A rare frog that survived floods and drought in the Upper Murray is increasing in numbers.
The Booroolong frog is listed as threatened in Victoria and its numbers are declining in New South Wales.
But a survey has revealed its habitat has recovered and numbers are on the rise.
Glen Johnson, a senior biodiversity officer with the Department of Sustainability and the Environment, says the frog's habitat has been restored.
"The frogs have been able to rebound back into some areas which they had become locally extinct from," he said.
He says the breed has shown great resilience to have survived nine years of drought and unprecedented floods.
"They have come out the other end looking to be very positive for it," he said.
