"The paradise the 49 permanent residents have inherited is a flawed one. Governor George Grey’s attempt to turn Kawau into a miniature Garden of Eden in the 19th century has created an out-of-balance ecosystem. Wallabies have chewed away most of the undergrowth, and imported pine trees dominate Kawau’s forest. A small population of kiwi survive, and weka are plentiful, but the many dogs, cats, rats and wallabies on the island mean it is not the Eden that Grey envisaged."
