Immediate action on habitat loss is needed to secure the future of the Sumatran elephant, according to WWF.
A subspecies of the Asian elephant (Elephas maximus), the Sumatran elephant has been uplisted by the IUCN Red List from Endangered to Critically Endangered after losing nearly 70% of its habitat and half its population in the last 25 years.
This dramatic decline is largely due to widespread deforestation on the island of Sumatra, Indonesia, with much of the elephant’s natural habitat being converted for agriculture, oil palm production and timber plantations.
Rapid deforestation rate
Three subspecies of Asian elephant are generally recognised: the Sumatran elephant (Elephas maximus sumatranus) on Sumatra, the Sri Lankan elephant (E. m. maximus) in Sri Lanka, and the Indian elephant (E. m. indicus) on the Asian mainland.
Although Sumatra holds some of the most significant populations of Asian elephants outside of India and Sri Lanka, it has experienced some of the most rapid deforestation rates within the species’ range. As a result of increasing human encroachment, many elephant populations have come into conflict with humans, and Asian elephants are also illegally targeted for their ivory.
Only an estimated 2,400 to 2,800 Sumatran elephants now remain in the wild, and the species has been lost from many parts of the island. Confined to the remaining forest patches, many herds are now too small and isolated to remain viable in the long term.
If current trends continue, it is feared that the Sumatran elephant could become extinct within the next 30 years.
Urgent action needed
“The Sumatran elephant joins a growing list of Indonesian species that are Critically Endangered, including the Sumatran orangutan, the Javan and Sumatran rhinos and the Sumatran tiger,” said Dr Carlos Drews, Director of WWF’s Global Species Programme.
“Unless urgent and effective conservation action is taken these magnificent animals are likely to go extinct within our lifetime.”
WWF is calling on the Indonesian government to ban all forest conversion in elephant habitat until a conservation strategy can be put in place to conserve the species. It also recommends that large patches of habitat should be designated as protected areas, and that smaller areas should be linked with habitat corridors.
According to Asian elephant expert Ajay Desai, “It’s very important that the Government of Indonesia, conservation organisations and agro-forestry companies recognise the critical status of elephant and other wildlife in Sumatra and take effective steps to conserve them.”
“Indonesia must act now before it’s too late to protect Sumatra’s last remaining natural forests, especially elephant habitats.”
