The plan of the district administration to de-silt Canoly canal and the Kallayi river as part of a beautification drive is likely to have an adverse impact on large acres of wetland in and around Kottuli, according to a latest study conducted by a researcher from the Department of Architecture, National Institute of Technology-Calicut.

Kottuli wetland is one of the largest eco- patches within the city limits identified by the Ministry of Environment and Forests under National Wetland Conservation Programme.
