Sumatran Orangutan Population Over Doubles Previous Estimates but Not for Long

Despite the fact that the Sumatran population has doubled in size, the international research team says this is unlikely to be the case for very long. With the pace at which their habitat is being cleared for agriculture, forest fires and the level of poaching, the population of Sumatran is likely to decline. The Sumatran (Pongo albii), and Bornean (Pongo pigmaeus) are the two main species of orangutans. They can be found in northern Sumatra’s forests. After conducting an extensive study, the Sumatran Orangutan population (also known as orangutang or orangutang or orangutang or either orang-utang or orangutang) has nearly 8 000 more people than previously estimated. Orangutans, which are fruit-eating frugivores, play an important role in dispersing seeds across large areas. Many tree species would be affected if they disappeared, particularly those that have larger seeds. Image: A higher number doesn’t necessarily mean that there are more primate species. The team emphasizes that this is due to the fact that the most recent survey was wider, which i.e. It covered more of the areas in which this animal has been documented to be living. If the habitat of this tree-eating great ape is degraded as it stands, then up to four ,500 people could die. 2030. Serge Wich from Liverpool John Moores University and his colleagues called for the Sumatran provincial and national authorities to adopt legislation that would protect forest habitats where orangutans are found. It is essential to have an accurate estimation of the population size of any species of animal or plant in order to plan conservation efforts. Therefore, to cover the Sumatran orangutan’s complete range, researchers from Indonesia and Europe carried out surveys during which over 3,000 nests on more than 200 line transects covering approximately 300 kilometres were counted, which equalled about 14,000 individuals. Named after the Malay word for “person of the forest”, the species is named. Sumatran orangutans, also known as Sumatran orangutans, are in grave danger. The World Wildlife Fund states that the Sumatran orangutan lives almost entirely in trees, and is a tree-dwelling species. The majority of females don’t travel to the ground, and males rarely do. (Image: A prior study estimated that there were only 6 ,600 people living in Northern Sumatra. The study did not include orangs who live at higher altitudes in forests and west of Lake Toga. Future deforestation is a grave threat to orangutans. Primatologists used computer simulations to simulate a variety of scenarios for deforestation. Their simulations showed that up to four ,500 anangutans might disappear by 2030, if the plans are implemented. Even though this is great news, the future of orangutans will likely decline rapidly unless there’s something done to stop it. Professor Wich from the University’s Faculty of Science spoke about the excitement of his and his coworkers at higher estimates, while also warning of the future of the orangutans. Many forest fires are being set intentionally to make way for new plantations. These slow-moving apes were believed to have died from the heat, and many more are still missing. Image: “We must continue working together with Indonesian officials and other stakeholders to prevent this from happening.” It is a difficult task but we hope we can change the course for Sumatran orangutans.” In a few years, there will likely be no wild orangutans. Hjalmar Kuehl (Photo:, project leader, works at Max Planck Institute for Evolutionary Anthropology (iDiv) and German Centre for Integrative Biodiversity Research. He said: “The Sumatran Orangutans will be the first ape species whose estimates of their population have been changed significantly by taking a closer look. We are likely to see corrections for many of the other ape taxes in the coming years. These will allow us to make better conservation and management decisions and guide the protection of great primates. Arif, Rudi H. Putra, Rio Ardi, Gabriella Fredriksson, Graham Usher, David L. A.

This BBC documentary examines the threats to this endangered species. This documentary also features the filming of the birth of a captive Orangutan.
