A project to create a bridge for orangutans in Borneo, alongside Japanese zoos

Activity grant

Project Description

Orangutans often cross rivers in the forests where they live, but in Borneo island, deforestation has occurred due to palm oil plantations. This means habitats are being divided, forcing groups of the animal to be isolated. This organization, along with local NGOs, used scrap hosepipes to build two trial bridges. These activities are being carried out with the Borneo Elephant Sanctuary and local NGOs, with Japanese zoo's taking part in the planning, and the bridges are designed with low environmental impact with participation from local villages. Specifically, the areas where bridge building is proposed are to be investigated, the materials and construction methods for the bridge is to be considered, training for the skills needed is to be provided at workshops, and three bridges will be hung on the Kinabatangan River downstream basin. By building a bridge to connect the divided habits, the orangutan's gene diversity is preserved, and a villager-led cross-linking system will be constructed. Furthermore, through involvement with the zoo's in Japan, the project is being returned to its origins by domestic environmental education.
