Shrub cover and volume £ire low for the first 5 years since shrub resprouts are scattered on most upland sites. Stand 19 represents one of the exceptions to this trend. Shrub seedlings were noted in many stands during the siunmer of 1982. Herbaceous species, particulsirly grasses, dominate most sites. Figure 5 shows the pattern of grass development, us- ing the mean cover and volume for £ill upland stands. Pinegrass bloomed profusely during the summer of 1978 and somewhat less energetically in 1979. Subsequent seedling establishment observed in 1979 and 1980 coupled with vegetative spread account for the increase in pinegrass. The reasons for the decline of orchardgrass are unclear.
