With the Orroral Valley fire declared "out", ACT authorities have begun planning the slow recovery for the scorched Namadgi National Park.
The ACT government has published findings of an initial assessment of the damage caused by the blaze, which burnt through 80 per cent of Namadgi - and more than a third of the territory's land mass - after igniting on January 27.
The assessment highlights the scale and ferocity of the blaze, with a map showing swathes of severely fire-affected areas across the length and breadth of the 84,000-hectare fire ground.
It outlines the short-term priorities for the recovery in Namadgi and Tidbinbilla Nature Reserve, more than a fifth of which was also burnt in the fire.
The report identified 23 "risks" which require urgent attention, including threats to flora, fauna, cultural heritage, infrastructure assets and the possibility of flooding and erosion.
The dangers of feral cats and foxes preying on threatened animals has been identified as an "extreme risk", as was the damage to native plants caused by feral horses, deer and pigs.
Damage to aboriginal rock art and historic huts in the park have also been listed as an "extreme" risk.
The so-called "rapid risk assessment" published on Tuesday is the first stage in setting out a plan for the long-term recovery of the area.
The long-term program will look beyond the immediate recovery of fire and flood affected areas to examine "broader ecosystems trends and drivers", such as climate change and prolonged dry conditions, according to the report. It will also look at ways to safeguard Canberra's water supply.
The report said the recovery process would be guided by seven principles, headlined by the government's commitment to "walk together" with traditional custodians to "heal Country".
Mick Gentleman, who is the ACT's environment and emergency services minister, was last month tasked with overseeing the government's response to the Orroral Valley fire.
The government has also appointed ecologist Margaret Kitchin as the ACT's acting commissioner for sustainability and the environment, after Kate Auty stepped down from the position on Friday.
