James Cook University (JCU) researchers are calling for urgent government support to protect the spectacled flying-fox from extinction as new and escalating threats push the species closer to the brink.
Despite their reputation as noisy and messy neighbours, spectacled flying-foxes play a vital role in the survival of Australia’s rainforests, travelling vast distances to pollinate flowers and spread seeds at levels unmatched by any other species.
JCU adjunct associate professor Noel Preece said recent research shows long-term threats such as land clearing and human persecution are now being compounded by climate change and invasive ants, leaving the species increasingly vulnerable.
“The spectacled flying fox is a keystone species,” Prof Preece said.
“It’s one of the great travellers in distributing seeds across the wet tropics and Cape York landscapes, and a major pollinator of the forest.
“They can fly over 100km from their roost to find food and return home, flying over 200 kilometres in a single night. They move fruit around, pollinate trees and prevent tree inbreeding, and they have evolved with the rainforest, so they play a vital role in the Wet Tropics.
“It will be truly catastrophic to our rainforests if they are gone.”
CSIRO monitoring has already highlighted a dramatic decline, with numbers dropping 75 per cent between 2004 and 2017. Preece said the lack of consistent government support for monitoring and conservation programs is alarming.
“There’s no indication that the population decline has turned around. There’s nothing to suggest that, and no reason we can think of that it would just turn around,” he said.
“We do need to get the government to support this as a long-term program.”
While flying-foxes have long struggled with public perception, Preece said many issues can be easily managed.
“The problems they cause can be managed, and their ecological value far outweighs the nuisance.”
