Mountain Meadows in the Sierra Nevada of California The vegetation and diverse habitats of mountain meadows in the Sierra Nevada make them concentration points for people and animals. Abundant forage attracts livestock and wildlife, while the scenery attracts hikers and campers. Pack trippers and their animals are also drawn to them. As a result, many mead- ows have deteriorated and some suffer from overuse. Since the early 1960's, Pacific South- west Station scientists have been in- volved in research to improve meadow management. A comprehensive work, "Mountain Meadows in the Sierra Nevada of California," will soon be published to summarize knowledge about meadows for land managers. A portion of the guide will deal with techniques that land managers can use to help restore deteriorated meadows. Some meadows have been so trampled by livestock and people that sod and soil are seriously affected. Erosion has moved nutrients from place to place and eventually altered the kinds of plants that grow there. Other meadows are being invaded by lodgepole pine seed- lings, whose establishment is favored by low snowpacks and early melting. Res- toration can be a slow process because the higher mountain meadows lie, the lower their productivity and the longer it takes land managers to restore them to reasonable use. 14 In addition to helping land managers in the Sierra Nevada ensure the future productivity of meadows, the new guide will classify meadows according to soil and vegetation characteristics and des- cribe how biologically and geologically stable they are. It will also categorize more than 200 plants into "decreasers," "increasers," and "; Land man- agers can tell how "healthy" a meadow is by the relative sizes of these three groups of How frequently certain plants are found tells a lot
