Applying Coherex to McGill Tailings. <br />EVALUATION OF RESULTS <br />A germination count of the vegetative plants on the stabilized plot, made <br />approximately 1 month after seeding, showed that 12, 24, and 52 percent, <br />respectively, of the grasses, legumes, and winter wheat had germinated. These <br />plants displayed growth ranging up to 5 inches in height. One week later a <br />killing frost destroyed most of the legumes, which were still in the cotyledon <br />(earliest leaf) st`'age. <br />Plant counts were made the following year, on Ptay 14 and September 5, <br />1968. These counts, especially the latter, indicated that the primary objec- <br />tive was attained--the area eras stabilized against wind erosion and native <br />plant species were encroaching onto the stabilized plots. The Siberian pea <br />t rEE mss tie cr.ly one of the 11 species original l;• planted that either did not <br />ger-:irate or failEd to sur~~ice to the September 5, 1968, counting. Eleven <br />a:ild species had encroached end were growing. Table 1 summarizes the seeds <br />pia::ted and germination and survival rates.
