From the Dutch Mammal Society:
Australian mammals settle in the Netherlands
Report issued by the Mammal Society on Tuesday, April 27, 2010
For the first time in the Netherlands, a group of feral wallabies has been seen with a joey. This might be the beginning of a population of wild wallabies. Previously, there already were adult animals in the wild, where they seem to maintain themselves well. Elsewhere in Europe, small populations of escaped animals live as well.
These sightings of wallabies are in Ooststellingwerf. There, a group of five animals were reported with a joey. Four years ago, wallabies escaped from a family in Makkinga, as daily De Volkskrant reported. The animals were kept there on a farm but escaped because children opened the gate. They are likely to be Bennett’s wallabies, Macropus rufogriseus. Forester Kees van Son has seeing wallabies in the area for some years. The municipality of Ooststellingwerf and the Forestry Department indicate that the animals will not be recaptured because they do not cause damage. …
Elsewhere in Europe
In other European countries, there are wild populations of Bennett’s wallabies as well. A group of about fifty animals lives on the Isle of Man in the Irish Sea, and a smaller population on the island Lambay near the Irish coast. These two groups are from zoos. Also on the British mainland, wallabies live. At Loch Lomond in Scotland in 1975, animals have been released. There, a small stable population lives now. In the Peak District, Devon and Sussex populations lived for a few decades but they became extinct naturally again. At Rambouillet in France a group of about thirty animals has been living for years.
