Oh, Deer! The Problem of Roads as Barriers to Deer Migrations and Movements in Wyoming
By Corinna Riginos
October 5, 2017
Join us for the October Draper Natural History Museum Lunchtime Expedition lecture. Dr. Corinna Riginos presents Oh Deer! The Problem of Roads as Barriers to Deer Migrations and Movements in Wyoming.
Western Wyoming is home to some of the longest distance and most intact ungulate migration routes in North America. Along these migration routes, however, animals face numerous challenges as they come into contact with human development, including roads. Roads cause considerable stress to animals attempting to cross them, and animals often get hit by vehicles—posing a threat to both wildlife populations and human safety. In other cases, roads can create a complete barrier—truncating animals’ migration and movement corridors. As human development and traffic volumes increase, it is important to understand and mitigate the effects of roads on ungulate movements.
In this talk, Dr. Corinna Riginos presents her research on the relationship between mule deer migration and movement patterns and roads in Wyoming. Together, these findings suggest ways to prioritize measures to reduce wildlife-vehicle collisions and improve deer habitat connectivity in Wyoming. Mitigating the effects of roads on wildlife requires a multi-faceted approach that takes into account biology, human behavior, and economic factors. Although roads present a considerable challenge to wildlife, their impacts can be reduced with thoughtful and targeted actions.
About our speaker
Riginos is a Research Associate at the Northern Rockies Conservation Cooperative and an Adjunct Associate Professor at the University of Wyoming and is based in Jackson, Wyoming. Her research focuses on wildlife-habitat interactions and spans topics including road ecology, rangeland restoration and management, African savanna ecology, and the impacts of invasive species, climate change, and land-use change on natural systems. She has published more than thirty scientific papers and maintains active research and outreach programs in Wyoming and in Kenya. Riginos earned her bachelors degree in Environmental Science from Brown University and her PhD in Ecology from University of California-Davis. In 2015, she was named an Early Career Fellow by the Ecological Society of America in recognition of her contributions to the field of ecology.
Draper Natural History Museum Lunchtime Expeditions are supported in part by Sage Creek Ranch and the Nancy-Carroll Draper Foundation.
Join us the first Thursday of each month April through December for a Lunchtime Expedition! These free lectures, supported in part by Sage Creek Ranch, explore a variety of natural history subjects and issues. Lectures take place at 12:15 p.m. and are free and open to the public.
