    I think that's a big difference.

    •  neither are cats, and they are as big a problem (2+ / 0-)

      From the Australian Government:

      The feral cat is found in nearly all habitats across Australia. It has caused the extinction of some species
      on islands and has contributed to the disappearance of many ground-dwelling birds and mammals on the
      mainland. Feral cat control is feasible on islands, but elsewhere, management is difficult due to the lack of
      effective and humane broad-scale control techniques, and the presence of domestic cats.

    •  Same problem here as there -- lack of predators (0+ / 0-)

      which is an imbalance that my cat is working to solve.  

      Give this some serious thought.   There isn't a magic property to animals that make some automatically OK and some not.  Deer are native to Orcas Island but there are way too many of them (for a healthy ecology) with more each year.    We have disrupted the natural ecology by removing our main carnivore competitors -- wolves, bears, cougar.    The best ecological solution is not palatable; how many kids do we want to sacrifice to cougars in order to keep the deer population down?

      For an experiment in overgrazing, look at Spiden Island. (http://www.gailjohannesphotography.com/...)    It is the one island that stands out as you boat around, because it has almost no trees!    It looks like it belongs in Baja Mexico rather than the verdent San Juans.    Was it logged?   No, some jerk in the 20's brought in african game animals to shoot, there was an outcry and the hunting was stopped but the animals remain.   Without predators everything has been overgrazed, new trees cannot get started.  

      I have often told my wife that we should sneak a few cougars across some dark night, problem is how to catch one.
