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.
