Wildlife authorities in Tamil Nadu have introduced a new mobile application for this year's synchronised Nilgiri Tahr survey, marking a technological leap in conservation efforts. State forest secretary Supriya Sahu announced that, for the first time, the department has deployed a dedicated mobile app called 'Varudai' for real-time data collection, GPS-based tracking, and standardised reporting. The app is supported by a web-based platform that enables near real-time integration of field data.
Enhanced Accuracy and Efficiency
The 'Varudai' app significantly improves accuracy and efficiency in analysing data collected across the Nilgiri Biosphere Reserve. It involves forest staff, volunteers, and researchers in a coordinated effort. This is the third survey of its kind, which began on Friday and concluded on Sunday.
Previous Survey Results
The first survey in 2024 estimated the Nilgiri Tahr population at 1,031 individuals. That number increased to 1,303 in last year's second survey, reflecting a 26 per cent rise and signalling successful conservation initiatives.
Extensive Coverage
The current survey spans 14 forest divisions, 43 ranges, 124 beats, and 177 survey blocks, covering over 3,100 kilometres—nearly double the distance recorded in the inaugural 2024 survey. It extends across the species' full range in Tamil Nadu, from Ashambu Mottai at 902 metres above sea level in Kanyakumari district in the south to Tavalamalai at 986 metres in Gudalur in the north.
