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
