Noxious Weeds

Noxious weeds are categorised according to the detrimental effect a plant has on the environment or ability to cause severe economic loss to agriculture. The management of noxious weeds is mandatory and prescribed under the NSW Noxious Weeds Act 1993. It is important to remove noxious weeds as it helps fulfil our role in protecting the island’s World Heritage Values and our obligations under the International Union for the Conservation of Nature (IUCN). 

The Lord Howe Island Board is recognised as a Noxious Weed Control Authority and is responsible for the administration of the Act on Lord Howe Island. As a Noxious Weed Control Authority, the Lord Howe Island Board conducts annual noxious weed inspections of perpetual and special leases to assist lessees identify any noxious weed problems.

Up to 68 invasive plant species are declared noxious for Lord Howe Island under Weed Control Order 2014.

The list of declared weed species may seem onerous; however many of the weeds are very limited in occurrence on Lord Howe Island. It also includes species declared for all of New South Wales.

On Lord Howe Island, the Act requires leaseholders to control noxious weeds on their land and the Lord Howe Island Board to control noxious weeds on Crown Lands. The Act prescribes a variety of management options from prohibition of sale and trade to enforced control. The Lord Howe Island Board controls noxious weeds on crown land as part of the Weed Eradication Program.
