Areas within 10 kilometres of protected areas, national parks, and wildlife sanctuaries are referred to as eco-sensitive zones or ecologically fragile areas. In accordance with the Environment Protection Act of 1986, ESZs are declared by the MoEFCC, Government of India. Even areas wider than 10 km can be included in the eco-sensitive zone if there are sensitive connectivity, biologically significant patches, and sensitive corridors in those locations that are essential for landscape linkage. The primary goal of these regulations is to limit the detrimental effects of certain activities on the delicate ecosystem surrounding National Parks and Wildlife Sanctuaries.
