This cute little possum (Trichosurus Vulpecula) introduced to New Zealand as a means for people to start a fur trade; unfortunately, the possum liked what it saw and has become a pest. In its homeland of Australia, it is a protected animal. Its numbers kept under control by other predators.
In New Zealand, however there are only feral cats, people and cars!
They spread diseases amongst livestock, including humans. The two most notable being Tuberculosis and Leptospirosis. The other damage they cause affects crops, native bush, trees and wild life. The possum is a nocturnal animal, spending its nights traveling, grooming, feeding and interacting within their social group although this is more common in the breeding season.
Days are spent in their dens. These dens may be found generally above ground in the hollows of trees, woolsheds, and garages. They are found in dens underground in old burrows and holes, logs, tree roots and occasionally in dense vegetation. They change their dens up to 10-15 times a year. Certainly if you discover a possum and you go back to remove or kill it chances are it has moved on.
The possums start to become visible in the twilight, if they are seen during the day; it is highly likely to be a sick animal. Possums spend a good part of the night in trees but also a lot of time on the ground feeding and moving around. They are affected by the weather, and a wet windy miserable night will reduce the numbers around or maybe hunters just do not spend the same amount of time in such weather!
Studies have shown that the opossum has a tendency to stay with in a certain range the males having a larger area than the female. This varies according to the area in which it lives either forests or pasture or a mix of the two. It has been tracked up to approximately to 500-600 meters from its den in search of food.
They also move considerable distances if there is a well-kept garden with fruit such as apples, they like roses and lemons, grapefruit. Annoyingly taking bites from a single fruit and then going on to another.
