BIWFC SPONSORED SYMPOSIUM at 2022 TWS CONFERENCE

“Fertility Control to Mitigate Conflicts and Manage Wild Horse and Burro Populations on Public Lands in the U.S.”


The BIWFC and The National Wildlife Research Center organized a symposium titled Fertility Control to Mitigate Conflicts and Manage Wild Horse and Burro Populations on Public Lands in the U.S., at The Wildlife Society’s (TWS) 29th Annual Conference held in Spokane, Washington, USA from November 7 – 10, 2022.

Since the passage “Wild Free-Roaming Horses and Burros Act of 1971,” managing America’s wild equids has evolved into a fiscal and political quagmire that is now one of the most critical and complex wildlife management issues in the U.S. today. This session explored public knowledge, values and attitudes about wild equid management, stakeholder perspectives and disputes that impact management decisions, the use of multi-objective modeling as a management decision-support tool, and the role fertility control can play in providing effective, sustainable, and widely accepted alternatives for managing wild equid populations on public lands in the U.S.
