. Characteristics and hybridization of important intermountain shrubs. Chenopodiacae; Shrubs Great Basin. frequent codominant or subdominant species with shadscale in areas where they occur together. Numerous ecotypes of shadscale enable it to grow over a wide range of sites. Use: Shadscale, in contrast to fourwing saltbush, becomes rigid and spiny as it matures, and during the winter some forms become nearly leafless. However, persistence of leaves varies greatly among areas of occurrence. The spiny characteristic saves this species from heavier grazing than it would otherwise receive and is believed to be a factor in its survival. Shadscale, nevertheless, is palatable to all classes of livestock; the seeds are the most preferred and nutritious part of the plant [ Forest Service 1937). According to Sampson and Jespersen (1963), as the leaves and fruits drop in the autumn, they often accumulate around the parent shrubs. Livestock readily seek this accumulation. Sampson and Jespersen (1963) gave shadscale a browse rating of good to fair for sheep, goats, and deer; fair for cattle; and poor to useless for horses. Hutchings (1952) recorded heavy local damage to productive shadscale range by a snout moth (Pyralidae). The moth damage cleared the way for invasion of noxious halogeton [Halogeton glomeratus). Since shadscale is generally more salt tolerant than fourwing, it apparently could be used for restoration of and soil stabilization on salt-bearing ranges. However, most trials have shown the species to be difficult to establish from direct seeding. It does establish well from transplanting in the early spring when soil moisture remains high for at least 6 weeks. Paradoxically, over a period of years, it shows good natural reproduction. Evidently, a seed source builds up in the ground to sprout and become established during favorable springs. >4tr/p/ex corrugafa (mat saltbush) Mat saltbush is a low shrub that forms dense, extremely prostrate, nearly white mats
