Comparison of Medusahead-Invaded and Noninvaded Wyoming Big Sagebrush Steppe in Southeastern Oregon
, 2008 Medusahead (Taeniatherum caput-medusae [L.] Nevski) is an exotic, annual grass invading sagebrush steppe rangelands in the western United States. Medusahead invasion has been demonstrated to reduce livestock forage, but otherwise information comparing ...

Response of sagebrush steppe species to elevated CO\u3csub\u3e2\u3c/sub\u3e and soil temperature [PDF]
, 2005 Elevated atmospheric CO2 may cause long-term changes in the productivity and species composition of the sagebrush steppe. Few studies, however, have evaluated the effects of increased CO2 on growth and physiology of species important to this ecosystem ...

Fire history and western juniper encroachment in sagebrush steppe
, 1999 The recent expansion of juniper into sagebrush steppe communities throughout the semiarid Intermountain West is most frequently attributed to the reduced role of fire, introduction and overstocking of domestic livestock in the late 1800s, and mild and ...

Biochar Effectiveness in Sagebrush Steppe Re-Establishment Post-Fire
With increased wildfire incidences, fire-intolerant sagebrush steppe ecosystems in North America are more at risk of destruction. Sagebrush re-establishment is unpredictable post-fire in semi-arid climates as successful sagebrush growth requires moist ...
