Weight loss by filter paper and native herbage is being studied on five meadows in the Sequoia National Park, California, to develop an index to rate of herbage decompostion. Some samples are buried 5 cm deep; others are placed on the surface. All samples are left in place for 1 year. First year results show that the herbge samples provided better estimates of mean loses than the filter paper samples. Weight lost by unburied herbage ranged from 50 to 75 percent, depending on the test site. These result are provsionally acceptable as an index to rate of herbage decompostion.
