wheatgrass, prairie junegrass, needleandthread, and blue grama. A small amount of other grasses, a variety of forbs, and a few shrubs comprise the rest of the total annual production. Trees are normally absent from the native plant community but an occasional ponderosa pine may invade the site from adjacent woodland.
