Restoration of exotic annual grass-invaded rangelands is needed to improve ecosystem function and services.
Increasing plant species richness is generally believed to increase resistance to invasion and increase desired
vegetation. However, the effects of species richness and individual plant life forms in seed mixes used to restore
rangelands invaded by...
Declining greater sage-grouse populations are causing concern for the future of this species across the western United States. Major
ecosystem issues, including exotic annual grass invasion and conifer encroachment, threaten vast acreages of sagebrush rangeland
and are primary threats to sage-grouse. We discuss types of problems facing sage-grouse habitat and...
The spread of medusahead across the western United States has severe implications for a wide range of ecosystem
services. Medusahead invasion reduces biodiversity, wildlife habitat and forage production, and often leads to
increased fire frequency and restoration costs. Medusahead is problematic in the Intermountain West and California
Annual Grasslands. The...
Fire has largely been excluded from many mountain big sagebrush communities. Managers are reluctant to
reintroduce fire, especially in communities without significant conifer encroachment, because of the decline in sagebrush-associated
wildlife. Given this management direction, a better understanding of fire exclusion and burning effects is
needed. We compared burned to...
African rue is a poisonous, perennial forb that readily invades salt-desert shrub and sagebrush-steppe rangelands. Information detailing options for integrated management of African rue is lacking. To date, a few studies have researched the efficacy of different herbicides for controlling African rue, but none have investigated integrated approaches to its...
