Fields and wetlands have been submerged for the final a number of days and it has prompted an irreparable loss to people and wildlife,” Lal mentioned.

Beneath Undertaking Crocodile initiated in 1975 by the Authorities of India, 47 gharials introduced from the Morena captive breeding centre in Madhya Pradesh have been launched into Punjab’s Beas River in three batches.
Gitanjali Kanwar, senior coordinator, aquatic biodiversity, World Wildlife Fund for Nature-India, who has been a part of the gharial conservation undertaking in Punjab, mentioned there are about 40 reptiles in Harike and the large flooding has raised critical considerations about their existence.
“Of the estimated gharial inhabitants sighted within the belt, 90% are juveniles, weak to being swept away within the large present. These reptiles have been launched in Beas however now they’ve made a habitat in Sutlej. There may be each risk that they have been swept away downstream into Pakistan,” she added.
