Climate variability, carbon, drought and fire, in arid-semi-arid ecosystems

Science Spotlights Posted on: August 01, 2019
Using the best available science and tools, we can project the effects of today’s management actions on tomorrow’s non-forest vegetation assemblage, carbon, and productivity while considering changing climates. 

Using traditional phenological knowledge

Science Spotlights Posted on: March 29, 2018
This research looks at opportunities to utilize traditional phenological knowledge to support adaptive management of social-ecological systems vulnerable to changes in climate and fire regimes. Integrating phenological knowledge into natural resource stewardship is important in making land management decisions. Indigenous knowledge of seasonal change adds a broader ecological knowledge base in the context of changing and vulnerable social and ecological systems. The knowledge gained from an ongoing relationship with the landscape and ecosystems therein holds potential for conservation, restoration, and adaptation. 

Long-term, landscape patterns of past fire events in a montane ponderosa pine forest of central Colorado

Publications Posted on: December 27, 2016
Parameters of fire regimes, including fire frequency, spatial extent of burned areas, fire severity, and season of fire occurrence, influence vegetation patterns over multiple scales. In this study, centuries-long patterns of fire events in a montane ponderosa pine - Douglas-fir forest landscape surrounding Cheesman Lake in central Colorado were reconstructed from fire-scarred trees and inferences from forest stand ages.

Climate and human influences on historical fire regimes (AD 1400-1900) in the eastern Great Basin (USA)

Publications Posted on: January 12, 2016
High fire activity in western North America is associated with drought. Drought and fire prevail under negative El Niño Southern Oscillation (ENSO) and Pacific Decadal Oscillation (PDO) phases in the Southwest and with positive phases in the Northwest. Here, I infer climate effects on historic fire patterns in the geographically intermediate, eastern Great Basin and seek out evidence of human influence on reconstructed fire regimes.

Chihuahuan Desert grassland responds similarly to fall, spring, and summer fires during prolonged drought

Publications Posted on: March 16, 2015
Land managers frequently use prescribed burning to help maintain grassland communities. Semiarid grassland dynamics following fire are linked to precipitation, with increasing soil moisture accelerating the rate of recovery. Prescribed fires are typically scheduled to follow natural fire regimes, but burning outside the natural fire season could be equally effective and more convenient for managers, depending on their management objectives.
