Removing cats to protect birds backfires on island http://apocadocs.com/s.pl?1231877248
BANGKOK, Thailand -- 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.
