The Black Summer bushfires devastated greater glider habitat across south-eastern Australia but researchers hope a new nesting box will help aid their recovery.

There are hopes that a modified nesting option will help boost the number of greater gliders in Gippsland as the forest begins to regenerate some 18 months on.

Australian National University research fellow Kara Youngentob said about one-third of the southern glider habitat was severely burned by the fires.

"It is possible that some areas of those forests will recover because eucalyptus has adapted to fire," Dr Youngentob said.

"But in some cases, it will be so extreme that the drought and heat wave and previous fires will keep them from coming back."
