Interseeding Shrubs in Cheatgrass with a Browse Seeder ScalperGuinta, B. C.; Christensen, D. R.; Monsen, S. B. (Society for Range Management, 1975-09-01)Four browse species and a mixture of the four were interseeded into a uniformly dense cheatgrass stand with a browse seeder-scalper on deer winter range south of Manti, Utah. Four different width–4-, 8-, 16-, and 24-inch-scalping attachments were used to determine their relative effectiveness in reducing competition between cheatgrass and developing shrub seedlings. Scalping with the wider attachments resulted in substantial increases in shrub seedling survival. Reduction of cheatgrass density was most marked during the first growing season following planting. Thereafter, cheatgrass fully reoccupied first the narrower and then the wider scalps. In terms of numbers of plants surviving after 5 years, antelope bitterbrush, Nevada ephedra, and the mixture proved most responsive to increases in scalp width. Cliffrose and fourwing saltbush were less so. Herbage production of individual shrubs regardless of species showed no response to increasing scalp width. However, production for an entire plot where the effect of number of plants was included increased markedly with increases in scalp width. Cheatgrass competition, although it limited growth of all the planted shrubs, was less limiting to fourwing saltbush than to the other three shrubs.
