The Wild Horses of Theodore Roosevelt National Park
As of March 2026, there are 196 wild horses that call the park home. Note: Birth order numbers have been added to each horse to help decipher the park’s roundup reports.
Three important things to know about the wild horse herd in Theodore Roosevelt National Park:
- This is an older herd, as you can see by the photos below. There is a mare born in 1999 still living and roaming free in the Park.
- TRNP performed a horrific roundup October 13-16, 2024. The initial intent was to hand inject ALL of the mares with GonaCon.
- This herd has repeatedly been treated with GonaCon and the answer to the question on how much of a reproductive herd we actually have remains to be seen.

The Eldest
of the Herd
The horses listed above that were born between 1998-2006. They are between the ages of 15-23 years of age. The sad reality is that within the next 5 years, we will say some sad goodbyes to most, if not all of these horses.
4 of these horses: Mare Winter, Stallion Cloud, Mare Blondie, and Mare Diamond have NO offspring of their own left in Theodore Roosevelt National Park.
An additional 7 of these horses only have offspring because of Mother Nature: Covid, drought, wildfires, etc., that have held off the usual captures of the young horses from this herd. Those horses are: Stallion Brutus, Mare Little Gray, Stallion Coal, Stallion Georgia’s Boy, Mare Mist, Mare River and Mare Ember’s Girl.

The Wild Horses of TRNP Born in 2014
What you should know about this time period in The Park.
The last big round up in TRNP happened in 2013. Around that time, TRNP also got a new wildlife biologist (Blake McCann) who has since incorporated the low stress captures and the irresponsible use of GonaCon being used today as well as targeting all the young horses for removal.

Grady
The only horse born in 2015 still roaming free in TRNP.
In 2014, there were no horses captured in Theodore Roosevelt National Park. That changed in 2015. Every horse born in 2015 was eventually captured and sold, with the exception of one horse – Stallion Grady. Grady was able to avoid capture because his band’s territory was deep in the center of TRNP. The terrain of the badlands tends to get more rugged as you venture off the main road. This makes it hard for the capture team to maneuver through that terrain to capture horses.

Wild Horses Born in TRNP in 2016
A sad year of capture, removal, and sale.
What you need to know about 2016
In 2016, there were 46 live births in TRNP.
Sadly, 4 of those babies did not survive.
Of the 42 horses that thrived that year, only the following 3 were not captured and sold and remain in TRNP today. The 3 that were left, the same as Grady, remained because the terrain in the area where their bands were in was too rough to attempt their capture.

A History-Changing Discovery
2017 Foals Prove Ancient North American Ancestry
Of the 30 foals born in 2017, only 2 were not captured and sold. This is why.
In 2017, because of the results of mitochondrial DNA research, two fillies born in 2017 were spared from being captured and auctioned off like the rest of their 2017 counterparts : 2017 Filly Perdita (Pretty Girl x Red Face) and 2017 Filly Aurora (Dawn x Brutus).
The mitochondrial DNA research on these TRNP horses show that they share female ancestry with Asian, middle East, and Italian horse DNA. That sequence follows the migration patterns of humans and animals.
This proves that the starting point for horses is and will always be the North American continent and that proof is right here within the DNA of these two beautiful mares that currently still call TRNP home.

2018 Foals
TRNP welcomed 28 new foals in 2018. Sadly 8 foals “failed to thrive”. Of the 20 foals that did thrive, only 2 remain in the park today: Mare Patience and Stallion Cagney. Patience and Cagney were part of the same band as Grady was in 2015. The rugged terrain and the location of the band is the only reason that these two were not captured and sold like the rest of the 2018 babies.

2019 Foals
36 babies were born in 2019. Sadly 10 “failed to thrive”. In the fall of 2019, 9 babies, age 4 months to 6 months old, were captured and sold. Because of the COVID pandemic in 2020 and the extreme drought conditions in 2021, no other 2019 babies have been removed – YET. There are still 16 “babies” from 2019 currently living in TRNP.
