Why this resource exists, who built it, and how we approach a debate where almost everyone has already made up their mind.
Wild horses are one of the few topics in contemporary American politics where genuine bipartisan consensus exists — and that consensus is part of the problem. That agreement is largely urban, built on the image of the free-running mustang rather than any firsthand knowledge of what an overpopulated herd does to a watershed, a grassland, or the horses themselves. This is not a left versus right divide. It is a rural versus urban one. The people furthest from the land are making the decisions about it — and the ranchers, range riders, tribal members, and land managers who live with the consequences have learned to stay silent. Those who have spoken publicly have faced coordinated harassment campaigns, threats to their livelihoods, and in documented cases, death threats. This is not hyperbole. It is why so many of the sources in this repository are anonymous. On tribal lands, feral horse overpopulation operates outside federal jurisdiction entirely, largely invisible to a public debate that is already missing most of the picture.
Steppelands Foundation built this repository to change that. Drawing from government data, peer-reviewed science, legislative history, and firsthand knowledge from ecologists, biologists, tribal members, ranchers, and land managers on the ground, it is a living archive of what the evidence actually shows — including where it complicates our own position. It is continuously updated as the policy landscape evolves.
What you will find here: a documented history of wild horse legislation, current population and cost data, an annotated library of primary sources, profiles of every major organization involved in the debate, curated news coverage, and firsthand accounts from the people closest to this issue.
Fertility control, adoption, managed gathers, and processing all exist on a spectrum of options that the evidence weighs differently depending on scale, cost, and ecological context. Our goal is to put that full picture in front of anyone willing to look at it honestly.
Steppelands Foundation is a 501(c)(3) nonprofit focused on the intersection of working lands, conservation policy, and cross-cultural exchange between the American West and Central Asia. We work at the ground level — with ranchers, land managers, and tribal communities — on issues where land use, ecological health, and federal policy collide.
This site is maintained by Steppelands as an open educational resource. It is not funded by any advocacy organization, government agency, or commercial interest. We do not solicit donations through this portal. We do not exclude sources that complicate our position. Our only interest is in what the evidence actually shows.
We believe that wild horse management must be grounded in ecological science, fiscal reality, and the lived experience of people on the land. We support a full spectrum of management tools — fertility control, adoption, managed gathers, and in appropriate contexts, commercial processing — evaluated against what the evidence shows in each specific situation.
Land managers, range riders, tribal members, and ranchers who speak publicly about the reality of horse overpopulation on their allotments and tribal lands have faced harassment campaigns, threats to their grazing permits, and personal threats. We take that seriously. Where sources have asked for anonymity, we have protected it. Their publisher is known to us.
Every claim in this portal is traced to a primary source — government data, peer-reviewed science, or legislative text. We annotate secondary sources for what they show and what they miss. Advocacy materials from all sides are included, identified as such.
The science on horse overpopulation is not uniformly supportive of any single management approach. Where evidence challenges our own position, we include it, annotated honestly. A resource that only includes sources that confirm its conclusion is not a resource — it is a brief.
This portal does not advocate for a single answer. Fertility control, adoption, managed gathers, and processing are all on the table. The evidence weighs them differently depending on herd size, range condition, cost, and ecological context. We present that evidence and let it speak.
