USGS Press Release: Plant age drives mortality, reproductive success and population dynamics

Release Date:

A USGS press release was published today highlighting a paper describing possible limitations of big sagebrush restoration in the American West after wildfires.   

Big sagebrush is very sensitive to fire and does not resprout and this type of disturbance like some other shrub species can. Restoration of this species is notoriously difficult and expensive. USGS scientists at the Southwest Biological Science Center and   the Forest and Rangeland Ecosystem Science Center conducted research on 531 burned sites that contained big sagebrush in an attempt to understand why it is so difficult to reestablish this species after a fire.

Mountain big sagebrush - or Artemisia tridentata ssp. vaseyana - is a sub-species of big sagebrush that is found in primarily at higher elevation and colder, drier sites between the Rocky Mountains and the Cascades and Sierra Nevada.
