Fire-Grazing Interactions in Kenya
I continue to examine grazing-fire interactions in the Laikipia savannas of Kenya. In the spring of 2013 I burned a series of 18 small plots in collaboration with Truman Young from U.C. Davis and Duncan Kimuyu from University of Nairobi (funded in part by a National Geographic Grant). During the summer of 2013 and 2014 I taught BIOL 375 Conservation Biology and Research Methods in Savannas, a class for Goshen College and Kenyan undergraduates to jointly explore the conservation opportunities in Kenyan savannas. My research and the course is based at Mpala Research Centre in Laikipia, Kenya.
Recent work with four students in 2016 led to a paper addressing the role that fire plays restructuring ant communities which reside on Acacia trees. This is particularly relevant as ants play vital roles in defending the trees against elephant herbivory.
Tallgrass Prairie Grazing Project
In the summer of 2016, we partnered with a local CSA, Blue Heron Farms, to examine the effects of cattle grazing on tallgrass prairie plant communities at Merry Lea. The project seeks to understand whether using tallgrass prairies in grassfed beef operations can be economically viable while simultaneously serving to sequester carbon dioxide.
