Study results on upland sites. Table 5 shows the 

 general pattern of recovery for upland serai community 

 life-forms and the most important species within each 

 life-form. 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. 



Table 5.— Upland cover and volume nneans for stands 16 through 27. Stand 15 was not included in 

 these means because it was disturbed by grazing in 1982. Height data were not taken for 

 grasses in 1978
