1. It the smallest species of wild pig in the world 2. It is considered as an indicator species as its presence reflects the health of its habitat Which of the statements given above is/are correct?Solution
Recently, eighteen captive-bred pygmy hogs were released in western Assam’s Manas National Park and Tiger Reserve It is one of the very few mammals that build its own home, or nest, complete with a ‘roof’ It is an indicator species as its presence reflects the health of its primary habitat Currently, the viable population of this pig in the wild is in the Manas Tiger Reserve in Assam It is the smallest and rarest species of wild pig in the world
