7 serviceberry seed was tested with the tetrazolium test on February 10, 1977 and was round to be 87 percent viable. It will be of interest to see if there is any germination in 1977 of the spring 1976 planted serviceberry. Grasses Seedling numbers per 20-foot row for many of these grass species ' are high (Table 2). Numbers 61 and 60, Bromus marginatus and Elymus glaucus, respectively, were from seed that vas collected on the Colowyo properly and one might expect species that are found growing on the property natively would do well on the revegetation test plot, both from the standpoint of vigor (Appendix Table 3) and number of seedlings. Bromus marginatus also produced a large amount of viable seed and the ability of a plant to seed itself and disperse is very- - -important for a species used in reclamation work. In future years, the measurement of dispersion with the use of cover values will be investigated for the individual species seedings. Several of the wheatgrasses, basin wildrye, Russin wildrye, the two grass species mentioned above and others did well enough to be considered for reclamation work on the Colowyo mine. Sudan grass also did very well in the seedings; Sudan grass was seeded in the individual species seedings with the idea that it could be used as a nurse crop. • Arizona fescue (21) did very poorly in the 1976 results (Table 2). We suspect that the seed may have been bad in this case; thus, we reseeded the 1975 seedings of Arizona fescue on September 20, 1976 with Arizona fescue (78). Again, some interesting comparisons can be made between spring and Fall seeding. Both western wheatgrass "Arriba" and Bromus marginatus were seeded in the fall of 1975 and the spring of 1976; the fall seeding did far better than the spring seeding. Forbs Several of the forb species did well and others did very poorly. In some cases, such as Astragalus (55) or Aster (30), we suspect that the seed was not viable rather than the plant being unable to survive on the Colowyo site. Arrowleaf balsamroot has a high seedling number for 1976 but late in the fall many of the seedlings appeared to be succumbing to moisture stress. The four penstemon species did very well in the individual species seedings and there are legumes such as alfalfa, yellow sweet clover, crownvetch, and lupine (Table 3) that did well. High numbers of seed- lings are recorded for Utah sweetvetch; this is encouraging because Utah sweetvetch is a legume that is found natively on the Colowyo property. •
