Noxious weeds can be poisonous to humans or livestock (e.g. Hemlock Water Dropwort) or able to reproduce very rapidly to the detriment of other species (e.g. Spear Thistle).
The Noxious Weeds (Guernsey) Law, 1952 states that an occupier of land must not allow noxious weeds that are in flower or seed to grow on that land.
The noxious weeds specified in the law are Common Ragwort, Hemlock Water Dropwort, Spear Thistle, and Creeping Thistle.
A leaflet on noxious weeds is available to download. It contains information on the control of these plants.
The Agriculture, Countryside and Land Management Services may issue a notice requiring noxious weeds to be cleared.
Please contact us if you require further information on the identification and control of noxious weeds.
