History: The Hart Mountain site was established as part of the Joint Fire Science Project to understand the ways to restore sagebrush ecosystems as a result of both juniper expansion and invasive species; each resulting in increased fire frequencies and the conversion of sagebrush shrublands to annual grasslands (http://sagebrushstep.org). In addition to control plots, the site consists of several long-term treatment plots: burned, herbicide application, and physical juniper removal). Treatment and control plots at this site range from 81 to 405 ha, where cheatgrass ranges from being a minor component to being a co-dominate with sagebrush in the plant community. Treatments will be applied in 2007 and follow-up measurements of soils, plants and animals will be made by members of the Joint Fire Science Project team.

Key characteristics: This site is dominated by the three dominant vegetation associations that characterize the basin portion of the basin and range of the Great Basin: sagebrush steppe, invasive annual grassland, and sage-brush juniper steppe.
