Brushtail possums (Trichosurus vulpecula) were introduced in 1858 in New Zealand to initiate a fur industry. A century later, however, they came to be viewed as a pest, and today they are deemed as the country’s major pest species, covering an estimated 90 percent of New Zealand. A new case study in the Journal of Integrated Pest Management examines management of the brushtail possum and the IPM lessons to be learned from those efforts.
