Yayorin (Yayasan Orangutan Indonesia) is a non-governmental organization (NGO) whose main activities focus on research, education and conservation of orangutans and other wildlife, as well as the tropical rainforests as their habitats.

Yayorin was established in July 4th, 1991, at the city of Pangkalan Bun, Central Kalimantan (Indonesian Borneo) and believes in the vision of “the preservation of the forest for the welfare of human beings today and of next generations to come.”

Through its activities, Yayorin believes in the empowerment of the local communities who live in the surrounding forests and in the ability of these communities to manage their own forest and natural resources. In addition, Yayorin also tries to promote orangutan conservation through environmental education efforts, such as: visiting remote villages, local schools and governmental institutions, as well as developing educational programs that can bring real benefits to the local population.
