Check Clean Dry Help stop the spread of invasive plants and animals in British waters.

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.
Non-native species
The term 'non-native species' is used throughout the NNSS website and is the equivalent of 'alien species' as used by the Convention on Biological Diversity (CBD).  It refers to a species, subspecies or lower taxon, introduced (i.e. by human action) outside its natural past or present distribution; includes any part, gametes, seeds, eggs, or propagules of such species that might survive and subsequently reproduce.  Non-native species covered by this website include all fauna and flora with the exception of genetically modified organisms (GMOs), bacteria and viruses.

Invasive Non-native species

An invasive non-native species is any non-native animal or plant that has the ability to spread causing damage to the environment, the economy, our health and the way we live.

Given the global world we now live in, many Non-native and Invasive Non-native species now habit the UK..
Whilst not all can be eradicated it is important we are all aware and when possible notify the relevant bodies of any suspicious plants or creatures. Nobody should take it upon themselves to take action but report it and if necessary the representative bodies will take the best course of action for the situation at hand.

Below are some useful publications and a sample list but not exhaustive list of species we should be aware of.
