Phase 2: 11th of November 2023

Celebrating the milestone of the "Regreen Hantana: Restoration of Degraded Lands in Hantana Environmental Protection Area (HEPA)", a seedling transplantation event took place on the 11th of November 2023, at the restoration site near the Animal Science farm of the Faculty of Agriculture, UoP at Uda-Peradeniya with the participation of over 350 volunteers. This initiative is spearheaded by the Faculty of Science and the Centre for Environment Sustainability, University of Peradeniya in partnership with the Commercial Bank, Forest Department, and the Local Community.

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.

An awareness session was conducted at the outset of the event to emphasize the significance of 'Restoring the degraded lands for enhancement of ecosystem services', 'Role of next generation in conserving forest resources' and 'Multistakeholder partnership for restoration projects' by Prof. M.D. Lamawansha (Vice-chancellor, UoP), Mr. Saneth Jayasundara (Senior Regional Manager (Central), Prof. R.G.S.C. Rajapakse (Dean, Faculty of Science, UoP), Prof. Tilak Hewawasam (Director, Centre for Environmental Sustainability), Mr. Sumudu Gunawardena (Chief Information Officer, Commercial Bank), Mr. U.G.R. Pushpakumara (Former Grama Niladhari, Palle Peradeniya Division) and Prof. Thilanka Gunaratne (Team Leader, Regreen Hanatana Project).

Regreen Hantana: Restoration of Degraded Lands

Current global challenges confronting humanity include consequences of climate change, such as the escalation of temperatures and sea levels, unpredictable weather patterns, increase in severe weather events, degradation of land, and decline in biodiversity. As a response, there is a rapid evolution of ideas related to sustainable development and environmental preservation, aimed at adapting and mitigating the impacts of climate change.

The forest cover of the Hantana Environmental Protection Area (HEPA) contributes to many ecosystem services including conservation of aquifers, carbon sequestration, regulation of local climate, soil protection, biodiversity conservation, and preservation of aesthetic value of the landscape. The Regreen Hantana Project was proposed by Prof. M.D. Lamawanasa (Vice-chancellor, University of Peradeniya) in 2022, aiming to restore degraded lands, thereby improving ecosystem services provided by the HEPA as an investment for the future of the planet earth. The initial phase of the project involved in transplanting seedlings of three native tree species (Kahata/Careya arborea, Mee /Madhuca longifolia, and Nika/Vitex negundo) along with one endemic tree species (Atamba /Mangifera zeylanica) in a degraded site near the Agriculture Farm at Mawalawatta, Uda Peradeniya, on the 18th of December, 2022.

Later, on the 6th of August 2023, a Shramadhana campaign took place at the site to clear the weedy regrowth near the transplanted seedlings. This event was organized by the Student Conservation Leaders of the Regreen Hantana Project, under the guidance of Prof. Thilanka Gunaratne (Team Leader) and Mr. Saumya Bandara (Student Coordinator). Sixty-six volunteers representing the university community and villagers living around the restoration site participated in the event to clean weeds around the transplants, install covers to prevent herbivory and transport native tree seedlings from the site to the Department of Botany, UoP.

Prof. Tilak Hewawasam (Director/Center for Environmental Sustainability), Prof. Rupika Rajakaruna, Dr. Nadeesha Koralegedara, Dr. Chaminda Wijesundara and Dr. Priyanga Wijesinghe also participated in this event. Moreover, Grama Seva Niladari, Mr. H.M. Navarathne Bandara (present) and Mr. U.G.R. Pushpakumara (former Grama Seva Niladhari) along with 20 villagers participated in site maintenance activities.

The Regreen Hantana community intends pursue their social and environmental endeavors aimed at rejuvenating the forests within the Hantana Environmental Protection Area, ensuring its conservation for generations to come.
