• <br />C, <br />6. Red fescue, Kentucky bluegrass, and Redtop have all shown up well <br />in the 1971 plantings. many selections of red fescue are <br />commercially available and some are being tested by Robin Cuany. <br />The performance of mountain brome was satisfactory; however, it is expected <br />to be a relatively short-lived species. <br />Slender wheatgrass (Yariety ?) which rated good the first few growing <br />seasons has nearly all died. <br />The Durar variety of hard fescue has only shown up as fair in these studies; <br />it experienced considerable winter kill during the first few growing <br />seasons. The vigor of individual surviving plants has been fair to good. <br />Intermediate and pubescent wheatgrasses have proven to be less ~idaptable to <br />the upper subalpine than a number of other readily available spec:ies. <br />There were considerable differences in persistence and growth between the <br />western wheatgrass seeded in 1969 as compared to the one seeded in 1971. <br />Neither seed source can be recommended for high-altitude rE~vegetation, <br />however the differences in performance between the seed sources indicate <br />that selections made from native high-altitude stands may have good <br />potential in revegetation programs. <br />Canada bluegrass was slow to establish and suffered considerable winter kill <br />in 1976 and 1977. <br />The selections of streambank wheatgrass, beardless wildrye, rind Arizona <br />fescue used in the study initially produced fair to good stands, but they <br />have not persisted. <br />No seedlings of mountain muhly were found. The failure of this species to <br />establish is probably the result of nonviable seed. <br />25 <br />
