A "natural site" refers to a location that is primarily characterized by its natural features, such as landscapes, ecosystems, and wildlife. These sites can include mountains, forests, rivers, and beaches, and they often provide habitats for various species. Natural sites are important for biodiversity and can also serve as recreational areas for activities like hiking, birdwatching, and camping. Many natural sites are protected as national parks or reserves to preserve their ecological integrity. Examples of well-known natural sites include the Grand Canyon, Yellowstone National Park, and the Great Barrier Reef. These areas are valued for their beauty, scientific significance, and cultural heritage.
