Changes in shrub fecundity in fourwing saltbush browsed by cattle
Shrub fecundity is critical to long term persistence of fourwing saltbush (Atriplex canescens (Pursh) Nutt.) populations at our research site on the shortgrass steppe in Colorado. We conducted a 2-year experiment to test hypotheses concerning the impact of cattle-browsing on fecundity-related variables in fourwing saltbush. Protection from cattle browsing was significantly associated with flora...
متن کاملHeifer Performance Under Two Stocking Rates on Fourwing Saltbush-Dominated Rangeland
The efficiency of livestock production in shortgrass steppe may be increased by grazing fourwing saltbush (Atriplex canescens [Pursh] Nutt)-dominated rangeland in late fall and/or early spring, but there is a paucity of information concerning stocking rates and animal gains. The objective of this study was to compare the effects of light and moderate stocking rates on weight gains of heifers gr...
متن کاملSeed longevity and seeding strategies affect sagebrush
Three hypotheses were tested relating to Wyoming big sagebrush (Artemisia tridentata Nutt. ssp. wyomingensis (Beetle and Young) revegetation on coal-mined land in Wyoming: (1) that fourwing saltbush (Atriplex canescens (Pursh) Nutt.) seeded > 2.2 kg pure live seed (pls)/ha would exclude sagebrush, (2) the contrasting view that the saltbush, as a "pioneer plant", facilitated sagebrush stand deve...
متن کاملSaltbush – a case for reintroduction
This paper reviews historical, philosophical and socio-cultural information as a means of explaining why saltbush in Australia has declined. That decline coincided with introduced hard hoofed animals overgrazing native pastures and was compounded by land clearing. Over time, losing ecosystem diversity degraded vegetation, soil and water resources; subsequently, watertables rose. A benefit of sa...
متن کاملEnvironmental Factors Influencing Gardner Saltbush Seed Dormancy Alleviation
Pregermination treatments applied to seed of Gardner saltbush, [ALriplexgar&cri(Moq.) D. Dietr.] were evahtated for alleviation of seed dormancy. Treatments selected simulated conditions the seed might be exposed to in its natural environment, including dry afterripening, scarification, leaching, and cold stratification. Germination response to individual treatments was equal to or higher than ...
