Evan Rehm

I have been very fortunate to have lived all over the US and world pursuing my passion of biodiversity conservation and ecological research. I completed my undergraduate degree at Penn State University and my MS degree at the State University of New York at ESF. After finishing these degrees, I spent several years living and working abroad as an avian field technician including in South America, Australia, Southeast Asia, Puerto Rico and the Northern Mariana Islands. I returned to complete my PhD at Florida International University in Miami FL but split my time at my field sites outside of Cusco, Peru. My research focused on the upslope migration of Andean cloudforest in response to climate change. I then completed two post-doctoral research positions at Colorado State University and UC Santa Barbara but was based in the Pacific Island systems of the Northern Mariana Islands and Hawaii. In both systems I researched how invasive species (e.g. snakes, grasses) have negative impacts on native forest conservation and restoration. In Tennessee, I continue this work investigating how climate change and invasive species have negative impacts on local communities including eastern deciduous forest and southeastern grasslands.
