National Preserves are protected areas in the United States that aim to conserve natural resources, wildlife, and cultural heritage. Unlike national parks, they allow for certain activities like hunting, fishing, and grazing, which can help manage the land while still preserving its ecological integrity. These areas are managed by the National Park Service and often feature diverse ecosystems, historical sites, and recreational opportunities. National preserves provide a balance between conservation and public enjoyment, ensuring that both nature and human activities can coexist sustainably.
