Most of the burned area was aerially seeded; however, one area in the western portion of the burn was not seeded at the request of the landowner. Stand 19 is located in this area and had only a trace of seeded grass in 1978. Other areas without seeded grass were deliberately included in the study so that their develop- ment could be followed. Stands 21 and 24, near the eastern and western fire boundaries, did not have any seeded grass present in 1978 and stand 18, well within the burned area, had only a trace amount of seeded grass in 1978. It seems likely that initially the seeded grasses would compete most strongly with other herbaceous vegetation and seedUngs of all species. Data from the four stands originally without seeded grasses in figure 6 contrast with the data from the stands where seeded grasses established well. Seeding did produce high herbaceous cover in 1978 and 1979 (fig. 7). Herbaceous cover has declined somewhat from 1979 to 1982 while cover of seeded grasses has declined more rapidly. In 1979 seeded grasses comprised 71 percent of the herbaceous plant layer; in 1982 they had declined to 45 percent of the her- baceous plant cover in those stands with seeded grasses initially. The stands without seeded grasses initially had lower herbaceous cover values in 1978 and 1979 but they had somewhat higher cover values thgui stands with seeded grasses in the summer of 1982 (fig. 8). Tree regeneration data from vegetation plots in upland stands is summarized in table 6. In 1982, seedlings out- side the plots were observed in all stands listed in table 6 except stands 15 and 16. A few larch trees survived the fire in the area of stand 21 and there are some larch seedlings in the area as well as lodgepole pine. Stands 20 thru 27 have lodgepole pine seedlings in the Figure 7.
