President of NARG, Bill Waterhouse, is dedicated to the rescue and rehabilitation of injured native wildlife.

The most common animal injuries NARG treats are the result of a motor vehicle crash or accidental poisoning from pest control baits.

Mr Waterhouse said that the end of day light saving wreaked havoc on roads as wildlife and traffic were in transit at the same time.

"The cars are on the road when the wombats and kangaroos come out," Mr Waterhouse said.

"From the first day to when day light saving commences again, there will be an increase in motor vehicle accidents with wildlife."

Within 12 hours of day light saving ending on April 7, NARG took in two orphaned baby wombats whose mothers had been hit in traffic.

NARG aims to release rehabilitated animals back into the wild on properties that adjoin national parks, but often animals sustain injuries that prevent them from surviving in the wild.

Mr Waterhouse offered advice for drivers.

"Slow down, especially when you approach dusk and dawn," Mr Waterhouse said.

"If you hit an animal, put your safety first, get the car off the road, put on your hazard lights, and then safely get the animal off the road. If the animal is alive, give NARG a call."

For NARG, a good day is a quiet day, when no native wildlife has been injured or killed.

"Last year was horrific," Mr Waterhouse said. "People were counting the carcasses between Braidwood and Bungendore. There were well over 200 dead animals at one stage."
