As of 2026, the 777 Bison Ranch in South Dakota maintains a thriving herd of approximately 1,500 DNA-tested bison. The ranch, located near Rapid City, operates as a grass-fed cow/calf operation and is a leader in regenerative agriculture. Their management focuses on "holistic grazing," which uses the bison to improve soil health and increase native plant diversity across thousands of acres. By following low-stress handling techniques inspired by Dr. Temple Grandin, the ranch ensures the well-being of the animals while producing high-quality, sustainable bison meat. The number fluctuates slightly with seasonal calving and sales, but the core population remains stable as part of their commitment to maintaining a robust, productive herd that mimics the natural behavior of the Great Plains' original inhabitants.
