Research Interests:

Dr. Porensky's research focuses on balancing livestock production with conservation and restoration in semi-arid rangelands. Her broad research interests include plant community ecology, plant-herbivore interactions, landscape ecology, and restoration ecology.

Current questions include: 

How do fire and sagebrush coexist in the northern Great Plains, and what management strategies will promote sustainable coexistence

  • How do fire, grazing, and restoration impact annual brome invasion and wildlife conservation in the northern Great Plains?
  • Can we use field-based data and high resolution remote sensing to enhance current state-and-transition models for complex ecosystems located in the Great Basin--Great Plains ecotone?
  • Can native greenstrips or targeted grazing be used to break the cheatgrass-fire feedback cycle in the Great Basin?
