In commemoration of Earth Day 2026, OLU WATER, under RDL Corporate Responsibility, partnered with the NLDB Sri Lanka (National Livestock Development Board) to implement a targeted site rehabilitation initiative at an NLDB Manikpalama farmland opposite Haritha Kanda, Bopaththalawa. The actioned NLDB site is not a protected area but remains ecologically significant within the broader cloud forest landscape. Our prior assessments conducted in 2025 across the landscape indicated that approximately 67% of a 32Ha mapped area was under moderate to severe invasive species pressure. Also, the increased visitor activities during the Sinhala and Tamil New Year period further contributed to non-biodegradable waste accumulation at the site.
A rapid pre-intervention biodiversity assessment was conducted in the demarcated site to identify the presence of any threatened species requiring safeguards. As no such species were recorded within, the actions followed. The restorations preliminary phase therefore proceeded with a combined focus on non-biodegradable solid waste removal and invasive species management. Target species included Austroeupatorium inulifolium and Cymbopogon nardus. Removal was conducted using mechanized support, including a Harrow–Trailing and rotavator uprooting, (under the direct supervision of NLDB farm management) which followed by manual collection. Overall, the action occurred in the least infested invasive plant available land (4.89 Ha) as a pilot area to test restoration possibility.
A total of 26 participants, including NLDB personnel and Team Olu, contributed to the intervention. Uprooted biomass was systematically collected for composting, minimizing secondary ecological disturbance while facilitating nutrient recycling. The project will follow native grass introduction at the second phase. This activity functioned as a stepping stone in ecological response to address Biological Pollution (our theme to the 2026 financial year) within a broader restoration framework. This also enables community driven action in non-protected highland ecosystem.
