On a request made by the Department of Wildlife Conservation, Sri Lanka Navy Hydrographic Service (SLNHS) is undertaking a survey of a degraded mangrove ecosystem in Anawilundawa Sanctuary in Arachchikattuwa Divisional Secretariat. The Wildlife Conservation Department expects to restore the mangrove in the above ecosystem, which was destroyed by former shrimp farming. This site has been abandoned since 1991 and efforts are being taken to rehabilitate these wetland areas to its former glory of the Bio Diversity eco-system.
A team consists with Director Hydrographic Operations, Captain (H) EMA Bandara, Professor Sevvandi Jayakodi, Senior Lecturer on Environmental Sciences in the Wayamba University and Officials of the Department of Wildlife Conservation have visited the area on 12th February 2022 for the conduct of preliminary studies. Based on these actions will be taken to restore acidize soil, improve water circulation and replant the Sanctuary to its former glory. Sri Lanka Navy has been pioneering the growing of mangroves in coastal area in this Island Nation and that experience also will be utilized in this effort.
