Research > Grazing Ecology & Management


Current Research

The grazing ecology & management project includes ranch-scale and multi-county assessments to determine best practices for rangeland management. The team works to regenerate soil health and ecosystem function in North American grazing ecosystems.

Project objectives:

  1. Determine the extent that grazing strategies influence key ecosystem services.The team takes into account soil carbon sequestration, soil fertility and stability, water quality, net primary and secondary production, and economic viability of working ranches that contribute to the retention of open space and rural community health in the South Plains.
  2. Determine the extent that different grazing management strategies can be used by livestock producers to restore soil health, ecosystem function, and to mitigate and adapt to alternative climate change scenarios.
