We have been involved in the reforestation of degraded land through tree nursery and replanting projects in Sumatra since 2005, and have planted over 350,000 seedlings to date. Our latest project involves the regeneration of cleared forest in the Besitang region of the Gunung Leuser National Park. This programme is the first of its kind in Sumatra. We work in close collaboration with national park authorities and local people to undo damage caused through illegal conversion of protected land into plantation agriculture, with the initial target being the replanting of 500 hectares of orangutan habitat lost to development. We have facilitated the establishment of a group of farmers in Besitang who are committed to supporting the rehabilitation of GLNP and actively participate in the protection of the national park from further encroachment. In addition to forest rehabilitation, the project provides sustainable alternative livelihood schemes for local people living adjacent to the park. They benefit from the restoration of natural ecological services (having previously suffered droughts as a result of high water uptake from the illegal planting of oil palms), and also receive agroforestry and business development training. There is a strong educational element to the project, with training and skills development on tree nursery management and replanting seedlings, as well as the economic and environmental advantages of various tree species. Indigenous tree species planted include Sungkai (Peronema canescens), Pulai (Alstonia scholaris), Durian (Durio sp.), Jengkol (Archidendron pauciflorum) and Cempedak (Artocarpus champedan). Approximately 68,000 seedlings have now been planted on 68 hectares of degraded land. With the agroforestry training and establishment of tree nurseries well under way, we are now seeking funding to remove the remaining 100 hectares of illegal oil palm trees still growing within the protected area. We have been authorised to do this by the national park government authority, and then we will embark upon restoring this land with indigenous rainforest tree seedlings.
