In the year 2001, we proposed to make the Anawilundawa Sanctuary, a Ramsa Wetland. The RAMSA declaration aims to safeguard wetland ecosystems in a variety of ways. The only Ramsar wetland in Sri Lanka was Bundala Wetland till 1991. Other than that, no other wetland was included on the Ramsar list.
It was initial days of my duties at the Wildlife Conservation Department. Mr. Dharmakeerthi oversaw the Development and Management Division, where I was employed as an Assistant Director at the time. During that time, Mr. D.P. Gunasekara served as the Director General of Wildlife, and Mr. ChandralalHerath held the position of the Deputy Director.
They all agreed that Anavilundawa is an important sanctuary and the lakes and ecosystemsin it should be protected. But the data related to Anavilundawa was minimal and finding related data was a heavy task. I could only find the 1:50,000 map and 1:10,000 map of the Survey Department. My superiors asked me to get support from the International Union for Conservation of Nature (IUCN) for this project.
As I recently joined the service and was unaware that departmental vehicles could be utilized for official purposes. At that time, the Department of Wildlife Conservation was located at Gregory Road, Colombo. The IUCN office was near Thimbrigasaya. I rolled up the maps and came to IUCN by bus. It was headed by Dr. ChannaBambaradeniya, while Mr. Sandun Perera and some other officers were there. There, we decided to go on a field trip to Anawilunda. Accordingly, we went on a field visit in a Wildlife Department vehicle and an IUCN vehicle. In this field visit, we met Arachchikattua Divisional Secretary, Mr. Alex Fernando. He was very happy after hearing the details and promised to give maximum support.
We went on several field visits. Initially, the people around did not like this task and they thought that it was something underhanded. People also did a protest campaign against us. As IUCN was mentioned, it must have been thought that it was an internationalized deal. We made a map and booklet of the area.
We did not have an office in Anawilunda. Anavilundawa was managed from the regional office on the Colombo Puttalam road, while the Assistant Director’s office was in Anuradhapura. The Divisional Secretary said that we will have a meeting with the people of the area. In this area, there were fishermen, farmers, people who come from remote areas for sand mining, and people who are involved in the tourism industry. The meeting was attended by the Divisional Secretary, IUCN representatives, Wildlife Conservation Department officials, Fishermen’s Associations, Agricultural socities etc. People had a good understanding of the value of ecosystems in Anavilundawa Sanctuary. After the meeting, people knew that this was going to be good work. Over time, people became friendly with us.
The Divisional Secretary gave land to build the Beat office. People liked it because it was difficult to do illegal activities when there was a beat office. We did three main analyses, namely social, biodiversity and land use. Social analysis was conducted by IUCN through a questionnaire. Information about the opinions of the people of the village regarding conservation, their wishes about the need of the project was obtained.
We used information from Dr. Samararatne of the Central Environment Authority in addition to what we already knew about biodiversity. In terms of land use, data related to how houses are located, the location of mangroves, lakes, and water levels were obtained. Finally, the prepared report was forwarded to the Ramsar office at the IUCN headquarters in Gland, Switzerland. This work took about a year. Finally, on 1st of August, 2001, we were able to declare AnawilundaRamsa Wetland. It is the second Ramsar wetland in Sri Lanka.
I’m satisfied with the work I did on this. I recently paid a visit to the lady who we called “Nenda” lived at the house where we used to park our cars and spend our brief stays together. She is now staying somewhere else. However, tears welled up in her eyes at seeing me. She talked about the advantages that this area has seen since Ramsar Wetlands were declared. I feel proud of myself for this Anavilundava endeavor in my professional life.

The Anawilundawa Wetland which was declared a sanctuary under the Fauna and Flora Protection Ordinance by the Department of Wildlife Conservation on 11 June 1997, was designated as a Ramsar Wetland of International Importance (especially for migratory water birds) on 03 August 2001. This was due to the richness of biodiversity, acting as a feeding ground for migratory birds and historical and cultural value.
The boundary of the sanctuary is BattuluOya – Udappapuwa highway in the north, Puttalam – Halawatha railway line in the east, SengalOya in the south and Paru Canal (Holland Canal) in the west. Its size is about 1397 hectares.
It consists of an ancient system of tanks arranged in the Ellanga irrigation system by King Parakramabahu around the 12th century B C. It consists of 07 shallow main tanks known as Anavilundawa, Pinkattatiya, Suruvila, Maiyava, Maradan Sole, Vellawala and Irakkawila or upper lake.
Anavilundawa Sanctuary is a unique ecosystem in Sri Lanka, with its coastal belt surrounded by the sea, mangrove communities and a freshwater irrigation system. Providing habitat for tens of thousands of local and foreign birds, this sanctuary is a perfect haven for aquatic fauna as well as aquatic floral community.
About 131 species of indigenous birds and 37 species of endemic birds have been recorded in this sanctuary, which is a beautiful bird paradise. This unique ecological arrangement has made Anawilunda a favorable nesting and breeding ground for hundreds of bird species. It is a large breeding colony consisting of birds like Great cormorant (Phalacrocorax carbo), Asian open bill stork(Anastomus oscitans)etc., 20 mammal species, 11 amphibian species, 34 reptile species, 74 butterfly species and 47 fish species have been recorded.Many endemic and resident birds can be observed throughout the year and migrants are best seen between October and April. Anavilundawa Bird Sanctuary is a very popular destination among bird watchers and nature lovers. They come here to see rare birds and to do nature photography.
Some of the observable birds
1960s, was a bad decade for the wetlands of the world led to the development of many wetlands in the world. Many wetlands were converted into agricultural lands. Some became settlements or cities. Due to this, many countries faced environmental changes. Due to many environmental changes such as floods, landslides, rising ambient temperature, people had to experience many hardships. Because of this, there was a need to draw the attention of the world communityregarding the adverse effects of reclamation of wetlands. As a result, 136 countries gathered in Ramsar, Iraq in 1971 and reached a convention for the conservation of wetlands in the world. That is the Ramsar Convention on Wetland Conservation. Realizing the importance of this convention, Sri Lanka also became a party to the Ramsar Convention on 15 October 1990. As a result, 6 wetland ecosystems in Sri Lanka have now been declared as International Ramsar Wetlands.
1) Bundala NP – 1990.06.15
2) Madu Ganga Reserve – 2001.08.03
3) Anavilundawa Reserve – 2003.12.11
4) Wankalei sanctuary – 2010.07.12
5) Kumana NP – 2010.10.29
6) Wilpattu NP – 2013.01.28
Due to its exceptional ecological value, Anawilundawa Sanctuary was declared an International Ramsar Wetland on 03 August 2001. There are many abandoned shrimp farms in this sanctuary of 1397 hectares belonging to Arachchikattuwa Divisional Secretariat area of Puttalam District. The Department of Wildlife Conservation took steps to replace the mangrove plants in the abandoned shrimp farms. Accordingly, the internal drainage pattern of the 4 hectares of abandoned land around the ferry canal was regularized and the suitable environment was re-created to replace the mangroves.
Also, 264 species of plants have been identified in the Anavilundawa sanctuary. Among these, 110 are trees, 54 are grasses, 68 are plants, 30 are vines and 2 are plants. Today, fishermen use the ferry canals for catching fish, and the mangrove plant community on both sides of the canals acts as a protective cover. Among the plants here, 13 species of mangrove-related plants such as Red mangrove (Rhizphora mucronata), Grey mangrove (Avicennia marina), Indian Mangrove (Avicennia officinalis), Blind-your-eye mangrove (Excoecaria agallocha), White-flowered black mangrove (Luminitzera recemosa), Cannonball mangrove (Xylocarpus granatum), Upriver orange mangrove (Bruguiera sexangula), East indian mangrove (CeriopsSps), Yamstick mangrove (Scyphiphora hydrophyllacea), Glass tree mangrove ( Heritierrali) and Mangrove palm (Nypa fruticans) can be seen here. The restoration of mangrove species, Upriver orange mangrove (Bruguiera sexangula), Flowering mangrove (Bruguiera cylindrica) & Black mangrove (Aegiceras corniculatum) which are adopted to the environment of Anawilundawa Sanctuary were re planted by the present day fisherman.
Good environmental management along with restoration of mangroves according to the scientific method, will increase the ecological, scientific, economic, social and educational value of Anavilundawa Sanctuary in the near future.The replacement of mangroves, which is being carried out with the support of the Ministry of Wildlife and Forestry and the technical consultancy of the North-West University, will also be carried out in the remaining areas where the shrimp farms used to be. It is expected to get the participation of non-governmental organizations and the business community for this task. Conserving the wetland environment, including the mangrove ecosystem, which is quietly being performed for the sustainable existence of all living beings on earth, is a great mission that we are doing today for a prosperous tomorrow.
Anawilundawa Sanctuary was declared as the 1078th Ramsar Wetland under the Ramsar Convention in August 2001. Although the area around the Anavilundawa Sanctuary was used for large-scale shrimp cultivation in the eighties, shrimp farms in that area was abandoned due to a widespread disease in the late nineties. Today, the Department of Wildlife Conservation has started a mangrove restoration project using that section of the land as a part of the land belonging to the Anavilunda sanctuary.
The brackish water wetland ecosystem of Anawilundawa Sanctuary is a haven for the proliferation of mangroves.Prevention of coastal erosion, wind control, soil conservation, acting as a breeding ground for aquatic organisms and fish species such as shrimps and crabs, producing and retaining nutrients, maintaining the existing interrelationship and ecological balance with the mangrove plant community and sea grass and coral reef ecosystemsare some of the services provided by mangroves which are very helpful for the survival of living communities including humans.
The Anavilundawa mangrove project has been supported by universities and private institutions, and currently about 40 hectares of natural mangroves suitable for the area have been successfully planted and 95% successof that amountis a favorable situation. Also, many projects such as removal of invasive plants within the wetlands are being implemented in protected areas including Bundala National Park.Thus, with the launching of such projects, these wetlands, which are likelungs of the island will be reactivated and provide life to living being including humans, and it will be possible to build a better environment for the future existence of human being.
