Periyar Tiger Reserve, Thekkady, is an example of nature’s bounty with great scenic charm, rich bio diversity and providing veritable visitor satisfaction. Sprawled over an area of 925 Sq .km., Periyar is one of the 48 tiger reserves in India. Zealously guarded and efficiently managed reserve is a repository of rare, endemic and endangered flora and fauna and forms the major watershed of two important rivers of Kerala, the Periyar and Pamba. Periyar National Park and Wildlife Sanctuary (PNP) is a protected area in the districts of Idukki, Kottayam and Pathanamthitta in Kerala, India. It is notable as an elephant reserve and a tiger reserve. The protected area covers an area of 925 km2 (357 sq mi). 305 km2 (118 sq mi) of the core zone was declared as the Periyar National Park in 1982.

The park is often called the Periyar Wildlife Sanctuary or Thekkady. It is located high in the Cardamom Hills and Pandalam Hills of the south Western Ghats along the border with Tamil Nadu. It is 4 km (2.5 mi) from Kumily, approximately 100 km (62 mi) east of Kottayam, 110 km (68 mi) west of Madurai and 120 km (75 mi) southeast of Kochi.[1]

History

Entrance to the tiger reserve
Periyar Lake

The first official action towards the conservation of wildlife and biodiversity in Kerala was taken in 1934 by the Maharaja of Travancore, Chithira Thirunal Balarama Varma, by declaring the forests around Periyar lake as a private game reserve to stop the encroachment of tea plantations.[2][3] It was founded as Nellikkampatty Game Reserve. It was consolidated as a wildlife sanctuary in 1950 after the political integration of India.

Geography

The misty mountain ranges of the Periyar region

Periyar National Park lies in the middle of a mountainous area of the Cardamom Hills. In the north and the east it is bounded by mountain ridges of over 1,700 m (5,600 ft) altitude and toward the west it expands into a 1,200 m (3,900 ft) high plateau. From this level the altitude drops steeply to the deepest point of the reserve, the 100 metre valley of the Pamba River. The highest peak is the 2,019 m (6,624 ft) high Kottamalai. The Periyar and Pamba Rivers originate in the forests of the reserve.[4] The other prominent peaks within the park are Pachayarmala, Vellimala, Sunderamala, Chokkampetti mala and Karimala.[5] The topography consists of steep and rolling hills which are thickly wooded. The sanctuary surrounds Periyar Lake, a reservoir measuring 26 km2 (10 sq mi) which was formed when the Mullaperiyar Dam was erected in 1895. The reservoir and the Periyar River meander around the contours of the wooded hills, providing a permanent source of water for the local wildlife.

Climate

The temperature varies depending upon the altitude and it ranges between 15 °Celsius in December and January and 31 °Celsius in April and May. Annual precipitation is between 2000 and 3000 mm, about two thirds occurring during the southwest monsoon between June to September. Much of the rest occurs during the northeast monsoon between October and December. Summers are warm with some precipitation in April and winters are cold.

Flora

The park is made up of tropical evergreen and moist deciduous forests, grasslands, stands of eucalyptus, and lake and river ecosystems.[6] There are many hundreds of flowering plant taxa, including about 171 species of grass and 140 species of orchids.[6] The grasses are found in the open grasslands found on the edges of the water body where fire resistant vegetation grows and dense grasses like elephant grass are found. This is the common dining hall of various herbivores.

The forests contain deciduous and semi evergreen trees like teak, rosewoods, terminalias, sandalwoods, jacarandas, mangoes, jamun, tamarind, banyans, sacred fig, plumerias, royal poinciana, kino tree, bamboos, and the only South Indian conifer, Nageia wallichiana.[6] The medicinal gloriosa lily grows in the park. The endemic flora includes Habenaria periyarensis and Syzygium periyarensis.[6]

The park is surrounded by agricultural regions, especially plantations of such crops as tea, cardamom, and coffee.[6]

Timeline

Ecosystem valuation

It is estimated that the Periyar Tiger Reserve (PTR) provides flow benefits worth 17.6 billion rupees (1.9 lakh (190,000)/ hectare) annually. Important ecosystem services included gene-pool protection (7.86 billion), water provisioning to districts of Tamil Nadu (4.05 billion), habitat and refugia for wildlife (3.55 billion), employment generation for local communities (25 million), water purification services to nearby towns and districts (483 million) and recreation value (425 million).
