Understanding the Role of Perennial Grasses in Sagebrush Establishment — Damaris Chenoweth

I recently returned from Southwestern Wyoming where I collected data over five weeks. The undisturbed Wyoming big sagebrush of the Jonah Field is dotted by disturbed plant communities, in which perennial grasses often dominate during the early stages of plant community recovery after well pad establishment. When well pads are reclaimed—the practice of returning soil Read more about Understanding the Role of Perennial Grasses in Sagebrush Establishment — Damaris Chenoweth[…]

Mapping Resource “Neighborhoods” of Big Sagebrush — Damaris Chenoweth

Once covering nearly half of the American West, sagebrush ecosystems are now among the most threatened in North America.  In the past century, climate change, human land use, shifting disturbance regimes, and the introduction of invasive plants have driven significant loss, fragmentation, and modification of sagebrush communities.  As part of my research, I will characterize Read more about Mapping Resource “Neighborhoods” of Big Sagebrush — Damaris Chenoweth[…]

Simulating the Recovery of Big Sagebrush Communities from Disturbances Due to Oil and Gas Extraction

At well pads—areas developed for oil and gas drilling—both the vegetation and topsoil are completely removed. After drilling infrastructure is installed, these areas are reclaimed, meaning the topsoil is then replaced, and the areas are seeded with various mixes of species. Despite reclamation efforts, big sagebrush communities have an extremely hard time returning to a Read more about Simulating the Recovery of Big Sagebrush Communities from Disturbances Due to Oil and Gas Extraction[…]

Climate Vulnerability in the Crown of the Continent

UHPSI students collaborated with U.S. Fish and Wildlife Service to assist with a Landscape Conservation Design (LCD). The Crown Managers Partnership created this design to model spatially-explicit future conditions in the Crown of the Continent ecosystem, which encompasses parts of Montana, Alberta and British Columbia. As a preliminary step in LCD development, our student research Read more about Climate Vulnerability in the Crown of the Continent[…]
