Gund Graduate Fellow, Rubenstein School of Environment and Natural Resources

Kenna Rewcastle is a PhD student in the Rubenstein School of Environment and Natural Resources where her research investigates the impact of climate change on the functioning of mountain ecosystems. Kenna has experience studying the ecology of mountain ranges around the world, from Southern Greenland to the tropical rainforests of Monte Verde in Costa Rica.

Originally from the Smoky Mountains of East Tennessee, Kenna holds a BA in ecosystem ecology from the University of Tennessee and comes to UVM after a Fulbright Fellowship where she studied reindeer populations and the lichen that they feed on during winter in Sweden for a year.

In her dissertation research, Kenna will connect her research on how the nitrogen cycle is impacted by climate change to the consequences of these changes for forage resources that support livestock and wildlife in mountains. Kenna hopes to pursue a career in environmental policy and resource management following the completion of her PhD.

Kenna’s love for mountains extends beyond her academic research and spills into her every hour of free time when she can be found rock climbing at many of the local crags scattered along the Long Trail or backpacking and camping with friends. She also serves as a Board Fellow on the Green Mountain Club Board of Directors.
