Taronga Zoo is
celebrating breeding the Zoo’s first Southern Hairy-nosed Wombat in 30 years,
unlocking secrets which could also help their critically endangered wild
cousins. The female
joey, named Turra (meaning shadow or shade from the Aboriginal Kaurna
language group) recently emerged from mom Korra’s pouch and is a triumph for
the Zoo’s efforts on behalf of the species; until recently they were thought to
be completely extinct in New South Wales and have been notoriously difficult to
breed in captivity.
After many unfruitful matings since efforts began in 2002, a
few new factors were applied that led to success. “We decided this time to leave the male in with the females for the
whole year,” said Keeper Samantha Elton. “We took a hands-off approach and also
provided them with new soil to let them create their own burrows. Hoping our
male, Noojee, would breed this year, we added a healthy dose of competition by
placing another male in the den. Apparently wombats favor certain individuals,
so compatibility certainly played a role.”
Little is
known about the development of Wombat pouch young, however Korra is very
relaxed in her environment, often sleeping on her back, giving Taronga Keepers
the unique opportunity to monitor and measure the joey.
“This has
provided invaluable information. We were very lucky to have been able to check
on the joey from when it measured just 6 cm and was still hairless,” Samantha
added.
Southern
Hairy-nosed Wombat numbers in the wild are in decline with loss of habitat,
road deaths, drought, competition for food from introduced species, and, more
recently, the debilitating infestation of Sarcoptic Mange. Information gained from
zoo breeding programs is crucial in ensuring the survival of this species.
