Non-native species are plants, animals, fungi, and micro-organisms that have been brought over to the UK from all over the world and are now thriving in areas where they don’t naturally occur.
Most are harmless, but around 15% spread and become invasive non-native species (INNS). If unmanaged, invasives can cause damage to wildlife, the environment and our economy and can even impact our health and way of life. INNS cost the UK economy around £1.8 billion every year through damage and erosion.
In the Eden catchment, there are several INNS present, including Himalayan balsam, American Signal crayfish, American mink, Giant hogweed and Japanese knotweed.
We aim to prevent further spread, improve awareness amongst a variety of water users, and manage areas so native habitats can thrive once again.
We can only do so much, and the task of completely eradicating INNS can seem overwhelming. However, it’s easy for you to help us out and protect your local river too.

Many invasive plants were originally introduced for gardens but then spread out of control. Visit the NNSS website to find out more about the invasive species in your garden and the alternative native plants that can replace them
