Borneo" region. Environmental group WWF was particularly active in the establishment of the protected area. In the "Heart of Borneo" project, non-governmental organizations (NGOs) have played a role in promoting the critical initiative and in assisting the transboundary nations in its conceptualization, design, and implementation. The transboundary nations are to improve biodiversity conservation in Bornean production forests, and to ensure that such forests are not simply converted to agricultural land-uses such as oil-palm plantations after logging.
