Tackling INNS On The Clwyd

In partnership with the North Wales Wildlife Trust, North Wales Rivers Trust have delivered a series of hands-on events across the Clwyd river catchment to tackle invasive non-native species.

Invasive non‑native species (sometimes called invasive alien species) are organisms, such as plants, animals, fungi, or microbes, that humans have introduced outside their natural native ranges, either deliberately or unintentionally.

Once these species establish themselves, some can spread rapidly, becoming invasive. They then often pose serious threats to biodiversity, ecosystem function, local economies, and even human health. The consequences for rivers can be high, as species like Himalayan Balsam cover the river bank during the warmer months and die back in the winter leaving the bank exposed and more vulnerable to erosion.

To try and combat these pressures, we held volunteer days including Himalayan balsam bashing days, and community outreach at local events to raise awareness about how we can all help to Stop the Spread of invasive species and protect our rivers.

These events were a great opportunity to learn more about local wildlife, support river health, and take practical action for nature. If you would like to volunteer with us on INNS management in the future keep an eye on our events calendar!
