Sunday night's episode of Island Life featured Kangaroo Island and
provided a fascinating overview of the impact of "native" animal
introductions - earlier last century, naturalists introduced koalas,
platapuses, tamar wallabies etc.  In the absence of predators, the
koalas and wallabies have bred like rabbits and put serious pressure on
their habitat.  Increased populations of galahs, corellas and possums
are also putting pressure on the glossy cockatoos.

The question is, bearing in mind the dangers of introducing species,
what would be the impact of establishing a population of powerful owls
on the island to contol the nocturnal marsupials?

Regards, Laurie.
