Tamil Nadu notifies three new elephant corridors
Tamil Nadu's Environment, Climate Change and Forests Department has formally notified three elephant corridors within the Hosur Forest Division
The corridors are Jawalagiri-Panai-Anchetty, Jawalagiri-Ulibanda-Thaggatti, and Billikkal-Jawalagiri, together covering more than 10,300 hectares of reserve forest and wildlife sanctuary land
The corridors will facilitate the seasonal, trans-Cauvery migration of elephants and other large mammals between Tamil Nadu and Karnataka
As all three corridors lie within existing reserve forests or protected sanctuary areas, the notification does not change the legal land classification, but grants the corridors formal conservation recognition
Elephant Corridors and the Wildlife (Protection) Act, 1972
An elephant corridor is a land linkage that connects two or more elephant habitats, allowing elephants to move between fragmented forest patches for feeding, breeding, and seasonal migration without being blocked by human settlements, plantations, or infrastructure. Corridors are not a separate protected-area category under the Wildlife (Protection) Act, 1972 (unlike National Parks or Wildlife Sanctuaries); instead, corridor notification is typically an executive/administrative recognition (often reinforced by state forest department orders or court directions) layered on top of existing reserve forest or sanctuary status.
Key Details
- The Wildlife (Protection) Act, 1972 protects the Asian elephant (Elephas maximus) under Schedule I, the highest protection category, prohibiting hunting and trade
- India has 33 declared Elephant Reserves and around 150 identified elephant corridors nationwide (Wildlife Institute of India assessments)
- Project Elephant, launched in February 1992 by the (then) Ministry of Environment and Forests, is the Centrally Sponsored Scheme that funds elephant habitat protection, corridor management, and anti-poaching efforts
- India holds over 60% of the global wild Asian elephant population, making corridor connectivity nationally significant for the species' long-term survival
The Hosur corridors' notification is a state-level conservation designation that formalizes long-used elephant migration routes, giving them recognized status for planning purposes even though their underlying legal land classification (reserve forest/sanctuary) remains unchanged.
Sigur Elephant Corridor Case — Supreme Court on Corridors vs Private Property Rights
The Sigur Plateau elephant corridor case in the neighbouring Nilgiris district is the landmark precedent on the legal weight of elephant corridor notifications. The Supreme Court, in October 2020, upheld a Madras High Court order affirming Tamil Nadu's authority to notify an elephant corridor in the Sigur Plateau, and directed eviction of resorts and private structures obstructing the corridor. The Court reaffirmed this position in a December 2024 order, referring residual land-classification and compensation disputes back for committee examination.
Key Details
- Supreme Court (14 October 2020): upheld Tamil Nadu's power to notify the Sigur elephant corridor and ordered eviction of resorts/structures blocking elephant movement
- December 2024 order: reaffirmed the 2020 verdict; allowed a court-appointed committee/Madras High Court to examine specific land-demarcation and compensation objections
- The Court has held that the ecological necessity of unobstructed elephant movement can override private commercial land use within a notified corridor
- Forest Rights Act, 2006 claims of Scheduled Tribes and traditional forest dwellers within such corridors are handled separately and have not been foreclosed by these corridor rulings
The Hosur corridors follow the same conservation logic upheld in the Sigur case — recognizing habitat connectivity as a priority — though here the corridors already lie within reserve forest/sanctuary land, avoiding the private-property eviction disputes seen at Sigur.
Cauvery North Wildlife Sanctuary and Trans-Boundary Habitat Connectivity
The Hosur Forest Division corridors lie within and adjoining the Cauvery North Wildlife Sanctuary, part of a larger landscape (including the Cauvery South Wildlife Sanctuary and Karnataka's forest divisions) that supports elephant movement across the Tamil Nadu-Karnataka border, driven by seasonal water and fodder availability.
Key Details
- Wildlife Sanctuaries (under the Wildlife (Protection) Act, 1972) permit limited regulated human activity, unlike National Parks, which prohibit it; both differ from Tiger Reserves, which have a legally mandated core-buffer structure under Section 38V
- Elephant movement across the Tamil Nadu-Karnataka border is largely driven by monsoon patterns and seasonal changes in water/fodder availability, making unbroken habitat linkage between the two states ecologically essential
- Human-elephant conflict mitigation is a stated objective of formal corridor recognition, since blocked traditional routes increase encounters with human settlements
Notifying the three Hosur corridors extends formal habitat-connectivity protection along the Tamil Nadu-Karnataka elephant landscape, complementing the Cauvery North and South Wildlife Sanctuaries in maintaining a continuous trans-Cauvery corridor network.
- Three corridors notified: Jawalagiri-Panai-Anchetty (largest, 20.90 km, 6,881.47 hectares), Jawalagiri-Ulibanda-Thaggatti (18.50 km, 3,241.53 hectares), Billikkal-Jawalagiri (smallest, 2.20 km, about 196 hectares)
- Combined area: more than 10,300 hectares of reserve forest/wildlife sanctuary land
- Notifying authority: Environment, Climate Change and Forests Department, Government of Tamil Nadu
- Asian elephant: Schedule I species under Wildlife (Protection) Act, 1972; listed as Endangered on the IUCN Red List
- Project Elephant launched: February 1992
- India's elephant reserves: 33 declared reserves; approximately 150 identified corridors nationwide
- India's share of global wild Asian elephant population: over 60%
