Ocean Lanka strengthens rainforest restoration efforts with successful Phase 02 of Cinnamon Rainforest Conservation Project
Reinforcing its commitment to environmental sustainability and biodiversity conservation, Ocean Lanka (Pvt) Ltd, Sri Lanka’s leading weft-knitted fabric manufacturer, has successfully completed Phase 02 of the Cinnamon Rainforest Conservation Project, a reforestation initiative bordering the globally renowned Sinharaja Rainforest.
Implemented under the Dilmah Conservation Restoration Project in Delwala, Ratnapura, the initiative brought together students of the Environmental Technology Society of the University of Colombo, Greenwood Growers, and other conservation partners to plant native tree species in the Waddagala area. Building on the success of Phase 01, the latest phase focused not only on expanding restoration efforts but also on monitoring the ecological recovery of previously replanted lands.
What began with fragile two-foot saplings has evolved into a thriving restoration programme, with many trees now reaching nearly four feet in height. These young native species are already contributing to soil stabilization, encouraging natural regeneration, and creating habitats for wildlife returning to the restored rainforest corridor.
The project has recorded remarkable success, with more than 85% of the saplings planted during the initial phase surviving despite challenging dry weather conditions experienced earlier this year. Native canopy species have shown strong growth, while birds and small mammals have gradually returned to the area. Volunteers and local communities have played a vital role in protecting saplings, removing invasive species, and supporting the ecosystem’s recovery.
To date, nearly 22,000 native trees have been planted under the broader restoration programme. Scientific biodiversity monitoring has also revealed significant ecological improvements within the restoration zone. Faunal diversity has increased from 189 to 251 species, including a notable rise in butterfly populations, while native flora diversity has expanded from 92 to 123 species.
The project’s progress continues to be guided through scientific monitoring methods such as permanent sampling plots, belt transects, and biodiversity tracking, ensuring measurable and long-term environmental impact.
Commenting on the initiative, Dr. Thakshila Nadeeshani Dharmapriya of the University of Colombo said, “These partnerships demonstrate the power of collaboration between the public and private sectors in conserving and restoring our natural heritage. The Dilmah Reforestation Project stands as a practical example of how science, partnership, and community engagement can revive degraded ecosystems. We are already witnessing a significant resurgence in biodiversity within the area.”
The continued success of the Cinnamon Rainforest Conservation Project highlights the importance of sustained conservation efforts and collaborative action in safeguarding Sri Lanka’s unique rainforest ecosystems for future generations.
