| Historically, the Sagebrush Sea covered approximately 150 acres in western North America, and was perhaps as large as 243 million acres, spanning parts of 16 states and three Canadian provinces. However, the sagebrush steppe has been reduced in area by as much as 50 percent since European settlement and exotic grasses and weeds now dominate native vegetation across much of the landscape. | ||||

Sagebrush (Artemisia spp.) are among the most widely distributed native plants in the western United States. Aproximately 21 varieties of sagebrush grow from sea level to nearly 12,000 feet and in areas that receive as little as eight inches of precipitation annually. Many varieties of sagebrush are endemic to western North America, including all big sagebrush taxa. Big sagebrush can live to 100 years. | |||
