Nearly half of the area occupied by sagebrush (Artemisia spp.) ecosystems before European-American settlement has been lost due to conversion to other land cover types, and agriculture, urbanization, and industrial development. Thus, conservation and proper management of these ecosystems has been a priority, especially following the recent listing review of greater sage-grouse (Centrocercus urophasianus). An updated review of mountain big sagebrush (Artemisia tridentata subsp. vaseyana) (Innes 2017) is now available from the Fire Effects Information System (FEIS). This research brief summarizes the  Fire effects information from the FEIS species review regarding the biology and ecology of mountain big sagebrush, how fire affects it, and how mountain big sagebrush responds to fire.
