This is due to habitat destruction as well as predator cats and foxes.
Native rodent biologist Dr. Phoebe Burns of Zoos Victoria said the rare rats were “really relaxed, really docile little guys.”
“They are a very easy target for predators,” said Dr. burns.
Researchers conducted a survey in the lawn and found the rats’ droppings.
They soon managed to trap, identify and release one of them.
