此外，婆羅洲之心（Heart of Borneo）也在受保護的範圍內，該區面積2,200萬公頃的婆羅洲雨林可說是紅毛猩猩、亞洲象，和蘇門答臘犀牛最後的棲地之一。
The Asia Development Bank today announced that it will provide a $1.5 million grant for environmentalists to work with Brunei, Indonesia, Malaysia and the Philippines to protect the region's seas and rainforests which the bank says "are being damaged at an alarming rate."
The region includes the Coral Triangle, which has the highest marine biodiversity in the world. Covering only two percent of the world's ocean, the Coral Triangle contains 76 percent of all known coral species and a wide variety of fish due to this high coral diversity. Over 120 million people directly depend on these seas for their food and income.
The region also takes in the Heart of Borneo, rainforests covering 22 million hectares that are some of the last refuges for orangutans, Asian elephants, and Sumatran rhinos.
Each year logging, mining and farming destroys millions of hectares of forests, including those supposedly legally protected, threatening the extinction of a wide range of species.
Overfishing and destructive fishing methods including the use of cyanide and dynamite have destroyed large coral areas and depleted marine resources. Global warming may hasten the damage, the bank said.
"The degradation threatens millions of people who rely on the natural resources for their livelihoods," said Urooj Malik, director of agriculture, environment and natural resources of the bank's Southeast Asia Department. "Urgent attention is needed to stop the deforestation and damage to the marine environment."
The grant will provide funding for the global conservation organization WWF to undertake an environmental and socio-economic profile of the region.
GIS mapping and stakeholder consultations in the four countries are intended to lead to the development of a long-term program to establish regional environmental management policies and strategies to strengthen the sustainable management of natural resources.
The grant also will allow the countries to assess policies and institutional capabilities in managing natural resources. They will address cross-border environmental issues such as trans-boundary haze pollution.
The four countries will determine requirements for strengthening institutional and coordination mechanisms, and implement policies through setting of minimum standards, monitoring and self regulation.
