The hidden potential within soil seed banks

Science Spotlights Posted on: July 31, 2019
Wildfire and other disturbances to plant communities are becoming larger and more frequent across arid lands of the western U.S. Degradation caused by these disturbances affects the ability of these plant communities to deliver important food and shelter to wildlife. Understanding how to predict the presence of native seeds within the soil seed bank, and where there are abundant seeds of invasive species, will help land managers determine the regeneration potential within the seed bank and inform restoration planning to reestablish biodiversity and ecosystem function in disturbed areas.

Dormant seeds in the soil are an important contribution to the regenerative potential of an area. Understanding factors that affect seed bank dynamics in arid regions provides insight into how communities respond to disturbance and environmental change.

Desert Experimental Range

Experimental Forests and Ranges Posted on: September 08, 2015
ed in 1933 by President Herbert Hoover, the Desert Experimental Range has long been a center for cold desert rangeland research. Desert Experimental Range is an internationally renowned site for range ecology education, and in 1976, the United Nations Educational, Scientific, and Culture Organization (UNESCO) designated it a biosphere reserve.

Effect of repeated burning on plant and soil carbon and nitrogen in cheatgrass (Bromus tectorum) dominated ecosystems

Fire has profound effects on ecosystem properties, but few studies have addressed the effect of repeated burns on soil nutrients, and none have been conducted in cold desert ecosystems where invasion by exotic annual grasses is resulting in greater fire frequency.

Cold desert fire and invasive species management: Resources, strategies, tactics, and response

Publications Posted on: December 03, 2009
The cold desert of North America, sometimes referred to as the Intermountain area, is comprised of a western Great Basin section and an eastern Colorado Plateau section. In general, the cold desert receives more than half of its annual precipitation as snow, and because of its more northern latitude or higher elevations, has relatively low average annual temperatures. Snow cover is common and may last for weeks, yet summers can be hot.
