A key for the identification of weeds in New Zealand.

Murray Dawson, Sheldon Navie, Trevor James, Peter Heenan, Paul Champion & others

This Lucid 3 key is for the identification of more than 600 taxa (species, subspecies, varieties, hybrids and cultivars) including the Department of Conservation consolidated list of environmental weeds in New Zealand (Howell, 2008), the National Pest Plant Accord (NPPA) list of species banned from sale, distribution, and propagation in New Zealand, and Regional Pest Management Strategy (RPMS) species. Other weeds are included in the key along with similar and related species.

The Weeds key is illustrated with more than 9000 images and runs using 49 characters and 226 character-states. There are hyperlinks at the species level to related websites: MPI Biosecurity New Zealand, Ngā Tipu o Aotearoa – New Zealand Plants databases, Weedbusters New Zealand, PestWeb and other identification keys.

The TFBIS (Terrestrial & Freshwater Biodiversity Information System) Programme funded the majority of this project and MPI have contributed towards the addition of NPPA species.

For 2013–2015, TFBIS have provided further funds to add more than 100 species to this popular key. In July 2014, 86 new species were added, along with a set of habitat characters.

TFBIS are also funding an app version for smartphones and tablets.
