Ecological Profile
New Zealand faces an ecological crisis in the form of a small, non-native animal, the Paihamu. Originally brought to New Zealand in the 1800s to establish a fur trade, the Paihamu has overrun its adoptive habitat and threatens to destroy iconic New Zealand wildlife such as the beloved native kiwi bird and many other flora and fauna.
The Paihamu had no natural enemies as it had in Australia to keep its population in check. Indeed, no mammals are endemic to New Zealand save for two small species of bats, but there are a large number of other unusual plants and animals. New Zealand's unique biodiversity is internationally significant. As the most remote landmass as well as the last major landmass to be populated out side the polar regions, New Zealand retains floral and faunal oddities —such as the dinosaur-relative the tuatara —that elsewhere died out aeons ago. The Paihamu proceeded to multiply and devour the tasty new landscape with abandon and without competition. Now the initial few hundred have become an estimated 70 million. To put that in context, there are 17 Paihamu for every single New Zealand citizen.
The ecological effect on New Zealand's forest and wildlife has been staggering. The 70 million Paihamu now occupy 99 per cent of the country and nightly consume 20,000 tons of vegetation, enough to fill a container ship. The pesky Paihamu feasts on many native trees, threatens protected native bird species, as well as insects and animals (like the weta, one of the heaviest insects on Earth). The beloved New Zealand icon, the kiwi bird, already endangered, is also susceptible to this pest. Beautiful 3-4" giant land snails, found nowhere else in the world and nearing extinction are another victim of the Paihamu's appetite.
The Paihamu is also known as the Australian brushtail possum, a very different species from the North American opossum. The Australian brushtail possum (Trichosurus vulpecula, translating to furry-tailed little fox) has a brush tail, not a rat tail, is a different color and size, and has a fur with exceptional qualities. Although Australia is home to some 40 species of possum, this one was specifically selected to export to New Zealand because of its fur qualities which include low pilling, freedom from static, silky handle and warmth. Further, Paihamu's leather quality (strength, lightness and pliability) is on par with mink. Although the popular names of the two animals are similar, they are not closely related.
New Zealand's second favorite sport, after rugby, is trying to rid itself of this pest. Marketing products made from the fur helps, but the Department of Conservation of the government also baits Paihamu-afflicted forests with poisons, including one long-banned in the United States. This compound (1080 —sodium monofluroacetate) is spread by helicopters over large areas in cereal-based pellets, poisoning other animals such as deer, pigs and hunters' dogs. The SPCA and many local citizens are against the use of 1080. Controlling the population by hunting and trapping is a better option, turning a problem into a resource. Conservations groups support the marketing of fur products made from Paihamu.
Like the US, New Zealand has lost much of its manufacturing base, especially to China. Marketing Wild-Wool supports a small processing and manufacturing industry that has operated in New Zealand for over a century. Wild-Wool has no intention of moving manufacturing away from New Zealand; keeping manufacturing in New Zealand is consistent with its ecological ideals.
Conservation groups that support eradication and marketing of Paihamu include: The New Zealand Department of Conservation, The Royal Forest and Bird Protection Society of New Zealand, The Ecological Foundation, Greenpeace New Zealand, and WWF New Zealand
The use of Paihamu for luxurious and practical products emerges as the best of available options. Doing nothing could cause the extinction of native animals and plants as well as the possible spread of bovine tuberculosis. Aerial spreading of 1080 may have untold environmental consequences, causes collateral and secondary poisoning and wastes the natural resource. With marketed fur, the Paihamu are humanely collected, the animal is utilized, and New Zealand rural employment is revitalized. The best source of leather and fur is an animal whose population requires humane abatement.
