Planting of saplings, screening of films on climate change, green walk, art exhibition and painting and slogan writing competitions marked World Environment Day celebrations here on Saturday.

As part of environment protection, the Army officials have realigned a few areas inside the Palm Grove Environment Park and Training Area on Island Grounds, resulting in the formation of small ponds, said Lt. Gen. B.K. Chengappa, General Officer Commanding, Andhra, Tamil Nadu, Karnataka and Kerala. Normally, during rain, the grounds get waterlogged. With the creation of new ponds, water stagnation could be avoided.

In the last four years, nearly 2,000 saplings were planted and provided adequate protection. Use of plastic has been banned on the grounds as well residential quarters of defence personnel. In the next few years the grounds would become a lush green lung as officials planned to plant more saplings, said Lt. Gen. Chengappa.

He distributed prizes to winners of painting and slogan writing competitions. K.S. Neelakantan, Additional Principal Chief Conservator of Forests (Administration) planted a sapling on the grounds.
