Mancherial: Notwithstanding the pollution at Ram Cheruvu, spectacular species of butterflies continue to thrive on the bund of the lake located in the heart of Mancherial district headquarters. Though the discharge of sewage generated from nearby colonies into the lake makes it stink, the pleasant chirpings of the rich avian community and the winged creatures continue to surround the water body.
As the sun sets, drunkards and youngsters dump empty bottles of liquor and cold drinks into the tank following the lack of dustbins and security guards near the lake. The release of sewage into the water body is also a cause of concern among morning walkers and environmentalists.
Surprisingly, the unlawful acts have failed to dampen the spirits of butterflies dwelling on the bund and the polluted environs have become a safe haven to a host of these species. The bund is home to common tiger butterfly, also known as striped tiger butterfly, mottled emigrant, common crow, common mime, common baronet, swallowtail, common grass yellow and small white butterfly. While common crow is vulnerable, common mime is presently endangered.
“Despite the pollution, several species of butterflies, including some vulnerable, have been found to be inhabiting the bund of Ram Cheruvu since several decades, which enhance the look of the water body. They also enthrall the visitors at the tank,” Gundeti Yogeshwar, a State master trainer at National Green Corps told Telangana Today. However, walkers say the officials concerned must take steps to protect the butterflies that play a vital role in maintaining the ecology. “Authorities of the municipality must take steps to keep the tank and premises of the lake clean. The presence of biodiversity has been affected in many ways due to the pollution of the tank,” Mallaiah, Ram Cheruvu Walkers Association president, rued.
“Butterflies are indicators of a healthy environment and a healthy ecosystems. They are an important element of the food chain. They are a hearty meal for birds, bats, and other insectivorous animals. Like bees, these wonderful species play a vital role in pollination, the process of reproduction and pest control,” Venugopal Satla, a deputy forest range officer of Jankapur in Kumram Bheem district said.
