Key Takeaways
-
The resident bison herd managed by American Prairie has surpassed 1,000 animals for the first time in the organization's 20-year history.
-
The reserve currently spans more than 603,000 acres in Montana, working toward an ultimate goal of 3.2 million acres of contiguous wild prairie.
-
The population milestone comes on the heels of a legal victory upholding the herd's grazing access on federal public lands.
A historic resurgence on the Great Plains
In an inspiring achievement for wildlife restoration, the largest private land conservation initiative in the United States has reached a celebrated benchmark. For the first time in its more than two decades of operation, the nonprofit reserve American Prairie has recorded a four-digit bison population, with its latest seasonal calf count bringing the resident herd to 1,016 animals.
Historically, tens of millions of bison shaped the Great Plains before commercial hunting nearly wiped out the iconic species. Today, wild bison represent only a tiny fraction of their historic numbers, and fewer than 10% are managed specifically for conservation. Most existing herds remain confined to small, fenced pastures that restrict their natural movement and genetic resilience. American Prairie seeks to change that dynamic by allowing bison to wander across expansive, contiguous terrain where they can fulfill their vital ecological role as keystone grazers.
The project currently encompasses 603,657 acres across Montana, comprising 167,070 deeded acres alongside 436,587 leased public acres. If designated as a national park, the assembled territory would already rank among the ten largest in the contiguous United States. The milestone follows a vital preliminary legal ruling affirming the herd’s right to graze on federal public allotments under the Taylor Grazing Act. Conservation leaders ultimately aim to assemble a seamless 3.2-million-acre expanse capable of supporting tens of thousands of free-ranging bison.
