Borneo ablaze: forest fires threaten world’s largest remaining population of orangutans Kara Moses, special to mongabay.com August 16, 2009
‘These fires have started as a result of human actions.’ says Dr. Suwido Limin, Director of the Indonesian peatland conservation organization CIMTROP. ‘Newcomers to the area have attempted to follow traditional Dayak farming methods for land clearance but they lack the experience to control the fires they start. When peat dries out it burns very easily and at great temperatures. Once these fires take hold, they burn and burn and can be almost impossible to put out until the rains come again. In that time huge areas of forest and irreplaceable peat deposits may be lost.’ Peat fires can smolder for years below the surface.
The area currently at risk, the peat-swamp forests of Sabangau National Park and surrounding areas, houses an estimated 8,000 orangutans as well as eight other primate species, clouded leopards, sun bears, flying squirrels and 154 species of bird. The Sabangau forest is the largest area of lowland rainforest remaining in Borneo. ‘Orangutan sleeping nests can be seen in trees shrouded in smoke and rhinoceros hornbills fly through the haze overhead.’ was the scene described in a press release issued by OuTrop (Orangutan Tropical Peatland Project). OuTrop is an independent research and conservation project carrying out research into the biodiversity of the Sabangau Forest, with a focus on the area’s orangutans.
A dedicated rapid-response fire-fighting team, known locally as TSA (Tim Serbu Api), is currently working around the clock to tackle the fires. The team of 30 local people is trained and equipped by CIMTROP. Their job is extremely hazardous, as Dr. Limin explains; ‘Peat fires are unique as they spread below the surface, on average 20-30cm below ground but sometimes as deep as 60cm, which makes fighting them both dangerous and unpredictable. You can put out fire in one place and then flames suddenly shoot up behind you.’ The team are constructing fire breaks and suppressing the fires with water pumped from nearby canals and bore-holes. These holes can take three or four people up to six hours to dig, as they often need to be over twenty meters deep to access enough water. Just one square meter of burning peat can take two to three hundred liters of water to be extinguished.
Major fires occur in the area every three to four years but are not easily predictable. ‘We need to … have funds permanently available for immediate use when fire hits.’ says Dr Limin. ‘Disasters do not wait while mitigation strategies are discussed and put in place; they hit hard and fast, with little warning. We rely on donations, and are very grateful for the financial support we receive, but at the moment we simply don’t have the resources we need to tackle all the fires that are starting.” Peat forms when organic matter remains only partially decomposed due to heavily waterlogged, acidic conditions. The deposits at Sabangau are up to fifteen meters deep and took 20,000 years to form. They can store huge amounts of carbon but this is released into the atmosphere as CO2 when they are burnt. Indonesia houses over 20 million hectares of peatlands, acting as a store for billions of tons of carbon.
