Interactive corridor impact map
Where the tigers go when they leave Nagzira
Dispersal from Navegaon-Nagzira runs north to the Kanha-Pench complex and south to Umred-Karhandla. These routes, not the reserve boundaries, decide whether the population stays connected.
Northern dispersal
Tigers moving north out of Navegaon-Nagzira link the Maharashtra population to the Kanha-Pench complex in Madhya Pradesh. This is the corridor most exposed to linear infrastructure and land-use change.
Southern dispersal
The southern route carries dispersing sub-adults toward Umred-Karhandla. Anti-poaching patrols and cattle-kill monitoring concentrate here during the dry season.
Conflict interface
Villages ringing the Navegaon-Nagzira Tiger Reserve are where conflict is decided. SEWA works as the link between residents and the forest administration, running Primary Response Teams and rapid rescue.
Why corridors, not just reserves
A reserve holds a population; a corridor keeps it from becoming an island. SEWA's dispersal study began in 2011 to give the Forest Department evidence it could act on, and camera trapping, patrolling, cattle-kill monitoring and forest-fire watch have run along these routes ever since.

Southern tropical dry deciduous forest
Teak-dominated dry deciduous forest over undulating ground, broken by grassland patches and by the Malguzari tank system — historical irrigation waterbodies that now carry much of the landscape's wetland biodiversity. Switch the map to Satellite to see the forest blocks, the tanks and the farmland between them.

- Continuous canopy inside the protected cores, fragmenting toward the corridor edges.
- Malguzari tanks
- Village waterbodies visible as dark patches; Sarus Crane breeding habitat.

Per-reserve tiger numbers are held by the Maharashtra Forest Department and the NTCA and are not reproduced here. SEWA publishes the figures it collects itself.
A corridor, used
69.2 km, one tigress, sixty days
Born to the tigress Alpha in New Nagzira, around October-November 2012, in a litter of three. Named for an abnormally small right eye.
In late 2014 she left New Nagzira Wildlife Sanctuary and walked to Navegaon Wildlife Sanctuary. SEWA tracked her the whole way and reported each movement as it happened to RFO Goregaon, RO and RFO Jambhdi, and the Deputy Director of NNTR, as the movement unfolded. The Forest Department confirmed her identity at the far end against its own records.

Had she not settled, the corridors open to her next were Rajnandgaon, Chhattisgarh — east; Gadchiroli — south; Brahmapuri-Tadoba — west. That is the argument for corridors in one animal: what she could reach depended entirely on what was still connected.
