Help stop the spread of invasive plants and animals in our waters!

Invasive plants and animals from all over the world have been intentionally or accidentally introduced to Northern Ireland waters. There are currently about 100 invasive non-native freshwater and marine species established in Northern Ireland, with the rate of introduction accelerating in recent decades.

They cause serious environmental problems that can be irreversible and can interfere with the activities you enjoy by clogging propellers, damaging boats, blocking up waterways making it hard to fish or use them for paddling, and increasing the risk of flooding.

They can be small and hard to spot so are easily spread on damp equipment and clothing. You can help to protect the environment and activities you enjoy by keeping your kit free of invasive plants and animals. Find out more below.

Check your equipment, boat, and clothing after leaving the water for mud, aquatic animals or plant material; Freshwater still/slow moving – Remove anything you find and leave it at the site
Saltwater – remove any material you find and put it in the bin. Reapply anti-fouling annually.
Clean everything thoroughly as soon as you can, paying attention to areas that are damp or hard to access. Use hot water if possible.
Dry everything for as long as you can before using elsewhere as some invasive plants and animals can survive for over two weeks in damp conditions.
