(b) National Parks
(c) Wetlands declared under Ramsar Convention
(d) Wildlife Sanctuaries
Answer: (b)
Option (b) is correct:
National Parks are among the categories of protected areas in India where local people are not allowed to collect and use biomass. National Parks are formed by the State or central Legislature. A national park cannot be downgraded to a sanctuary. National Park is an area which is strictly reserved for the betterment of the wildlife & biodiversity, and where activities like developmental, forestry, poaching, hunting and grazing on cultivation are not permitted. In these parks, even private ownership rights are not allowed. Their boundaries are well marked and circumscribed.
Additional Information: There are 104 existing national parks in India covering an area of 43,716 km2, which is 1.33% of the geographical area of the country (National Wildlife Database, Dec. 2020).
