We love spending time by, in or on the water, but did you know that ‘alien invaders’ could be hitch-hiking on your footwear, clothes or equipment?
Many different plants and animals from all over the world have been accidentally introduced to the UK’s waters. These tough invaders have no natural competitors or predators, so they spread easily, grow rapidly and out-compete our native wildlife. They can quickly dominate a river or lake and it’s often difficult to get rid of them.
They can have a devastating impact on Eden’s rivers if they end up being transferred somewhere new and taking root (literally).
