The historic Daniels Park bison herd will graze on 150 acres of native prairie within the Highlands Ranch Backcountry Wilderness Area, marking the animals’ return to the region after a 150-year absence. This reintroduction is a collaborative effort between the Highlands Ranch Community Association (HRCA), Denver Mountain Parks (DMP), the Denver Zoo Conservation Alliance, and the Sanctuary Golf Course, according to an HRCA press release.
Why are bison considered essential for grassland restoration?
Bison function as a keystone species, actively shaping the health of the Great Plains ecosystem through their natural grazing habits, according to HRCA. Their presence promotes diverse plant growth, improves soil health, and supports broader wildlife habitats. By mimicking the ecological processes that historically defined Colorado’s landscape, the project aims to increase the resilience of the native prairie. This mirrors successful reintroduction precedents, such as the historic wildlife recovery efforts at Genesee Park in the early 1900s, which also utilized stock from the Denver Zoo Conservation Alliance.

The herd traces its lineage to some of the last wild bison in North America, including bison from Denver Zoo Conservation Alliance that helped establish the Genesee Park herd in the early 1900s. Now, the herd plays an important role in preserving genetic diversity and supporting broader conservation efforts.
How does this project impact local conservation efforts?
The reintroduction serves a dual purpose: ecological restoration and public education. According to the HRCA, the project provides a tangible way for the community to engage with Colorado’s natural heritage. Visitors gain opportunities to learn about the historical relationship between bison, the grasslands, and Indigenous cultures. Shannon Dennison, director of DMP, stated that the project serves as a “powerful reminder” of the results achievable through true partnership, noting that these animals are direct descendants of the herd that helped bring the species back to the state.
What are the long-term goals for the herd?
While the herd will seasonally graze the 150-acre Backcountry Wilderness Area tract, the primary long-term objective is the preservation of genetic diversity. This project supports habitat stewardship, ecological restoration, conservation education and scientific understanding of the role bison play in maintaining healthy grassland ecosystems.

If you plan to visit the Backcountry Wilderness Area to see the bison, check the HRCA website for seasonal access updates. Bison are wild animals; always maintain a safe distance and follow all posted park guidelines to ensure both human and animal safety.
Frequently Asked Questions
- Are the bison dangerous to hikers? Bison are large, wild animals. Park officials advise visitors to remain on designated trails and maintain a significant distance at all times.
- Why were these specific bison chosen? The Daniels Park herd is historically significant and genetically linked to the original conservation herds established by the Denver Zoo Conservation Alliance.
- Will the bison stay in the Backcountry Wilderness Area year-round? No, the HRCA notes that the herd will graze the area seasonally as part of a managed stewardship program.
