| − | '''Herbaceous''' vegetation is - according to the [[USDA]] terminology - ''"a [[general cover]] category consisting of predominantly perennial herbaceous plants or noncultivated annuals or both. The tall woody canopy cover is less than 5 percent, and the short woody canopy cover is also less than 5 percent. Arid rangeland and desert can fall into this category although vegetation density and percentage of ground cover may be low. ''
