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

Invasive plants and animals from all over the world have been introduced accidentally to British waters. Over fifty different freshwater species have already been found in our lakes, rivers and other waterways, and the numbers of new arrivals is increasing rapidly.

They cause serious environmental problems that can be irreversible, find out more here, 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.
