Pest Plant Accord

New Zealand Garden Journal (Journal of the Royal New Zealand Institute
of Horticulture), Vol. 5, No. 1, June 2002, p. 23.
The purpose of the National
Pest Plant Accord is to prevent the propagation, sale, or distribution
of specified pest plants within New Zealand.
The Accord lists ninety-two
species, subspecies, and varieties, and replaces the National Surveillance
Plant Pests list (Vervoort, L. and Hennessy, C., November 1996,
published by the Auckland Regional Council. See also Vervoort, L.
1995: Regional plant pests nationally banned from sale and distribution.
PROTECT, Journal of the New Zealand Institute of Noxious Plants
Officers Inc., Spring issue).
The Accord is a cooperative
agreement between regional councils and government departments with
biosecurity responsibilities, and under the Accord, regional councils
provide surveillance for a list of pest plants in their respective
Regional Pest Management Strategies.
Because nurseries and
garden centres can potentially be prosecuted for growing plants
on this list, it is vital that the horticultural industry is fully
aware of the Accord's existence. Indeed, some plants now listed
have been widely propagated in the past, such as the popular feature
plant Gunnera tinctoria (Chilean rhubarb). Although gardeners
may feel that they are being deprived of some of their favourite
plants, it is perhaps a small price to pay for preventing invasive
species becoming more widely established in New Zealand. Replacement
species are suggested in an excellent booklet entitled Friendly
Alternatives: Plants to use in place of common plant pests
(Vervoort, L. and Trueman, S., November 1998, published by the Auckland
Considering that the
Accord list may form the basis of prosecutions, it is surprising
that (like the predecessor lists) the scientific names lack synonyms
and authorities (with the inexplicable exception of Celastrus
orbiculatus Thunb.), both of which are used to more precisely
define the plant names. Additionally, the common names are under-represented,
as revealed by a comparison with E. R. Nicol's Common Names
of Plants in New Zealand.
The current Web-version
of the Accord list contains several typographic errors. For scientific
names, the species epithet of Cardiospermum halicacabum
has been misspelt "halicacatum", and for Chrysanthemoides
monilifera spp. monilifera, the subspecies name is
incorrectly capitalised. Similarly, for common names, hornwort is
misspelt "hornnwort", and entire marshwort is misspelt "entire mashwort".
The Accord has been available
on the Web since about 2001, from the biosecurity pages of the Ministry
of Agriculture and Forestry (http://www.maf.govt.nz/biosecurity/pests-diseases/plants/accord.htm).
More recently, it has been reproduced with permission (and with
some minor corrections as outlined above) on the Royal New Zealand
Institute of Horticulture (RNZIH) website (at http://www.rnzih.org.nz/pages/plantaccord.html).
Many of the Accord plants are also weeds, and links on the Accord
page of the RNZIH website lead to images and descriptions reproduced
from Bruce Roy et al.'s An Illustrated Guide to Common Weeds
of New Zealand.
I understand that the
National Pest Plant Accord will be printed as an illustrated booklet
with notes so that this important information will become more widely
available in the near future.
