Other mammals found in the sanctuary are Leopards, Jungle Cats, Leopard cats, Spotted deer, Sambardeer, Gaur, Sloth bear, Wild dog, Wild boar, Indian pangolin, Stripe-necked mongoose etc. Due to ecological and geographical contiguity with other protected areas of Bandipur and Nagarhole Tiger Reserve in North-East side and Mudumalai Tiger Reserve of Tamilnadu in the south-eastern side, offers natural corridors for the seasonal migration of ling ranging animals within the greater conservation unit. It is the only sanctuary in Kerala where sightings of four-horned antelope (Ullaman) are reported. The most remarkable thing about the sanctuary is that it is the only remaining habitat of the critically endangered vulture population in Kerala. Two species of vultures, viz., Red-headed and white-backed vultures are a common sight in the sanctuary.


Values of Wayanad Wildlife Sanctuary

Biological

The sanctuary is part of one of the most important tiger habitat in the country. This forest continuum, as part of Project Elephant Reserve No. 7, harbours the largest and viable population of Asian elephants in the world. Constitute western limits of vast dry and moist deciduous forest continuum, spread over three states of Karnataka, Tamilnadu and Kerala and act as corridors for seasonal migration of wild animals.

Conceptual

As an inevitable component of NBR, the forests of this area are believed to be home to numerous, still undocumented, floral and faunal species. The last legally well protected remnants of the badly fragmented and encroached forests of Wayanad plateau.

Ecological processes and functions

Sanctuary's forests form major catchments of various tributaries of Cauvery river system, one of the largest river systems in South India.

Scientific

The Nagarhole-Bandipur-Mudumalai-Wayanad - complex is site of numerous ongoing research activities by prominent South Indian research organizations.

Educational & Recreational

The easy terrain and location at tri-junction of 3 states, offers tremendous scope for spreading the message of conservation through nature education & eco-tourism package. The very common sights of major animals, especially wild elephants, and the salubrious climate of sanctuary, make sanctuary areas excellent eco-tourism spots.

Historical

Discovery of new stone-age relics in sanctuary open up new possibilities for anthropological studies and for building up the natural history of this area.

Economic

The vast teak plantations of sanctuary harbour billions of rupees of timber assets. Even though fellings in these plantations are stopped, conversion of these plantations in to natural forests necessitates selective removal of teak trees which will yield crores of rupees revenue and give considerable employment to local population. Wayanad being a predominantly tribals dominated area, sanctuary’s forestry activities play a vital role in generating employment and tackling poverty related problems of local population. There is scope and immediate need for a full-fledged eco-development effort to reduce human degradations on forests as well to improve plight of the stakeholders.


Indigenous People

Wayanad hosts among the highest population of indigenous civilians in the State. Some of the prominent tribes here include the Paniyar, Kattunayakan, Urali, Kurichiar, Wayanad Kadar and Adyar. Said to be of Dravidian ancestry, they depend almost completely on the forest for their livelihood. Honey, spices, medicinal plants, roots and gooseberry are some of the non-timber products that they rely on the forest for. The main non-tribal community here is the Wayanadan Chetty. The Kerala Forest Department has launched various initiatives to foster the growth and empower these indigenous settlers.
