Answer 1

Earlier it was under the reign of the Pandayas in 12th century a dam named Mullaperiyar was constructed across the west flowing river Periyar. As a result, it created an artificial lake in the area which today stands at the centre of the sanctuary, enhancing its beauty to greater extents. With the creation of this lake, the landscape and the features of the valley changed drastically.

During the 18th and 19th centuries, the reserve was the hunting ground of the Travancore kings, which is today the part of most of the Southern Kerala. In 1899, the area was declared as a forest reserve called the Periyar Lake Reserve with an intention of protecting the hunting areas of the kings from the encroachment of tea plantations. Further, in 1934, the lake reserve was converted into a game sanctuary, the Nellikkampatty Game Sanctuary. The Game Sanctuary covered an area of about 500 sq km. In 1950, some more area was added to create the Periyar Wildlife Sanctuary. In 1978, the sanctuary was included in the Central Government initiative to be known as the Project Tiger and was renamed as Periyar Tiger Reserve.

In 1992, the reserve also became a part of Project Elephant when it was launched by the Central Ministry of Environment and Forests to protect the free ranging populations of wild Asian elephants in various states of India.
