Park & land designation reference
A quick legend for the federal and state land categories Snoflo tracks. Each designation comes with different rules around access, recreation, and resource extraction.
- National Park
- Large protected natural areas managed by the federal government to preserve significant landscapes, ecosystems, and cultural resources; recreation is allowed but conservation is the priority.
- State Park
- Public natural or recreational areas managed by a state government, typically smaller than national parks and focused on regional natural features, recreation, and education.
- Local Park
- Community-level parks managed by cities or counties, emphasizing recreation, playgrounds, sports, and green space close to populated areas.
- Wilderness Area
- The highest level of land protection in the U.S.; designated areas where nature is left essentially untouched, with no roads, structures, or motorized motorized access permitted.
- National Recreation Area
- Areas set aside primarily for outdoor recreation (boating, hiking, fishing, often around reservoirs, rivers, or scenic landscapes); may allow more development.
- National Conservation Area (BLM)
- BLM-managed areas with special ecological, cultural, or scientific value; more protection than typical BLM land but less strict than Wilderness Areas.
- State Forest
- State-managed forests focused on habitat, watershed, recreation, and sustainable timber harvest.
- Bureau of Land Management (BLM) Land
- Vast federal lands managed for mixed use -- recreation, grazing, mining, conservation -- with fewer restrictions than national parks or forests.
