Webinars feature diverse perspectives on new research, the future of corridor protection

The Pew Charitable Trusts, the National Wildlife Federation, and the Theodore Roosevelt Conservation Partnership are co-hosting a series of webinars on wildlife migration issues across the Western United States.

The “Wildlife Migration in the West” forum series brings together biologists who are researching and tracking migrations; state, tribal, and federal entities implementing policies to protect these corridors; and nonprofit organizations working to educate policymakers and the public about science-based strategies to protect migration routes.

Part 1: Telling Migration Stories Through Science

In Part 1 of the series, wildlife scientists did a deep dive into the latest scientific insights of the migration phenomena, sharing new research on how barriers and climate affect animals’ ability to move.
