The Munnar – Udumalpet road SH 17 passes through the sanctuary for 16 km and divides it into nearly equal portions. Average annual rainfall is only 500 mm, spread over about 48 days, because it is in the rain shadow region of the southern Western Ghats.[3]
The altitude ranges from 400 meters (1,300 ft) at east end of the Chinnar River to 2,522 meters (8,274 ft) at Kumarikkal Mala peak. Other major peaks in the sanctuary are Nandala Malai 2,372 meters (7,782 ft), Kottakombu malai (2,144 meters (7,034 ft)), Vellaikal malai (1,863 meters (6,112 ft)) and Viriyoottu malai 1,845 meters (6,053 ft). In contrast, Anamudi peak 2,695 metres (8,842 ft), located 23 kilometers (14 mi) away in the adjacent Eravikulam National Park, is the highest peak in South India.[citation needed]
The Chinnar and Pambar rivers are the major perennial water resources in the sanctuary. The Chinnar originates near Kumarikal Malai, follows the interstate boundary along the northwest edge of the sanctuary for 18 km and becomes the Amaravati River in Tamil Nadu.
The Pambar River originates in the Anaimudi Hills and is joined by seasonal rivulets and a few perennial streams originating from sholas in the upper reaches. It traverses the Turner’s Valley in Eravikulam National Park and flows down into the sanctuary through the Taliar Valley between Kanthalloor and Marayoor villages and eastwards through the sanctuary. It joins the Chinnar River at Koottar. The Thoovanam water falls lie deep within the sanctuary on the Pambar River. This cascade is a major tourist attraction. The Chinnar, Pambar, Kabani and Bhavani are the only rivers of the 44 in Kerala that flow eastwards.[citation needed]
Settlements and crops
There are 11 tribal settlements inside the Chinnar WLS, each is well demarcated by temporary stone walls. The main inhabitants are Muthuvas and Pulayars. Cultivation of maize, ragi and lemongrass is practiced in the settlements. The Mudhuvas carry out small scale ganja cultivation for their religious purposes.[6]
Senior officials of the Ministry of Environment and Forests (India), Principal Chief Conservators of Forests of Kerala, Tamil Nadu, Andhra Pradesh and Karnataka, together with other senior forest officials of these states and the Union Territory of Pondicherry, met at Thiruvananthapuram on 3 and 4 November 2006 and resolved several mutual issues concerning conservation and protection of forests and wildlife of the region.
A regular conference of the forest ministers and forest officials of the southern states is held once a year, in rotation in each state.[11]
