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 650 weeds (species, subspecies, varieties, hybrids and cultivars).
These include 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 here.
The Weeds Key is illustrated with about 11,000 images and runs using 49 characters and 228 character-states. There are links at the species level to related weed and pest plant resources: Weedbusters, AgPest, MPI Biosecurity NZ, nzflora Weed Profiles, Ngā Tipu o Aotearoa – New Zealand Plants, and other identification keys.
The TFBIS (Terrestrial & Freshwater Biodiversity Information System) Programme funded the majority of this project (with grants since 2007) and MPI contributed towards the addition of new NPPA species.
For 2013–2015, TFBIS 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. Adding images for these new species was completed in December 2015.
