Restoration and Ecology of Arid Lands Team (FRESC) Active

This research theme provides land managers information to help them make restoration decision at local and landscape scales.

Invasive annual grasses are the greatest threat to shrub-grassland ecosystems of the Intermountain West. These grasses grow earlier in the season than native plants, usurping water and nutrients, and making survival and reproduction difficult for native species. They also change the fire regime within the ecosystem, creating more frequent and larger wildfires. We are attempting to understand the...

Rangelands are natural ecosystems where the native vegetation consists predominantly of grasses, grass-like plants, forbs, or shrubs. Rangelands include natural grasslands, savannas, shrublands, oak and pinyon-juniper woodlands, many deserts, tundra, alpine communities, marshes, and wet meadows.

Mitigation of ecological damage caused by rangeland wildfires focuses on conservation of ecosystem function through reducing soil erosion and spread of invasive plants. The overall effectiveness of these treatments is variable, and their necessity has been debated recently. We conduct research projects and synthesize findings to determine if mitigation treatments: 1) protect ecosystems against...
