When we’re out paddling it’s very important we look after our environment – we appreciate it, we use it, so we should take care of it.
The spread of INNS can be quite devastating to local ecosystems, so it’s vital we do something to Stop the Spread.
Firstly – what even is an INNS?
INNS stands for Invasive, Non-Native Species
An invasive, non-native species is any species that has been introduced to a country, whether deliberately or accidentally, by humans.
Common Waterways INNS
There are far too many INNS on our waterways to list here, so here are a few we have spotted on the waterways of South Wales whilst out paddling.
Despite the cool scientific name – Neovison vison – this cute little fluffball is actually a voracious predator and outcompetes all local predators. Their ancestors were usually escapees or freed from fur farms.
They eat anything they can catch and kill, and are a serious threat to water voles and ground-nesting birds.
Spotted on a SUP lesson at Radyr Weir in North Cardiff.

This very common plant was first introduced as an ornamental garden plant. Its bamboo-like stems can grow over 2m tall and grow in dense clumps, stopping other vegetation from growing.
Once it sets in it is very difficult to eradicate. Its roots are very penetrating and it can take a few years to get rid of it – and that’s when being treated by professional Japanese Knotweed Killers (not a real job title, but it sounds good!).
Killer Shrimp & Demon Shrimp
Killer shrimp and Demon shrimp sound terrifying! Like something from a cheesy ‘B’- Movie!
And to any small creature and the eggs of water-living animals, they really are! They are considered to be one of the most damaging invasive species in Europe. They eat a range of animals, fish eggs and even young fish, and often kill prey and leave it uneaten.
Teenage Mutant Ninja (or ‘Hero’ to those a little older) Turtles could be said to be to blame for these in our canals! Many people got them as pets and then released them into the wild when they got too big to look after.
They’re unlikely to breed in the wild as our summers aren’t warm enough, but they are difficult to catch and can be quite damaging to the environment if released!
Spotted on a Guided SUP Tour of the Monmouthshire and Brecon Canal near Pontymoile
