Devil Ark's bumper crop at Barrington Tops | photos, video

DEVIL Ark has added 51 newborns to their collection of the endangered marsupials in a positive sign for the species’ future.

The four-month-old joeys received their first health check on Thursday, the survivors from litters initially made up of more than 30. 

Despite reaching four months, the creatures will remain in the pouch until later in the year before venturing onto their mothers back.

They are expected to join the breeding population around December. 

Devil Ark president Tim Faulkner said the joeys were in perfect condition. “We couldn’t be more proud of how far we have come in the last 6 years,” he said on Thursday.

Devil Ark bills itself as the most successful captive breeding facility for the Tasmanian devil on the Australian mainland.

The Barrington Tops breeding base started with 44 animals in 2011 and now cares for a population of 154. 

Mainland breeding programs offer an insurance policy against the Devil Facial Tumour Disease. which has ravaged the wild population in their home state.
