A conservation enclosure for an endangered nocturnal species of wallaby, the mala, has been rebuilt at Kings Canyon in central Australia.

A wildfire swept through the area in January, burning the fence, feeding stations and vegetation, and killing six of the animals.

More than 40 survived.

Rangers have been providing food and water because of a lack of vegetation in the 170 hectare enclosure.

Acting regional chief ranger Gary Weir says Parks and Wildlife rangers have put in temporary shelters to protect the mala from predators and have rebuilt the fence.

"We have had a pretty good outcome, even though it was very sad to loose half a dozen animals," he said.

"The mala now are able to go about their normal day to day activities."

The mala are small animals weighing up to 1.6 kilograms.

They were virtually wiped out after European settlement by fire and feral predators, including cats and foxes.

The animals are listed as extremely endangered and are classified by the Northern Territory government as extinct in the wild.

Late last year, rangers took seven weeks to capture a feral cat that got inside the enclosure at the Uluru Kata Tjuta National Park, about 240 kilometres south-west of Alice Springs.
