In short:
Wildlife experts say the mass deaths of flying foxes along the east coast of NSW could have a domino effect on ecosystems.
uncertain
deaths → say → ecosystems
Grey-headed flying foxes have been found deceased or malnourished following a suspected lack of nectar.
asserted
foxes → fly → nectar
A health physician has warned people not to touch the bats as they could carry the deadly Lyssavirus.
uncertain
they → warn → Lyssavirus
A suspected flying fox mass starvation event along the east coast of Australia could disrupt the health of forest ecosystems, experts warn.
uncertain
experts → suspect → ecosystems
Wildlife carers between the New South Wales Mid North Coast and Victoria have been inundated with reports of malnourished, deceased or dying grey-headed flying foxes over the last few months.
asserted
carers → inundate → months
The bat species is suspected to have been impacted by a lack of nectar on flowering trees due to drought conditions, forcing them to seek out food closer to the ground.
asserted
species → suspect → ground
University of Newcastle conservation professor Matt Hayward said less nectar would have a ripple effect on other species too.
asserted
nectar → say → species
"Lots of Australian birds rely on nectar [as well as] flying foxes … so we could see a really big decline in all of those species," Mr Hayward said.
uncertain
Hayward → rely → species
As keystone pollinators, he said the flying foxes played a vital role in maintaining forest ecosystems, with species relying on the bat's nightly seed dispersal.
asserted
species → say → dispersal
Flying up to 50 kilometres each night, the bats disperseseeds they have eaten from trees, generating forest ecosystems.
asserted
they → fly → ecosystems
"So they're dispersing those seeds over really broad areas in the appropriate habitat for other species," Mr Hayward said.
asserted
Hayward → disperse → species
"Given that the climate is changing so rapidly we really need to ensure that genes [for plants] are being transferred over those distances.
asserted
genes → give → distances
"Plants are really going to need that kind of ability, to move and disperse, that flying foxes provide for them."
asserted
foxes → go → them
Mr Hayward said with the bats under even more stress, the species could be pushed further to the brink.
uncertain
species → say → brink
"Flying foxes [were already] vulnerable before this drought," he said.
asserted
he → say → drought
"And so now any pressure being put on them with habitat clearing or droughts is just going to put more pressure on the species and push them closer to extinction."
asserted
pressure → put → extinction
Hunter Wildlife said it has received an unprecedented number of calls this week for dead or dying flying foxes.
asserted
it → say → foxes
Volunteer Kerry Walker said it needed to be treated as an emergency.
asserted
it → say → emergency
"I mean this is a crisis, it's a disaster situation in reality so it should be responded to as a disaster,"she said.
"If we don't have [the bats] then we don't have the gum trees, then we don't have a whole lot of different species of birds or animals … it becomes a domino effect.
"
asserted
it → mean → birds
This is just another huge pressure on those [forest] species and the threatened species status will just collapse down the chain.
asserted
status → threaten → chain
"
Lyssavirus concerns
NSW Health said in the last two weeks, from September 28 to October 10, 43 people were assessed after being bitten by bats, and it had issued an alert for Lyssavirus risks.
asserted
it → say → risks
The fatal disease, part of the rabies virus group, is transmitted through bat saliva, through bites or scratches, and can cause swelling of the brain.
asserted
disease → transmit → brain
Hunter New England Health physician David Durheim said humans typically wanted to help animals when they were injured but it was important to understand the risks.
asserted
it → say → risks
"We hate to see animals struggling and particularly those lovely flying foxes with their very big eyes," Dr Durheim said.
asserted
Durheim → hate → eyes
"So if [bats] are affected by disease or starvation, currently a major issue, and we see them ailing, our first instinct is to help them.
asserted
instinct → affect → them
"[But] the key is to call a trained wildlife carer … they've been vaccinated and also know how to safely manage the right equipment for an animal that is struggling."
asserted
that → call → animal
