NEW DELHI, september 17, 2023
Wildlife officials at one of the most populous tiger zones in India are experimenting with a new set of camera traps — or cameras with infrared sensors deployed in forests to count wild animals or monitor the movement of potential poachers — that harness the power of Artificial Intelligence (AI).
In experiments under way at the Kanha-Pench corridor in Madhya Pradesh, the system has, for the first time, caught poachers on camera that — a year down — helped forest authorities secure a conviction, according to a person involved in the experiment.
Cameras set up in remote regions are a key tool in surveys and census counts of tigers and elephants but have limitations such as requiring personnel physically access the machine to prise photos. They are also bulky and are not always optimised to conserve charge to keep the instruments running.
The new kind of camera set-up, called the TrailGuard AI camera-alert system, being tested are slim devices that can be inconspicuously set up within the foliage of trees.
Shaped like a pen, 13.8 cm long and 1.4 cm wide, it is wired to another ‘communications’ unit, the size of a notepad.
The system has embedded software that can be instructed to take pictures of specific species of interest. In the usual camera set-ups, the motion-triggered devices will snap pictures of anything — from a falling leaf to a jungle fowl that comes in its line of sight. The TrailGuard system can be set to specifically capture humans or species of interest — lions, tigers, cheetahs.
A team of researchers and developers involved in developing and testing the system, in an article published in the journal Biosciences report that 12 TrailGuard AI camera-alert systems were tested from mid-May to mid-July 2022 on the Kanha–Pench corridor along with seven camera-alert systems in the Dudhwa Tiger Reserve in early September 2022 to mid-December.
“Researchers and forest department officials received notifications of tiger presence via email or push notification between 30 and 42 seconds after detections. These notifications included tiger detections from three units that were within 300 meters of a village and from which there were also daily notifications of villagers grazing cattle or collecting forest products,” they note.
