With death looming large on the highly endangered tiger species effective conservation measure are the only solutions. But these measures do not come easily in case of a lack luster approach as has been seen on many instances.
The World Wide Fund or WWF has tested two drones that will locate poachers and inform the authorities. The unarmed drones are capable of patrolling 25 sq km at a time. These are set to monitor conservation units in Nepal and tests have already been conducted in Chitwan National Park.
The tiger reserves in India are very susceptible to poaching. This has been noted in the past at Panna and recently at Tadoba Tiger Reserve in Maharashtra. An innovative and proactive approach is required and the drones set a fine example.
