2024 Black Mountain HMA Wild Burro Gather - Gather Complete

The Bureau of Land Management’s Colorado River District, Kingman Field Office, is conducting a burro gather within the Black Mountain Herd Management Area.

The gather will begin on or around January 8, 2024, utilizing the national drive trap contract; using a helicopter-assisted method. 

This drive trap gather is expected to take about eight weeks. All gather operations will be overseen by the BLM Colorado River District, Kingman Field Office, and Arizona State Office. 

All excess wild burros identified for removal will be transported to the Florence Off-Range Wild Horse and Burro Corrals, located in Florence, Ariz., and to the Ridgecrest Regional Wild Horse and Burro Corrals near Ridgecrest, Calif. where they will be checked by a veterinarian and readied for the BLM’s wild horse and burro Adoption and Sale Program. 

Purpose of Gather:

The purpose of the gather is to address an overpopulation of wild burros within the Black Mountain Herd Management Area (HMA) to achieve a thriving natural ecological balance, alleviate deterioration of the rangeland as well as to address public safety and private property concerns. The gather will also address human health and safety concerns within the local area related to vehicle collisions with burros on the roadways and damaging private property. For these reasons, local communities in Mohave County have requested that the BLM address the wild burro overpopulation in the Black Mountains. 

The Black Mountains HMA has an estimated population of 1,925 wild burros — the largest wild burro herd on public lands, as of November 2023. The appropriate management level (AML) for the Black Mountain HMA is 478 wild burros, set in the Black Mountain Ecosystem Management Plan.

Details of Gather:

The BLM plans to gather and remove up to 1,000 excess wild burros from the Black Mountain Herd Managment Area. In addition, the BLM plans to treat approximately 100 jennies (if they are gathered) with Porcine Zona Pellucida (PZP). The BLM will hold the selected females at the Kingman temporary staging facility until completion of their respective fertility control treatment and release them back on to the range.

The gather will begin on or around Jan. 8, 2024, utilizing the national drive trap contract; using a helicopter-assisted method. 

This drive trap gather is expected to take about eight weeks. All gather operations will be overseen by the BLM Colorado River District, Kingman Field Office, and Arizona State Office. 

The Black Mountain Herd Area (HA) covers nearly 1.1 million acres of public, state, tribal, and private lands in Mohave County in northwestern Arizona. The Appropriate Management Level (AML) for the Black Mountain HMA is 478 wild burros. As of March 2023, the estimated population was approximately 1,674 wild burros, which does not include the foals born this year. The current population estimate, including the 2023 foal crop, puts the HMA at approximately 1,447 wild burros over AML. The most recent gather was completed in March 2023. 

All excess wild burros identified for removal will be transported to the Florence Off-Range Wild Horse and Burro Corrals, located in Florence, Ariz., and to the Ridgecrest Regional Wild Horse and Burro Corrals near Ridgecrest, Calif., where they will be checked by a veterinarian and readied for private placement through the BLM’s wild horse and burro Adoption and Sale Program. 

Public Observation:

Public viewing will be available in a limited capacity. Locations and availability of public viewing may change daily throughout the gather. Media and members of the public will coordinate with the gather Public Affairs Specialist Dolores Garcia to receive details such as meet-up times and locations. Four-wheel drive and high clearance vehicles will be required.

Adoption Information:

Animals removed from the Black Mountain HMA will be made available for adoption or purchase at Florence Wild Horse and Burro Training and Off-range Corral and the Ridgecrest Regional Wild Horse and Burro Corrals near Ridgecrest, California through the Wild Horse and Burro Adoption and Sales Program.

Background:

The BLM manages free-roaming wild horses and burros on public lands as part of its multiple-use mission, with the goal of supporting healthy wild horses and burros on healthy public rangelands. The BLM is responsible for determining and maintaining appropriate management levels (AML) for each herd and works to achieve that population target through a variety of management processes, including limiting reproduction in some herds through the use of birth control and gathers that remove excess animals from the range.
