Crudia zeylanica brought back from extinction to mark National Tree Planting Day 

  • Organised by Wildlife and Nature Protection Society (WNPS) 

In celebration of National Tree Planting Day which fell on 15 November, a tree planting event was conducted on 14 November at the Bellanwila-Attidiya Sanctuary, the site of WNPS’s “Green Isle Project”. The initial idea and commitment came from Seyara and her friends from Visakha Vidyalaya to plant 100 trees of recommended species. A highlight of the event was the planting of five saplings of the endemic Crudia zeylanica, which was believed to be extinct in the wild. 

The Green Isle Project: Restoration of a critically important urban wetland sanctuary 

WNPS Green Isle Project Chairperson Dr. Nirmali De Silva, addressing the gathering, Himesh Dilruwan Jayasinghe, Central Environment Authority Chairman Siripala Amarasinghe, Visakha Vidyalaya student Seyara Vidanagamage, Department of Wildlife Conservation Director – Operations Ranjan Marasinghe, and WNPS President Spencer Manuelpillai 

Wildlife and Nature Protection Society (WNPS) launched The Green Isle Project in 2019, to restore a part of the degraded urban wetland of Bellanwila-Attidiya Sanctuary which was gazetted in 1990. According to records the Sanctuary is home to more than 150 species of birds including migratory and endemic, and more than 20 species of mammals. While being a habitat with incredible diversity, it provides critical environment services like flood control, air-purification, water-purification, minimising impacts from “urban heat island effect” and helping to make the urban fringes of Colombo cooler to name a few. 

The main objective of the Green Isle Project is the Habitat Restoration for Species Conservation in the Bellanwila-Attidiya sanctuary, to provide a refuge to the primate species Purple-faced leaf monkey or Nestor commonly called “kalu wandura” in Sinhala, which is an endangered endemic species that is fast losing its habitat in the urban and suburban areas of the Western Province.

Through well-planned scientific restoration activities, WNPS has enriched this space with over 1,500 scientifically identified plants and this marked a historical tree planting exercise, where for the first time in a tree planting programme, five saplings of Crudia zeylanica were planted at the site – a species that has been very much in the news in the recent times. WNPS was happy to be joined by Himesh Jayasinghe at this occasion, who in 2019 rediscovered this tree, after it was declared extinct. 

Wetlands play a critical role in environmental and coastal protection and natural urban wetlands are extremely rare. Sadly, there are grave threats to Wetlands in Sri Lanka including habitat loss and exploitation, spread of invasive plant species and encroachment by humans for “development” amongst other reasons. WNPS is grateful for the continued effort by the Department of Wildlife Conservation (DWC) who are fighting many legal battles to protect this area. 

Urgent appeal to provide protection for Bellanwila-Attidiya Sanctuary under the Ramsar Convention 

The Colombo metropolitan city has been identified as one of the first Ramsar wetland cities, comprising the following wetlands: 

  • Beddagana wetland 
  • Diyasauru wetland
  • Heen ela wetland
  • Kolonnawa wetland
  • Kotte wetland
  • Maddinnagoda wetland
  • Mulleriyawa wetland
  • Thalangama wetland 

WNPS would like to appeal to the authorities to annex the Bellanwila-Attidiya Sanctuary to the Ramsar list, as this will provide this important wetland habitat a much-needed, higher level of protection.

WNPS wishes to commend the students from Visakha Vidyala, for their participation at this occasion and sincerely hope that this event will be an inspiration to more of Sri Lanka’s youth to become environmentally conscious and to choose to protect the rich biodiversity of our motherland.

A collaborative effort

WNPS wishes to thank Sri Lanka Land Development Corporation (SLLDC) who provided a heavy-duty amphibian dredger to clear the thick vegetation at the initial stages of the Green Isle Project. The project was steered by Prof. Lakdas Fernando, who is passionate about restoring the habitat that existed many years ago and WNPS is grateful for his environmental leadership.  

The project would not have been possible without our financial partners of the project – Abans PLC and LG. Their partnership with the Green Isle Project at the Bellanwila-Attidiya Sanctuary represents Abans’ and LG’s latest efforts to promote sustainable living in Sri Lanka as a part of their “LG Loves Green Sri Lanka” campaign. This CSR initiative aims to contribute towards the cause of preservation of Sri Lankan wildlife by transforming the suburban wetland region into a “green lung”.
