The NSW Government has spotlighted the achievements of its rewilding projects – coinciding with today being commemorated across Australia as National Threatened Species Day.

10 locally extinct species were reintroduced to three feral-free areas in NSW national parks and regular monitoring has found that across the three feral predator-free sites, all species reintroduced into their native habitat are thriving and breeding successfully.

Australian Wildlife Conservancy Chief Executive Tim Allard said the feral free areas in NSW are helping reverse the trend of biodiversity decline and extinctions of our most vulnerable species.

“Effective partnership between Government and conservation organisations is helping deliver the resources and expertise required to provide conservation at scale and this is critical to restoring our country’s unique biodiversity,” Allard said.

NSW Minister for Environment James Griffin said within three years of animals being reintroduced to their native habitats, NSW is already turning back the tide on extinctions.

Minister Griffin advised “we set out a bold plan backed by science to create areas where we could eradicate feral predators and reintroduce locally extinct animals like the bilby and numbat, which have been extinct in the wild in NSW for more than 100 years.

“Feral cats and foxes are a huge threat to our native species and are a key driver of high extinction rates, with cats alone responsible for killing 1.5 billion native animals nationally every year.

“This is a world-leading program of rewilding, with a goal of returning the bush to how it was before feral animals were introduced 200 years ago.

“It’s incredible to see that in such a short period of time, we’re on track to remove at least 10 animals from the NSW extinct list – the first time this will have happened anywhere in the world.”

To help threatened species thrive into the future, the NSW Government is establishing seven feral-free rewilding sites in NSW.

Once they’re complete, 65,000 hectares of national parks will be free from feral predators, providing a significant conservation benefit for more than 50 species.

The three established sites so far are the Pilliga State Conservation Area, Mallee Cliffs National Park and Sturt National Park.

In partnership with NPWS, Australian Wildlife Conservancy (AWC) delivers the Mallee Cliffs and Pilliga rewilding programs, and University of NSW Wild Deserts delivers the Sturt National Park site program.

Regular monitoring has found that across the three feral predator-free sites, all species reintroduced into their native habitat are thriving and breeding successfully.

UNSW Wild Deserts lead Professor Richard Kingsford said it is great to see the whole ecosystem recovering and showing that removal of feral pests can make a real difference.

Professor Kingsford added “this is where we are really starting to see the results of not only the season but the benefits of good management and our collaborations, delivering conservation at scale. It really does make a difference to actively manage these landscapes and remove feral animals.”

QUICK FACTS

At the Pilliga State Conservation Area site:

• The reintroduced population of bridled nailtail wallaby has increased by 350%
• Yellow-footed antechinus abundance is 10 times higher inside the feral predator free area than outside
• There has been a five-fold increase in the bilby population since 60 founders were reintroduced in late 2018
• Occupancy and abundance of the threatened Pilliga mouse is higher inside the fence than outside

At Mallee Cliffs National Park:

• The bilby population has tripled from 50 to more than 170
• Small mammals, including the common dunnart, are more abundant inside the fence compared to outside
• A species of planigale has been recorded for the first time at the national park, inside the feral predator free area
• A markedly higher number of malleefowl breeding mounds are active inside the feral predator free area compared with outside

At Sturt National Park:

• The population of Shark Bay bandicoots has doubled from 13 to 26 only six months after they were released.
• The crest-tailed mulgara population has boomed from 19 to now more than 240
• Bilby numbers have increased from 10 to 60
• Recent surveys recorded nearly double the rate of small mammal captures inside the feral predator-free areas compared to outside, including Forrest’s mice, threatened dusky hopping mice and plains mice, which until recently were considered extinct
