WWF’s mission is to stop the degradation of the planet’s natural environ- ment and to build a future in which humans live in harmony with nature, by: conserving the world’s biological diversity, ensuring that the use of renewable natural resources is sustainable, and promoting the reduction of pollution and wasteful consumption. THE ENVIRONMENTAL STATUS OF THE HEART OF BORNEO V Introduction The island of Borneo, encompassing parts of HoB is also known for the cultural and linguistic Indonesia, Malaysia, and Brunei, is recognized diversity of the several ethnic groups of as a global conservation priority, yet over the indigenous peoples collectively known as Dayak. last few decades the lowland portions of the Local people depend on the forest for a variety island of Borneo in Indonesia has suffered of resources including: food, medicinal plants, from deforestation, forest fire, and conversion non-timber forest products for trade, wild game, to estate crops. The central upland portions of fish, construction materials and water. The the island are more remote and generally less traditional management practices of the Dayak suitable for industrial exploitation – these areas communities have contributed to sustainable are relatively intact. management of natural resources of the area over the last centuries. The urgent need to address the lowland conservation issues notwithstanding; initiatives The ultimate measure of the success or failure to take advantage of the opportunity represented of conservation initiatives will be the ecological in the intactness of central areas have gained health and sustainability of institutions which traction in the last ten years. In February support that ecological health. Therefore the 2007, the governments of Brunei Darussalam, development of a monitoring framework Indonesia and Malaysia signed the Heart of which could characterize both the ecological Borneo (HoB) Declaration which commits the health and conservation status of the HoB was three governments to a single conservation initiated in 2007.The objectives then were: (1) vision to ensure the effective management of Develop a set of practical indicators that might forest resources and conservation of a network be representative of the ecological status of the of protected areas, productive forests and other HoB and could be monitored at appropriate sustainable land uses in the upland HoB.
