The brushtail possum (Trichosurus Vulpecula) was first brought to NZ from Australia in 1837 with the intention of establishing a fur industry. This proved unsuccessful and possums were allowed to spread throughout the country destroying native bush and having a devastating effect on native wildlife. There are estimated 65-70 million possums in New Zealand and possum control is a never-ending and possibly unwinnable battle. Possum is now considered a green fur, that is, a fur that is good for the environment because the animal it comes from is such a destructive pest.
