Palm Oil pushing Gurney’s Pitta towards extinction

Gurney’s Pitta (Endangered) has declined by a staggering 70% in just 13 years, its rapid population plummet a result of habitat loss. Following its relatively recent extinction from Thailand, the species now occupies a small range of flat, low-lying forests in Myanmar. Unfortunately, these same forests are being cleared to make way for oil palm and betel nut plantations.

This isn’t the first time this striking species has been in danger of extinction. Widespread in Thailand before 1915, Gurney’s Pitta was feared extinct after there were no confirmed sightings between 1952 and 1985. Rediscovery came with excitement in 1986, and populations were then discovered in five separate locations. However, by 1997 the species had again dwindled – occurring in only one of its previous five Thai habitats. By this time, the global population was estimated at a mere nine pairs and the pitta was believed to be one of the rarest species on earth.

Luckily, a search for the species in Myanmar in 2003 found the bird at several sites and estimated the population at between 5,000 and 8,500 pairs. Despite this encouraging discovery, since then the decline has been precipitous. Whilst it is currently listed as Endangered, civil unrest within the final stronghold of the range could increase rates of habitat loss and push the species to Critically Endangered. Without slowing this decline through habitat protection, Gurney’s Pitta may disappear from Myanmar just as it has from Thailand, except this time there will be no second chance.

Tropical birds benefit from more forest by rivers in oil palm areas

Summary:

Protected riverbank habitats within areas of oil palm cultivation can play a key role in reducing the negative impacts on tropical bird numbers but need to be increased in size, new research from the University of Kent has shown.

Converting rainforests to oil palm plantations has well documented impacts on tropical wildlife, including birds. But so far there has been little research on the value natural vegetation in river areas in plantations has for nature, although these are often preserved for water management as 'riparian reserves'.

However, a new study, led by the Durrell Institute of Conservation and Ecology in the School of Anthropology and Conservation at the University of Kent, in partnership with Universiti Malaysia Sabah, demonstrates that riparian areas can help to lessen the negative impacts of oil palm cultivation on bird communities.

The team counted birds across 28 rivers at a site in Malaysia and were able to examine their findings in relation to the width of the protected forest alongside the rivers. The study showed that large riparian reserves tend to support more bird species, with the largest ones hosting similar number as nearby forests.
