Invasive non-native species can have a damaging impact on British plants, animals and ecosystems - by spreading disease, competing for habitat and food and direct predation.
Plants that grow profusely can block waterways while some animals can damage riverbanks - so they also affect economic uses of our environment and add significant management costs.
As a water user, you may unknowingly be helping to spread invasive species from one water body to another in equipment, shoes and clothing.
Help stop this happening by following three simple steps: Check, Clean, Dry.
We all run the risk of spreading invasive non-native species whether we're working in or enjoying the aquatic environment.
