More frequent wildfires and incidences of mega-fires have increased the pressure for fuel treatments in sagebrush (Artemisia) communities. Winter grazing has been one of many fuel treatments proposed for Wyoming big sagebrush (A. tridentata Nutt. subsp. wyomingensis Beetle and A. Young) communities. Though fire risk and severity can be reduced...
Millions of hectares of Wyoming big sagebrush (Artemisia tridentata Nutt. subsp. wyomingensis Beetle & Young) rangeland have been invaded by medusahead (Taeniatherum caput-medusae [L] Nevski), an exotic annual grass that degrades wildlife habitat, reduces forage production, and decreases biodiversity. Revegetation of medusahead-invaded sagebrush plant communities is necessary to restore ecosystem...
It has recently been proposed that the cost of rehabilitating medusahead (Taeniatherum caput-medusae [L.] Nevski)-invaded
rangelands may be reduced by concurrently seeding desired vegetation and applying the preemergent herbicide imazapic.
However, the efficacy of this ‘‘single-entry’’ approach has been inconsistent, and it has not been compared to the multiple-entry
approach...
Western juniper (Juniperus occidentalis ssp.
occidentalis Hook) encroachment into mountain big sagebrush
(Artemisia tridentata spp. vaseyana (Rydb.) Beetle)
steppe has reduced livestock forage production, increased
erosion risk, and degraded sagebrush-associated wildlife
habitat. Western juniper has been successfully controlled
with partial cutting followed by prescribed burning the next
fall, but the...
