2025 Three Rivers Complex Bait and Water Trapping Wild Burro Gather
Purpose of Gather:
The objective of the gather is to bring the population closer to the Appropriate Management Level (AML), implement fertility control as well as address nuisance and public safety issues.
Details of Gather:
The gather will use a bait and water trapping method to gather up to 1,100 wild burros from the Alamo, Big Sandy, and Havasu herd management areas, also referred to as the Three Rivers Complex, in northwestern Arizona. The gather will use a bait and water trapping techniques, utilizing BLM’s national bait trap contract. Small corrals, with food and water within them, will be placed in strategic areas and will be removed once operations are complete.
A minimum of 100 female burros will receive fertility control treatment and be returned to the area from which they were removed.
The operation is planned through November 2025 or may conclude sooner if the gather goal is reached.
Public Observation:
Due to the nature of the gather, there will be no public viewing opportunities. Updates will be provided via the BLM website and social media.
Adoption Information:
Animals which have been gathered will be transported to off-range corral facilities in Utah and Arizona for adoption and private placement.
Some of the burros gathered will be made available for adoption or purchase at Florence Wild Horse and Burro Training and Off-range Corral through the Wild Horse and Burro Adoption and Sales Program.
