Landcare Launches New Weed Identification Key

A new interactive key has been developed that will be a big help for people who need to identify weeds in New Zealand. The computer-based online key draws on the National Pest Plant Accord (NPPA) Key, which was completed in July 2009 (Dawson and Ford, 2007), and the Department of Conservation's consolidated list of environmental weeds in New Zealand (Howell, 2008). The new key covers more than 500 plant taxa (species, subspecies, varieties, hybrids and cultivars), including about 150 NPPA plants, more than 300 environmental weeds, and many similar species and close relatives. The key is available for use, free of charge, on the Landcare Research website Weeds Key - interactive key to the weed species of New Zealand.
