Research

The Rangeland Research Institute provides researchers with opportunity to conduct a wide range of short- and long-term research projects focused on providing a solid scientific foundation for the sustainable management of rangelands.

We support research that combines expertise and approaches from a variety of academic disciplines and addresses issues related to the competing demands of ecosystem conservation and resource use, including energy exploration and extraction, grazing, water management, wildlife management and biodiversity conservation, and sustainable landscape management.

Effects of defoliation and soil moisture level on methane production and oxidation in soils of the Mattheis Research Ranch

Rangelands are a significant global sink for atmospheric methane, however, little is known about the effects of grazing on the production and oxidation of this greenhouse gas. Dr. Chang and co-investigator Dr. Zhiping Wang (Institute of Botany, Chinese Academy of Sciences) will examine the rates of methane production and oxidation in soils under various defoliation and watering treatments at the Mattheis Research Ranch. For this project, the effects of grazing under different management systems are simulated by defoliating experimental plots at high intensity and low frequency, high intensity and high frequency, and low intensity and high frequency. Results from this project will provide insights about the effects of grazing management on emissions of methane from rangeland soils.
