Orang-utan extinction threat shortens
نویسنده
چکیده
The orang-utan could be virtually extinct within five years after it was discovered that the animal’s rainforest habitat is being destroyed even more rapidly than had been predicted five years ago. A United Nations Environment Programme (UNEP) report has found that illegal logging and fires have been overtaken as the primary cause of deforestation by a huge expansion in oil palm plantations, which are being created to meet soaring demand from Western food manufacturers and the growing zeal for biofuels. The UNEP report ‘The last stand of the orang-utan: state of emergency’ says natural rainforests of Indonesia and Malaysia are being cleared so rapidly that up to 98 per cent may be destroyed by 2022, and the lowland forest stronghold of orang-utans much sooner, unless urgent action is taken. This is a decade earlier than the previous report estimated when it was published five years ago. Overall the loss of orang-utan habitats is happening 30 per cent more rapidly than had previously been thought. Satellite images reveal that illegal logging is now taking place in 27 of 41 national parks in Indonesia and is probably still on the increase. The report says: ‘At current rates of intrusions, it is likely that some parks may become severely degraded in as little as three to five years, that is by 2012.’ The report says: ‘Today, the rapid increase in [oil palm] plantation acreage is one of the greatest threats to orangutans and the forests on which they depend. In Malaysia and Indonesia, it is now the primary cause of permanent rainforest loss. The huge demand for this versatile product makes it very Worries about the survival of the orang-utan are deepening, according to a new UN report, writes Nigel Williams.

The orang-utan Pongo spp. is protected by national and international legislation, yet populations continue to decline. Many reports implicate local people in the poaching and illegal trade in orang-utans, yet community participation has been promoted as an alternative conservation strategy. To explore how community-based orang-utan conservation could be developed, we conducted a study to unders...

A survey of the density and population size of Bornean orang-utan (Pongo pygmaeus) was carried out in 1995 and 1996 in an area of peat swamp forest in the Sungai (River) Sebangau catchment, Central Kalimantan, Indonesia. Densities were calculated for four forest sub-types by counts of orang-utan sleeping platforms (nests) along line transects. Densities were found to be highest in the tall inte...

BACKGROUND Today the majority of wild great ape populations are found outside of the network of protected areas in both Africa and Asia, therefore determining if these populations are able to survive in forests that are exploited for timber or other extractive uses and how this is managed, is paramount for their conservation. METHODOLOGY/PRINCIPAL FINDINGS In 2007, the "Kinabatangan Orang-uta...

The geographic distribution of Bornean orang-utans and its overlap with existing land-use categories (protected areas, logging and plantation concessions) is a necessary foundation to prioritize conservation planning. Based on an extensive orang-utan survey dataset and a number of environmental variables, we modelled an orang-utan distribution map. The modelled orang-utan distribution map cover...
