Tremaine Gregory

Conservation Biologist
B.A., Bowdoin College, M.A. and Ph.D., Kent State University

Tremaine (Tremie) Gregory is a conservation biologist at the Smithsonian Conservation Biology Institute's Center for Conservation and Sustainability. Her work focuses on the impacts of hydrocarbon development activity on wildlife in the Peruvian Amazon and methods to mitigate such impacts. Currently, she studies the impacts of the construction of an exploratory natural gas well on everything from terrestrial mammals to herbaceous vegetation.

Gregory recently investigated the impact of the construction of a natural gas pipeline on arboreal mammals. She pioneered methods with arboreal camera trapping to test the effectiveness of natural canopy bridges over a pipeline right-of-way in mitigating forest fragmentation. Her findings could help improve best practices in pipeline construction across the Amazon to reduce impacts on arboreal wildlife.
Previously, Gregory engaged in studies in the tropical forests of Ecuador, Nicaragua and Colombia and performed her graduate research in Suriname. She earned her master’s degree in 2006 with a thesis exploring niche divergence of two species of Pitheciine monkeys: bearded and white-faced sakis. She completed her doctorate in 2011, focusing her research on the spatial and feeding ecology and male-affiliative social behavior of bearded sakis. Gregory began working at the Smithsonian Conservation Biology Institute as a postdoctorate fellow in 2011, and became a research scientist in 2013.
Gregory is passionate about developing effective solutions to real world conservation problems. She values opportunities to inform governments and industry with her research, identifying best practices that will provide broad-scale conservation outcomes in the world’s precious tropical forests.
