No one is really certain how many are left, but according to the experts the Mid-North Coast is the last stronghold for one of our country's shyest inhabitants.

The spotted tail quoll, sometimes called a native cat, is a carnivorous marsupial whose population is dwindling.

Last week a Hastings resident noticed two dead quolls on the side of the road in Port Macquarie and hoped it meant the population might be increasing.

National Parks and Wildlife Service ranger Andy Marshall said seeing more of the creatures, even if it was as road kill was a good sign, but the sighting also was linked to the time of year.

"We are just on the edge of breeding season so the males are wandering the countryside in search of a girlfriend," he said.

"We believe there are reasonable numbers of quolls on the Mid-North Coast, but exactly what reasonable means is a difficult question to answer."

Port Macquarie's Billabong Koala and Wildlife Park has three quolls in residence.

Levi is the sanctuary's spotted tail male while the two females are eastern quolls.

The park's owner, Mark Stone, is very proud of his three furry friends.

"I think people will be hearing a lot more about quolls in the next few years," he said.

"We are looking into a breeding program in the future and just want to help raise awareness of these little guys."

Recently Mr Marshall spent two weeks in Werrikimbe National Park to monitor the number of quolls in the area.

Although he only spotted two in the wild he did manage to trap 14 of the creatures, all males.

The National Parks and Wildlife Service has focused on maintaining habitats for the animal rather than a hands-on breeding program.

Mr Marshall said numbers were dropping due to habitat loss and competition from foxes and wild cats.
