The Nature Conservancy currently owns and manages more than 16,000 acres in North Dakota. Most of our land is open to the public for outdoor recreation.
We do not maintain trails or facilities at most our preserves nor do we have staff on duty. Please prepare for your visit and take proper precautions by reviewing our Preserve Visitation Guidelines.
