“…The soil is classified as a silty clay loam, 36 to 76 cm deep (Ellison 1954). Soil pH is approximately 6.3 and soil moisture varies from 40 to 15% between spring and late fall (Ellison 1954).…”

False hellebore (Veratrum californicum Durand) is a native component of high -elevation, meadow -riparian areas of the mountain West that has increased due to historic heavy grazing. In 1991, a study was established in dense stands of false hellebore to evaluate mechanical and chemical control methods to reduce false hellebore and increase the abundance of the other native herbaceous species in these tall -forb communities. Four control methods consisting of the herbicide glyphosate (Nphenophonomethylglycine), mow, mowing in 2 consecutive years (remow), and tillage were used in 1991 -1992. Each method was evaluated based on (1) reduction of false hellebore stem densities; (2) response of residual understory species; and (3) effectiveness of seeding a perennial grass and forb mixture to sustain initial treatment control. Stem density of false hellebore and nested frequency data for all species were collected in 1991, 1992, 1995, and 1999. The glyphosate treatment was effective in reducing false hellebore stem density which allowed for recovery of the remnant tall -forb community. The till treatment, while effectivefalse hellebore stem density, also eliminated the other species in the community, leaving it open to invasive weeds. The mow and remow treatments did not reduce false hellebore stem density, but did allow for recovery of other components of the tall -forb community. Seeding following control treatments had no effect on false hellebore stem densities due to poor establishment. The mechanical treatments were generally more cumbersome in application and limited to gentle topography and welldrained sites without surface rocks. The application of herbicides is much easier and is adaptable to all types of terrain. The use of the herbicide glyphosate gave the best balance of false hellebore control and recovery of the tall -forb community.

“…Plant species most abundant on heavily grazed sheep range include Stipa lettermani, Agropyron trachycaulum, Achillea lanulosa, Aster, and Taraxacum officinale (Ellison 1954 The successional status of Artemisia tridentata vaseyana is difficult to establish. Morris and others (1976) indicated that it is probably a seral species that increases its range and density on disturbed sites.…”

“…Sheep tend to prefer forbs over grasses, thus an overgrazed sheep range would be characterized mostly by low value grasses (Ellison 1954). As overgrazing continues, the less-preferred perennial grasses decline so that unpalatable forbs and annuals predominate.…”

“…Because there are no apparent remnants of the original vegetation, opinions differ regarding successional status of present vegetation and character of the pristine vegetation. Ellison (1954) describes the original plant community as mixed-upland herb dominated by tall forbs, whereas Sampson (1919) considers wheatgrasses to be the primary species of the herbaceous climax (that is, what he merely refers to as summer range). Our recent research (Klemmedson and Tiedemann 1994) tends to support Sampson's thesis.…”

Phosphorus (P) and sulfur (S) in soil and parent material are important in the accumulation of nitrogen (N) and organic carbon (C org ) in soils. In an observational study, the role of P and S in soil development was explored on a small knoll in the Wasatch subalpine summer range of central Utah that had been severely eroded during uncontrolled grazing in the late 1800s. Vegetation, litter, soil, and parent material were sampled along a transect across six strata forming highly visible narrow, concentric rings around the knoll. Even-numbered strata were characterized by large amounts of surface rock and sparse vegetative cover. Odd-numbered strata had less surface rock and visibly greater vegetative cover. Data for vegetation, litter, and soil surface properties displayed highly consistent peak and valley patterns for odd-and even-numbered strata with significant differences for 9 of 10 of these properties between the two strata groups. Organic C, potassium (K), and S of the parent material, and available N (N av ), P (P av ), and S (S av ) and exchangeable K (K ex ) of the 0-to 15-cm soil layer also displayed peak and valley patterns. Multiple regression of herbage yield on C org and S of soil parent material, and P av and (K ex ) of the solum gave high R 2 s of 0.94 and 0.93. Multiple regression of grass yield on C org and K ex of the 0-to 15-cm soil layer had R 2 = 0.95. Based on results, the hypothesis that P of the parent material has influenced soil and plant development of these strata was rejected. The data subtly suggest that sulfur may play a key role in the development of these soil-plant systems. Stipa lettermanii Vasey and Cymopterus lemmonii Welch were strongly, but oppositely, correlated with most attributes studied, thereby suggesting these species may play important indicator roles of soil-vegetation development.
