From 2023, several CEPA activities were conducted in the Park; however, the Park was opened to general public on early 2025.

Overall aims of the centre

To conserve and enhance the Gothatuwa wetland as a flood retention area while transforming it into a sustainable, nature-based recreational, educational, and tourism destination.

Description of the centre

Location: 6°55'42.9"N 79°54'06.6"E
Public access via B231, Kolonnawa - Gothatuwa -Angoda road.
Gothatuwa Wetland Park is located in the Kolonnawa Divisional Secretariat Division, Colombo District of the Western Province of Sri Lanka.
This is located within the Kolonnawa Sanctuary, which is the largest natural wetland within Colombo Ramsar wetland city.
Size of site: 35-hectare
Types of habitats and species supported:
The Gothatuwa wetland mainly comprises different habitat types, including different vegetation types. Annona woodlands, Mixed woodlands, Herb-dominated High Vegetation, Water with Floating Vegetation, Open Water, and Highland Vegetation associated with wetlands are the prominent vegetation types. A total of 374 fauna species were recorded, comprising 221 vertebrates and 154 invertebrates. Among the vertebrates, there were 13 amphibians, 44 fish, 36 reptiles, 108 birds, and 20 mammals. The invertebrates included 78 butterflies, 29 dragonflies, 41 moths, and 5 snails. The 2025 biodiversity assessment recorded a total of 33 endemic fauna species within the Gothatuwa Wetland Park. Of these, six species were identified as nationally threatened with extinction, highlighting the conservation significance of the site.
A total of 248 flora species were recorded, including 243 flowering plants and 5 ferns. Among the flowering plants, 7 were endemic, 144 were native, 76 were introduced, and 16 were introduced as well as alien invasive species. Among the flowering plants, 7 endemics and 2 threatened species were recorded. All these were terrestrial plants. (Biodiversity survey, Jan 2025)
Featured programs:
i. Urban Wetland School Program: Hands-on environmental education activities for school children, including practical science activities (e.g., bird watching, soil and water testing), and interactive learning sessions aligned with national curricula, field learning programs i.e wetland art and photography.
ii. Wetland recreation activities including cycling and jogging, overnight camping experience at camping deck.
iii. Community Volunteer Initiatives: Regular wetland clean-up campaigns, tree planting events, habitat restoration programs with local communities, and CSR partners.
iv. Public CEPA Events: Awareness-raising events on World Wetlands Day and significant environment days featuring guided nature walks through Forest Walk and Marsh Walk, exhibitions, and wetland talks.

Work Areas

Main CEPA work area

Communication:
Maintain an active online presence through social media platforms including Facebook and Instagram, use printed media such as newspapers and leaflets to communicate wetland park features, wetland values and responsible visitor behavior.
Education:
Gothatuwa Wetland Park hosts hands-on environmental education activities for schoolchildren, including practical science activities (e.g., bird watching, soil and water testing), and interactive learning sessions
aligned with national curricula, field learning programs.
Participation:
Engage diverse stakeholder groups in wetland stewardship through community-led wetland clean-up and tree planting events, citizen science initiatives in water quality testing, volunteer programs involving Rotaract club, school groups, and CSR partners.
Awareness-Raising:
Public engagement is fostered through celebrations of environmental days with youth-focused programs and awareness sessions tailored to
different age groups.

Top three successes

  1. Protecting Gothatuwa Wetland from Public Encroachment. The Gothatuwa wetland, once an active paddy field, has faced significant encroachment due to rapid urbanization. Initial efforts like building a protective periphery canal helped somewhat but were insufficient to stop land invasion. To restore the lost connection between residents and the wetland, a barrier was constructed and transformed into a cycling track and walking path encouraging cycling and walking around the wetland. This initiative not only helps protect the wetland but also promotes healthy lifestyles and stress reduction in the densely populated area, addressing non-communicable diseases through recreational engagement with nature.
  2. Public Health Camp at Gothatuwa Wetland Park, themed “Healthy Wetlands, Healthy People,” This initiative connected wetland conservation with urban public health, highlighting how healthy wetlands contribute to community well-being. The camp promoted sustainable wetland management while showcasing Gothatuwa Wetland Park as a hub for recreation and environmental education. By framing wetlands as essential for both ecological and human health, the event attracted strong public participation and interest.
  3. World Wetland Day commemoration - 2025 A collaborative event bringing together experts, conservationists, youth, and community members to promote wetland preservation. Funded by the UNDP GEF/SGP OP7 Colombo Wetlands Programme and organized by the Sri Lanka Land Development Corporation with partner organizations, the program featured knowledge-sharing sessions and interactive activities, reinforcing collective responsibility for conserving wetlands for future generations.

Top three challenges

  1. Pollution from the catchment
    Inflow of wastewater, solid waste, and other pollutants from upstream drainage and nearby settlements, degrading water quality and biodiversity.
  2. Limited Resources for Management and Outreach
    Constraints in funding hinder regular maintenance and construction completion.
  3. Flooding
    Being a wetland, Gothatuwa Wetland Park is vulnerable to flooding due to intense rainfall, altered natural drainage paths, and irregular upstream water inflows. Flood events can damage infrastructure, disrupt visitor activities, affect surrounding communities, and impact wetland habitats and biodiversity. Addressing these challenges is critical to the park’s sustainability and its role as an urban nature-based solution.
