SYDNEY, Feb 11 (NNN-XINHUA) – Ecologists have given some of Australia’s cutest and rarest native animals, red-tailed phascogales and numbats, new leases of life, by relocating them from one end of the island continent to the other.
The Australian Wildlife Conservancy (AWC) announced that, 60 phascogales have made the 1,400 km journey from Alice Springs Desert Park, in the Northern Territory to the Mallee Cliffs National Park, in the south-western region of the state of New South Wales (NSW).
Their new home within the 9,570-hectare parkland is protected by electrified fence to safeguard native animals from feral predators, such as cats and foxes.
The species is the fifth to be restored to Mallee Cliffs, since the fenced area was declared predator-free in Mar, 2020, as part of a partnership between AWC and the NSW National Parks and Wildlife Service (NPWS).
The ecologists hope the phascogale population will eventually grow to more than 1,500 when the tiny nocturnal animals settle.
“The return of the red-tailed phascogale to Mallee Cliffs, represents an important step in the long-term conservation of the species,” said NPWS ecologist, Dr Laurence Berry.
“By exposing individuals to different environmental conditions, we are helping to maintain the adaptive and evolutionary potential of the species, which may help to increase its resilience of ongoing climate change.”
About 20 of the phascogales have arrived, wearing collars fitted with transmitters, to monitor their movements, as they settle into their new environment. AWC chief science officer, Dr John Kanowski, said, data collected from the collars would be invaluable.
“Although the collars will only be on them for a few weeks, the data gathered will show us what vegetation they favour for shelter, where they go, and their rate of survival,” Kanowski said.
Among the phascogales’ new neighbours are 20 numbats, which have also travelled far this week. Five are from Perth Zoo in Western Australia, about 3,000 km away, and the other 15 are from AWC’s Scotia Wildlife Sanctuary in NSW.
The Perth numbats actually began their long journey in early Dec, during national COVID-19 travel restrictions, which led to the little marsupials spending more than a month in the South Australian capital of Adelaide.
AWC ecologists gathered up the numbats at Adelaide, where they then boarded a charter flight to NSW, followed by a two-hour drive to their new home.
Mallee Cliffs already has some resident numbats, which were released in the sanctuary in 2020.
AWC ecologists say, although it might be a few days or weeks before the new arrivals come across the already settled numbats, they are hopeful that “the marsupial mingling will run smoothly, and breeding will soon follow.”
The sudden arrival of the numbats is not so good news, however, for the parkland’s termites, as the small marsupials consume about 20,000 of the insects daily.
Ecologists estimate, there are less than 1,000 numbats remaining in Australia, making them rarer than the population of giant pandas.– NNN-XINHUA
