Overview
Wayanad Wildlife Sanctuary is a protected area located in the Wayanad district of the southern Indian state of Kerala. Established in 1973, the sanctuary encompasses a portion of the Western Ghats and forms part of the Nilgiri Biosphere Reserve, a UNESCO-designated biosphere reserve.
Geography and Climate
- Area: Approximately 344 km² (84,900 acres).
- Topography: The sanctuary lies on the eastern slopes of the Western Ghats and includes a mix of hills, valleys, and riverine systems, predominantly the Kabini and Kalindi rivers. Elevations range from about 600 m to 1,500 m above sea level.
- Climate: The region experiences a tropical monsoon climate with mean annual rainfall of 2,500–3,000 mm and average temperatures ranging from 15 °C in winter to 30 °C in summer.
Flora
The sanctuary falls within the South Western Ghats montane rain forest and moist deciduous forest ecoregions. Prominent vegetation types include:
- Evergreen and semi‑evergreen forests
- Moist deciduous and mixed deciduous forests
- Sholas (stunted tropical montane forest patches) at higher elevations
Characteristic tree species are Shorea spp., Mesua ferrea, Mimusops elengi, and Syzygium spp. Endemic and threatened plant taxa such as Lagarostrobus franklinii and several orchid species have been recorded.
Fauna
The sanctuary supports a diverse assemblage of wildlife, representative of the Nilgiri‑tamil madras plateau fauna:
- Mammals: Indian elephant (Elephas maximus), Bengal tiger (Panthera tigris tigris), Indian leopard (Panthera pardus fusca), gaur (Bos gaurus), sloth bear (Melursus ursinus), sambar (Rusa unicolor), chital (Axis axis), and Nilgiri langur (Semnopithecus johnii).
- Carnivores: Dhole (Cuon alpinus), jungle cat (Felis chaus), and fishing cat (Prionailurus viverrinus).
- Herbivores: Indian bison (gaur) and several species of deer and antelope.
- Birds: Over 200 species have been documented, including the great Indian hornbill (Buceros bicornis), Malabar pied hornbill (Anthracoceros coronatus), Malabar whistling thrush (Myophonus horsfieldii), and several endemic babblers.
- Reptiles and Amphibians: Indian rock python (Python molurus), monitor lizards, and a variety of caecilians and frogs typical of the Western Ghats.
Conservation Significance
As part of the Nilgiri Biosphere Reserve, the sanctuary contributes to landscape-level connectivity for wide-ranging species such as tigers and elephants. It also serves as a critical habitat for several threatened and endemic taxa. Conservation initiatives focus on habitat restoration, anti-poaching patrols, and community-based eco‑development programs.
Administration and Management
The sanctuary is administered by the Kerala Forest Department under the Wildlife Protection Act, 1972. Management activities include:
- Regular scientific monitoring of wildlife populations
- Fire prevention and control measures
- Regulation of tourism and issuance of permits for research and ecotourism activities
- Community outreach and involvement of local tribal groups in conservation projects
Tourism and Accessibility
- Access Points: Main entry is near the towns of Kalpetta and Sultan Bathery, with the nearest railway station at Kozhikode (Calicut) and the nearest airport at Calicut International Airport.
- Facilities: Designated safari zones, a visitor center, and guided trekking routes are available. Visitor numbers are regulated to minimize ecological disturbance.
Threats
Key pressures on the sanctuary include:
- Encroachment and illegal land‑use change for agriculture and settlement
- Human–wildlife conflict, particularly crop depredation by elephants and livestock predation by large carnivores
- Invasive plant species such as Lantana camara affecting native understory vegetation
Research and Monitoring
Numerous academic and governmental studies have been conducted within the sanctuary, focusing on wildlife ecology, landscape genetics, and the impacts of climate change on montane ecosystems. Data from camera traps, radio‑telemetry, and ecological surveys inform adaptive management strategies.
