National parks are protected areas of land set aside by governments for conservation, recreation, and environmental education. These parks are typically designated for their natural, cultural, or historical significance and are managed by governmental bodies to ensure their preservation and enjoyment by visitors. National parks often contain diverse ecosystems, wildlife, and geological features, making them important sites for research and study in fields such as ecology, biology, geology, and environmental science. Researchers in national parks may study topics such as biodiversity, habitat conservation, climate change impacts, and natural resource management. Additionally, national parks serve as outdoor laboratories for scientists, providing opportunities for field research and monitoring of environmental changes over time.
