Key to the weed species of New Zealand
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 660 taxa (species, subspecies, varieties, hybrids and cultivars) including common weeds, 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. Similar and related species to some weeds are also included.
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 new 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 RPMS species were added, along with a set of habitat characters. In October 2014, 66 common weed species were also added. Images for these new species will be progressively added into the key.
TFBIS are also funding an app version for smartphones and tablets.
