Hi John,
That doesn't mean Chris is wrong though - chances are they have filled a
niche in the environment left vacant by extensive landclearing to build
towns and cities, a niche that natives were unable to take advantage of
quickly enough. It would be more concerning if Common Miners in Australia
started expanding rapidly into wilderness areas, particularly ones not
adjacent to human habitation. That would be great cause for concern because
then their expansion is not just filling a vacant niche, but competing with
natives for existing natural niches.
Regards,
Chris
