Bald eagle flying over water
April 5, 2019

Since the ban of DDT, bald eagle populations have rebounded to near-historic levels and aircraft strikes have increased since 1998. Wildlife-aircraft strikes are expensive and the large body size of the bald eagle increases the likelihood of aircraft damage and human injury when a collision occurs.

Assessing the world's inland fisheries- Abigail Lynch

Inland fisheries are important contributors to global food security and poverty alleviation. However, there is no standardized method to monitor and assess the status of inland fisheries. The goal of this project is to assess the vulnerability and resiliency of all major inland fisheries globally through the creation of an interactive assessment tool to be used by fisheries managers.
