About 10 per cent of the Barrington Tops National Park was damaged in last summer's bushfires.
The area was among several ancient Gondwana rainforests on Australia's east coast to be affected by fire.
The NSW government has faced widespread community calls to significantly boost conservation efforts, with the bushfires devastating national parks and wildlife.
The international community has also raised concerns about NSW's ancient forests.
The Newcastle Herald reported recently that the conservation status of the Gondwana rainforests was changed in the World Heritage Outlook from "good with some concerns" in 2017 to "significant concern" in 2020.
These rainforests are the last remnants of the supercontinent Gondwana, which broke up about 180 million years ago. Usually they are too wet to burn.
About 4011 hectares of rainforest at Barrington Tops was affected by the fires.
The World Heritage Outlook, which was compiled by the official advisory body on nature to the UNESCO World Heritage Committee, said the most prevalent threats to such areas were "invasive alien species and climate change". Asked what was being done about this, a National Parks and Wildlife Service spokesperson said the weed control programs in the Barrington Tops "target invasive environmental weeds including scotch broom, lantana, ox-eye daisy and blackberry".
Recently, the wildlife service, Hunter Local Land Services and a group of volunteers removed scotch broom from a 3.5-hectare area of Barrington Tops. More volunteer events are planned before June.
The wildlife service added that it had completed "seven pest management operations across fire-impacted bush in Barrington Tops", including "ground-based baiting and trapping programs and aerial baiting and shooting programs".
It stated that about "80,000 baits" had been laid across national parks and reserves within the Hunter and Central Coast area in 2020.
"Shooting programs are estimated to have removed 1700 pest animals across the region, which is critical to protecting and supporting native flora and fauna recovery," the spokesperson said.
IN THE NEWS:
The wildlife service said it was focused on building "firefighting capacity and resilience ... in NSW".
The NSW government has funded 125 additional firefighters for the wildlife service, including "13 dedicated positions within the Hunter and Central Coast region".
Additionally, the National Parks and Wildlife Act has been amended to "provide for special measures for places of exceptional significance".
And a special ecological risk team will be established within the wildlife service to "inform the development of future fire strategies".
"A climate change adaptation plan is being developed for the Tweed Caldera group of reserves in the northern section of the Gondwana World Heritage Area," the spokesperson said.
"It is intended that this will inform further work to protect and conserve the world heritage area and rainforests across NSW and Queensland, including Barrington Tops National Park."
