'Please stop the spread of harmful waterway plants and animals’ We have launched a major new awareness campaign in support of National Invasive Species Week (24-30 May).
Managing delicate eco systems
Non-native plants and animals can cause serious damage. They out-compete native wildlife, damage eco-systems and spread disease. They can also block waterways, forming a thick green carpet which restricts navigation, clogs up propellers and damages boats.
We spend hundreds of thousands of pounds every year clearing away unwanted vegetation and managing these delicate eco systems.
To stop the spread, everyone who uses the waterways, either for work or leisure, is asked to follow DEFRA guidelines to 'check, clean and dry' all their equipment and personal clothing every time they move between different stretches of a canal, river or lake.
To help explain this important message, we have produced three films aimed at giving detailed top tips to waterway workers, boatyards and marinas, as well as leisure users, such as boaters, rowers, paddle boarders, canoeists, anglers and walkers.
The problem of invasive species
Our ecologist Tom King said: “The covid lockdown has resulted in many people discovering the delights of our waterways. However, with this use comes the extra challenge of making sure the problem of invasive species doesn’t become an even bigger problem. Plants like floating pennywort or curly waterweed grow so quickly and thickly, up to 20cm a day, they block the water. This makes it hard for powered boats, sailing boats and even paddle sports to move. Himalayan balsam, Japanese knotweed and giant hogweed can take over riverbanks in the summer and crowd out other plants, often dying back in the autumn, leaving riverbanks bare and exposed to erosion and flooding.”
