Sanjay Gandhi National Park (SGNP) officials are concerned because of the growth of an invasive species of Ipomoea Carnea, also colloquially known as Bush Morning Glory plant, on the banks of the Lake Vihar.

Experts say that the invasive weed will devour the lake, because of its rapid growth. Park authorities have decided to write a letter to the BMC for permission to remove this plant at the earliest, a report in this newspaper said.
