It's estimated 185 of Victoria's species, many of them rare and threatened, have already been impacted by this season's blazes.

The money will go towards food drops, treatment, rehabilitating habitats, ensuring protection from predators and research into affected species.

"A number of species have been endangered ... their habitat has been directly impacted by these fires," Premier Daniel Andrews said on Thursday.

"People are genuinely grieving to see so many of our native species injured, so many under real threat and they're very keen to see governments and all of our partners do more."

Victoria is the second state to airdrop food into inaccessible, bushfire-ravaged regions in an effort to save starving wildlife.

A reconnaissance flight on Tuesday determined the immediate priorities and locations for the drops, while food is being made available to teams on the ground in Buchan and Mallacoota in the state's east.

Zoos Victoria veterinary staff are staffing three wildlife triage centres and providing special pellets for kangaroos and wallabies, as well as their critically endangered cousin, the brush-tailed rock wallaby.

More than one billion animals are thought to have perished in the unprecedented bushfires across Australia, but the final extent won't be known for some time.

Data published on Monday by the federal Department of the Environment and Energy showed 49 species had seen more than 80 per cent of their known or likely habitat damaged in the fires.

For a further 65 species, at least half of their habitat was affected.

The threatened species include hundreds of plants, 16 mammals, 14 frogs, nine birds, seven reptiles, four insects, four fish and one spider species.

The federal government has pledged an initial $50 million wildlife and habitat restoration package.

Victorian Environment Minister Lily D'Ambrosio called for the federal money to start flowing.
