Pre‐fire grazing and herbicide treatments can affect post‐fire vegetation in a Great Basin rangeland
Management of wildfire associated with spread the highly invasive annual grass Bromus tectorum (cheatgrass) is a critical need in western U.S. We investigated utility coupling common rangeland management strategies pre-fire to modify post-fire plant community outcomes. used long-term, large-scale experiment test separate and combined effects targeted grazing (spring fall), native seeding (seedi...
Cbeatgrass (Bromus tectorum L.) has become the dominant species over large areas of rangeland in the Great Basin region of the western United States. Rapid germination at low temperature may contribute to the competitive success of cheatgrass in areas formerly dominated by native sagebrush and bunchgrass species. The objectives of this study were to determine whether seed priming could be used ...
ETHNOPHARMACOLOGICAL RELEVANCE Sempervivum tectorum L. (Crassulaceae), known as houseleek, is used in traditional medicine in the treatment of ear inflammation. It can be spread as a pack on wounds, sores, burns, and abscesses and also on painful areas attacked by gout as a refrigerant and astringent. Drinking tea prepared from leaves of S. tectorum is recommended for ulcer treatment. The prese...

Two new species of the genus Aegyptobia Sayed and 1 new species of Phytoptipalpus Trägårdh are described from Iran: A. bromi sp. nov. from Bromus tectorum (Poaceae); A. nazarii sp. nov. from Poa bulbosa L. (Poaceae); and P. kurdistaniensis sp. nov. from wild rose bushes, Rosa woodsii (Rosaceae). This is the first record of Phytoptipalpus from Iran. We also redescribe Aegyptobia beglarovi Livsch...
Plot-scale field studies were conducted to evaluate the efficacy of steam for the control of cropland weeds in comparison with common herbicides. Weed densities, biomass, or emergence after treatment were measured. Steam (3,200 kg/ha, energy dosage equivalent to 890 kJ/m2, speed of 0.8 m/s) and glyphosate (560 g ai/ha) gave similar control (. 90%) of seedling common lambsquarters and seedling r...
Cheatgrass (Bromus tectorum L.) is the most widespread invasive weed in sagebrush ecosystems of North America. Restoration of perennial vegetation is difficult and land managers have often used introduced bunchgrasses to restore degraded sagebrush communities. Our objective was to evaluate the potential of ‘Vavilov’ Siberian wheatgrass (Agropyron fragile [Roth] P. Candargy) to establish on chea...
The expansion of piñon-juniper woodlands the past 100 years in the western United States has resulted in large scale efforts to kill trees and recover sagebrush steppe rangelands. It is important to evaluate vegetation recovery following woodland control to develop best management practices. In this study, we compared two fuel reduction treatments and a cut-and-leave (CUT) treatment used to con...
