Reports a study in which four unmanaged, even-aged stands of second-growth mixed hardwoods 67-97 years old, dominated by Quercus spp., near Asheville, North Carolina, were sampled by a leaf trapping technique similar to one described earlier [see FA 34, 3026]. Criteria for judging the performance of the technique were the repeatability of the sampling technique from one year to the next and the precision of its estimates. Data are presented for leaf collections made in 1969 and 1970, on the same plots without rearranging the traps on the plots; they indicated that the method of trapping gave reliable results. An advantage of the technique is that it has little disruptive effect on the forest.
