The only person to date that has done any research on the origin of the wild horses in Theodore Roosevelt National Park was Castle McLaughlin. This paper was published in 1989 when Castle was a graduate student at Columbia U in NYC and an interpretive ranger for Knife River Indian Villages NHS (NPS) in Stanton, N.D. Castle has recently retired after 25 years of being a curator at Harvard’s Peabody Museum

Plans for wild horse herd at Theodore Roosevelt National Park range from no change to no horses

The National Park Service is reexamining its management of more than 180 horses for the first time since it adopted an environmental assessment in 1978. Options range from maintaining the current program to allowing the herd to “live out their lives in the park.”

This is a copy of the partnership agreement between North Dakota Badlands Horse (NDBH) and Theodore Roosevelt National Park. The partnership has since been dissolved, but according to NDBH’s website, “NDBH and TRNP have an informal partnership which allows NDBH volunteers to help TRNP staff with the captures, working through the system as Vet preparation, helping with the Vet., helping the Brand Inspector and paying for brand inspection, and loading out horses. NDBH pulls and sends in hair samples for DNA testing.” This is important because if you read through their partnership, you will see the essence of this agreement is that NDBH agreed to help TRNP park management with the capture and sale of the horses. NDBH both partnered with TRNP Park Management to decimate this herd AND continues to profit from the sale of the horses in TRNP.

In 2018, a research paper was released entitled “Genetic Diversity and the origin of the feral horses of Theodore Roosevelt National Park” You can read the entire report here:
