In line with the United Nations Decade on Ecosystem Restoration, the "Regreen Hantana: Restoration of Degraded Lands" initiative is working towards revitalizing 4 hectares of degraded land within the Hantana Environmental Protected Area in Sri Lanka. The primary objective of this project is to rehabilitate deteriorated areas within the Hantana Mountain Range, aiming to enhance various ecosystem benefits such as biodiversity, carbon storage, watershed management, and soil preservation.

During the initial phase of this project more than 1000 seedlings of native tree species were carefully planted on a 1-hectare section of the degraded site in Hantana. This collaborative effort was spearheaded by the Faculty of Science and The Center for Environmental Sustainability (CES) at the University of Peradeniya, working in partnership with the Forest Department of Sri Lanka and the local community. Notably, 120 volunteers representing diverse groups including the university community, Forest Department, Central Environmental Authority, Ecological Association of Sri Lanka, and the local community actively participated in this significant endeavor.

During the project's second phase in 2023, the University of Peradeniya partnered with Commercial Bank, offering financial support and logistical assistance through ‘Thuru Piri Ratak’. A total of 1700 native seedlings, including Etamba (Mangifera zeylanica), Kahata (Careya arborea), Mee (Madhuca longifolia), Kumbuk (Terminalia arjuna), Domba (Calophyllum inophyllum), Karanda (Pongamia pinnata), Madan (Syzygium cumini), Wal Del (Artocarpus nobilis), Kudu Dawula (Neolitsea cassia), Kitul (Caryota urens), Kenda (Macaranga sp.) and Nuga (Ficus spp.), were planted across 1.5 hectares of degraded lands owned by the University of Peradeniya.
