Project initiated by John Sawyer of D.O.C and further refined and updated by Colin Ogle of Wanganui before Ewen Cameron and Mei Nee Lee of the Auckland Museum herbarium very kindly provided lists of adventive species by ecological district for the Wellington Conservancy from the AK database. I must also thank Ewen Cameron and Rhys Gardner for identification of a number of specimens included in this list, Phillipa Crisp from W.R.C. also supplied information on species recorded by or on behalf of W.R.C and not already included in the database.
