Wild Horses in America: Lemons or Lemonade?

Wild Horses in America: Hard Truths And Final Solution

The reason horses do so well in our wild environments is because they belong here. Classifying wild horses as exotics makes sense only to those who are unaware of our continent’s natural history.


For 50-million years, horses and their ancestors coevolved with plants and animals in North America. Horses lived in North America long before so-called “natives” like deer, elk, bighorn, and bison migrated in from Siberia. For eons, North American horses were both abundant and diverse. Pronghorn are the only other large herbivore that evolved on this continent which are still found wild here.


This article outlines a common sense approach to helping habitat by restoring a missing keystone species—wild horses.

Over the course of the past 50-years, since the passing of the 1971 Free Roaming Wild Burro And Horse Protection Act (1971), the management of wild horse herd management areas have undergone many changes resulting from political and economic pressures, which stem from increased consumer/market demands for more (cheap) livestock products.


The challenge

Consumerism is a significant factor influencing the use and management of our natural resources. It’s unreasonable and illogical to expect ranchers to reduce production of affordable livestock products when consumers are clamoring for more.

So at least or until we see a huge spike in vegetarianism in America (and elsewhere), the demands for livestock will continue to rise as they have over the past many decades.

The situation at hand

The result is that today, 50 years since the passage of the 1971 Act, we find that wild horses have been limited — down to about 7% of the grazing on lands that the 1971 Act had set aside for native species American wild horses. And over the same 50-year period, those same lands have been managed by the Bureau of Land Management, arguably to maximize livestock production. As such, management included a significant reduction of apex predators in order to help maximize production via lower livestock losses due to depredation.

The reduction of apex predators in wild horse herd management areas where livestock and wild horses are commingled presents a serious ecological issue and evolutionary injustice for the wild horses being managed in those HMAs. A depleted (or missing) population of the evolved natural predators for wild horses prevents natural selection and population control from occurring. The evolved predators of American wild horses include bears, wolves, mountain lions and coyotes.

Inhibiting or eliminating the evolutionary process of natural selection creates two serious problems for America’s wild horses:

Without their evolved predators living in proper population densities in ecosystems containing wild horses (including HMAs), wild horses will to some extent, depending on available water and forage resources, overpopulate.

Without natural selection, the genetic vigor of wild horses suffers because weak, diseased and genetically defective horses are not culled from the herd by predators. And critically important is the fact that people cannot duplicate this complex evolutionary process, which is unique between a predator and its prey, and has evolved over the millennia. All wild horses in the world originally evolved about 55 million years ago in North America.

The removal/reduction of apex predators from many HMAs has occurred over the course of nearly a century.

The notion held by a few people of suddenly changing course and reintroducing apex predators back into herd areas, which due to powerful economic pressures have evolved into livestock production areas is just not going to fly in the face of the market demands for livestock products by the vast majority of American consumers.

The bottom line

Keeping American wild horses commingled with livestock in herd areas where apex predators have been depleted is perpetrating an ecologic injustice upon native species of American wild horses. It’s simply obtuse management as are the many very costly work-arounds, such as the failed attempts to address the fallout (overpopulation) from a lack of natural wild horse predators, using expensive roundups and contraception.

A modern science-based solution

Relocate and rewild native species of American wild horses where they belong; into the remote wilderness; beyond conflict with livestock enterprises.

We have more than 10 million acres of remote wilderness areas in the western states that are unfit for any livestock production due to difficult mountainous terrain, which adversely affects livestock management logistics, combined with the presence of robust populations of apex predators. Either one or both of these challenges significantly increases costs of livestock production, thereby increasing the cost of goods sold to a point where the end products are not competitively priced.

These same remote areas are nevertheless blessed with abundant water and forage, yet are suffering from almost annual catastrophic wildfire due to the depleted populations of large native herbivores (deer and elk) that had previously inhabited those landscapes.

In the not-too-distant past, these same wilderness areas had proper population densities of deer and elk, which through their grazing maintained ground fuels (grass and brush) to nominal levels year-round, keeping wildfires in the realm of normal wildfire.

There have been serious declines in deer and elk populations in some western states. And over the past decades, that has resulted in the increase of prodigious annually occurring ground fuels (grass and brush), which is now left ungrazed in these very remote wilderness areas. These ground fuels are then subjected to a warming climate, rendering these fuels viable for wildfire sooner in the season, and remaining as dry tinder longer.

Environmental complications and costs for wildfire fuels reduction can be eliminated using wild horses. Wild horses don’t have the complex stomachs of cattle and sheep, which virtually digest all the plant and grass seeds they consume, rendering them unable to germinate.

On the other hand, wild horses pass virtually all the seeds they consume in their droppings, providing a critically important reseeding function for native plants. This evolved symbiosis between wild horses and the flora of the North American continent is especially beneficial for wilderness lands that have been devastated by catastrophically hot wildfire. The droppings of wild horses also contain microorganisms that help fire-damaged soils to recover.

Each wild horse deployed into selected wilderness areas will consume about 5.5 tons of grass and brush annually as they concurrently reseed the landscape, keeping a delicate ecological balance in place.

The resulting wildfire fuels reduction via wild horses is virtually cost-free for taxpayers, and simultaneously solves the livestock-wild horse conflict on lands where livestock production is virtually a permanent enterprise.

An added benefit is taxpayers no longer have to foot the bill for the $100 million-plus in annual costs (BLM spends more than $100 milion annually rounding-up and warehousing wild horses off-range), nor the expensive taxpayer costs related to the draconian sterilization-contraception concepts that some people are motivated to support.

  • Thank you for posting this thoughtful article – it is, for me, the first time I’ve read any article about wild horses which brought together evolutionary history, apex predators, and contemporary pressures (i.e. American consumer pressure for more beef). I do hope many of your readers take the time to both read this article and follow up on reading more about the history of grazing animals on our Western lands. I’ve looked for this type of information – most of which seems to start when sheep and cattle were introduced – a very short history, indeed.

    • Thank you Pat.

      Yes we mistakenly think of natural history over short time frames, and assume animal populations and weather are stable. That is a fault of our educational system in my opinion.

      And we decide what to do without giving equal importance to social, environmental, and economic outcomes as we formulate the actions which we hope will achieve our objectives, visions and missions. The irony is, we mostly want the same outcomes. Considering all these elements every time we make a decision won’t change what we want – but it will transform what we do.

      Thanks again for your comment.

  • This is a very complex issue and that needs to be well acknowledged before any actions towards achieving the given context that the involved people and organizations, takes.
