Erik is a Ph.D. student at the University of Arizona studying the effects of mesquite encroachment into desert grasslands on bird diversity, density, and reproductive success.  His project will lead to a better understanding of the ecological processes that drive grassland ecosystems and contribute to the development of sound management practices. 

Erik participated in the 2016 Science on the Sonoita Plain Symposium and has given a presentation on avian impacts of shrub encroachment at the Research Ranch's Potluck and Presentation events.
