Abstract:

More than half the total acres (381,727 acres) burned in Nevada during 2012 occurred in sage grouse (Centrocercus urophasianus) Preliminiary Priority Habitat (M. Boomer,) personal Communication, 2013), an alarming fact for a candidate threatened or endangered species.  Preliminary Priority Habitat is defined by the Bureau of Land Management (BLM) as having the highest conservation value to maintaining habitat, brood-rearing, winter range, and important movement corridors.  Burning sagebrush (Artemisia sp.) communities does not generally benefit sage grouse due to the reduction or elimination of sagebrush cover, which can take decades to more than a century to recover.  Fires can be particularly detrimental to thequality of sage grouse habitat when invasive annual grasses are present prior to the fire and respond well or expand after fire.  Furthermore, it has been suggested that larege, frequent fires, like those occuring on Squaw Valley Ranch, may lead to the extinction of sage gruse.  With the continual threat of large fires is sage grouse habitat, it is imperative that cost-effective tools, such as properly managed cattle grazing, are available and utilized to reduce fire frequency, severity, continuity, and size.
