Legal Boundaries

The erstwhile Chinnar Reserve was notified as a Sanctuary in 1984. The original notification of the Chinnar Reserved Forest dates back to 1942 and the boundaries follow a jumble of cairn numbers and survey numbers. At present the boundaries are fully demarcated but in certain areas like Njavala-Ollavayal, the status is vague and may not correspond to the situation on the field.

The boundary description as per the notification is as follows:

North:- Starting from cairn No.1 at the trijunction of the boundaries of Coimbatore District, Marayoor Pakuthy and Kannan Devan Hills at the North West corner of the Reserve, the line goes in a nearly north easterly direction for about 5643/4 chains along the Chinnar River to cairn No.2 at a State Boundary Survey Stone on the bank of the Chinnar River, thence more or less east- south east for about 2141/4 chains along the above said river to cairn No.3 at the State Boundary Survey Stone on the bank of the river side of that Survey No. for about 11/4 chains to cairn No.4 at its south west corner.

Ecological Boundaries

On the North and East, it shares a 30 km common boundary with the Anamalai Tiger Reserve of Tamil Nadu. On the West, it is bordered by the Eravikulam National Park. On the southern side, it is bordered by the Reserve Forests of Marayoor Sandal Division, part of Kurinjimala Sanctuary, and also by Revenue Lands. The Park provides ecological connectivity between the Anamalai Tiger Reserve and Eravikulam National Park.

Internal Boundaries

The description of internal boundaries demarcating the private rights admitted within the reserve is specified in the reserve notification of 1942. The boundaries of the rights admitted for the PWD quarters at Chinnar and the enclosure at Ollavayal is vague and needs to be verified on field.

Earlier the Sanctuary area was divided into two Sections namely Chinnar and Karimutty and internal boundary for the sections were specified. Forest Station system was introduced in 12August 2005 and the entire sanctuary was brought under one forest station Karimutty. Hence these section boundaries became irrelevant.
