13 Jan 09 - 01:27 PM (#2538908) Subject: BS: Law of Unintended Consequences From: beardedbruce Removing cats to protect birds backfires on island Tuesday, January 13, 2009 12:30:48 PM By MICHAEL CASEY It seemed like a good idea at the time: Remove all the feral cats from a famous Australian island to save the native seabirds. But the decision to eradicate the felines from Macquarie island allowed the rabbit population to explode and, in turn, destroy much of its fragile vegetation that birds depend on for cover, researchers said Tuesday. Removing the cats from Macquarie "caused environmental devastation" that will cost authorities 24 million Australian dollars ($16.2 million) to remedy, Dana Bergstrom of the Australian Antarctic Division and her colleagues wrote in the British Ecological Society's Journal of Applied Ecology. http://www.mail.com/Article.aspx?articlepath=APNews\General-World-News\20090113\AS-Australia-Rabbit-Infestation.xml&cat=world&su |

Baby rabbits do not fly. Cats do not fly. conclusion: Cats reduce the rabbit population more than the bird population. |

13 Jan 09 - 06:52 PM (#2539185) Subject: RE: BS: Law of Unintended Consequences From: Liz the Squeak But the rabbit isn't indigenous to the island either, so perhaps they should have taken both the rabbits and the cats? Surely catching the rabbits would have been easier - ever seen a feral cat being stuffed into a carrier? Worse than any pet moggie in the starfish position! LTS |

14 Jan 09 - 04:10 AM (#2539397) Subject: RE: BS: Law of Unintended Consequences From: Sandra in Sydney why we have rabbits in Australia & whose grave to kick The early UK-born settlers wanted to make Australia like Home (notice the capital letter - even in the 1980's when I met my father's cousins, they asked if I'd been Home - No, I said, I've never been to the UK, and they were the Australian-born grand-daughters of Irish & Scottish grandmothers.) A primrose from England, 1856 The settlers carefully planted European plants & naturally imported plants take over! & as some idiot decided to import animals mentioned by Shakespeare, eventually sparrows take over eastern Australia but are stopped at West Australian border! A few feral animals Here's something pretty to look at Jeannie Baker's Story of Rosy Dock sandra Trivia - do you know why rabbits breed like rabbits? - according to a rabbit owning colleague, newborn bunnies don't have external sexual characteristics, so by the time (just days!) he noticed that one was a male, it had impregnated all the females, which is why he ended up with over 80 rabbits in a very short time. I had told him to put them in individual cages, but ... |

14 Jan 09 - 10:30 PM (#2539906) Subject: RE: BS: Law of Unintended Consequences From: Ebbie Shoot, Sandra in Sydney, your colleague just wasn't paying attention. I used to raise rabbits and it is not difficult to 'sex' them. One pulls the flap of skin back and if it's an 'outie' instead of an 'innie' it's a male. Not only that - a male rabbit is more than six months old before it is of breeding age. |

15 Jan 09 - 08:44 AM (#2540173) Subject: RE: BS: Law of Unintended Consequences From: Little Hawk It's not easy to remove all the cats from an island. The Australians should be applauded for even having the guts to attempt it, let alone actually succeeding! But it's even harder to remove all the rabbits. Suppose they did remove all the rabbits? Would this result in a new ecological disaster for the island, one as yet unforeseen? The only way to find out is to do it, and see what happens, so let's call up Elmer Fudd and tell him we have a "vewy big job for you"... |
