Conservationists at Theodore Roosevelt National Park in North Dakota are taking a modern approach to managing the country's largest free-roaming bison herd. For the first time, helicopters will be used to round up over 700 animals that roam freely across more than 2 million acres of land. The move aims to minimize ecological strain on the environment while promoting genetic diversity among the animals.
The annual operation is crucial for maintaining the health and size of the bison herd. By conducting the roundup in the fall, when temperatures are cooler, officials hope to reduce heat-related stress on the animals. This method also allows them to monitor the movement of the bison more easily and direct their flow towards corral installations.
Once rounded up, resident veterinarians will evaluate each animal's health, genetic makeup, and demographics such as age and biological sex. The bison are then sorted accordingly and either released back into the park or donated to tribal lands. This year, around 400 animals are expected to be relocated to tribal nations in an effort to boost Indigenous community connections and diversify local wildlife.
The use of helicopters for this operation has several advantages. From a distance, it reduces the risk of injury to both humans and animals. Additionally, flying over the terrain provides officials with a clearer view of the bison's movement patterns and allows them to make more informed decisions about their relocation.
