National parks are natural environments that provide habitats for a wide range of flora and fauna and are protected by law. They are areas of great importance for biodiversity conservation, research, and recreation. Aside from the official term "national park," there are several other words that describe similar protected areas. These include nature reserves, wildlife sanctuaries, game reserves, and conservation areas. Each of these terms is used to describe an area protected for different ecological purposes. Nature reserves, for instance, are protected to maintain and preserve the natural ecosystem, while wildlife sanctuaries focus on the protection of animal species. Game reserves protect animal species for the purpose of hunting and conservation areas are designed to protect both flora and fauna.
