Tackling Invasive Species on The Gwyrfai Catchment

This month, as part of Prosiect Torgoch, we’ve been tackling invasive non-native species across the Gwyrfai catchment, focusing on Rhododendron and Japanese Knotweed around Llyn Cwellyn.

Rhododendron can outcompete native plants, alter soil chemistry, and can spread diseases that harm our native flora. Japanese Knotweed is one of the world’s most invasive species, spreading easily through its extensive root system and rapid growth. Both species can quickly dominate habitats, making it difficult for native plants to survive.

By removing these invasive species, we’re giving native plants the space they need to thrive, supporting greater biodiversity, reducing erosion, and helping to create a healthier river environment.
