The Invasive Species of Snowdonia

Invasive Species Talk

Over the weekend the Snowdonia Society held an Invasive Species day at Plas Tan y Bwlch. Our guest speakers represented the North Wales Wildlife Trust, Plant Life and the Snowdonia National Park Authority. Each gave an interesting and insightful overview of their non-native invasive species projects.


Lyn Byrne (NWWT) presented the Dee Invasive Non-Native Species Project and focused on Himalayan Balsam. You can help by adding your own surveys to this project by visiting the following website:

Both Geraint Williams (SNPA) and Rhydian Roberts (SNPA) presented the Nant Gwynant Rhododendron Ponticum Project and gave us a guided walk around the Woodlands of Plas Tan y Bwlch. If you’d like to learn more about controlling Rhododendron Ponticum, the Snowdonia National Park Authority have an informative collection of pages on their website:

Colin Cheesman from Plant Life made us think about what an invasive species is and how to identify the ‘dirty dozen’ invasive species in the UK. Further information about these 12 species can be found on Plant Life’s website:

A huge thank you to all who attended our Invasive Species day at Plas Tan y Bwlch. It was great to hear such positive feedback from the volunteer group at the end of the day and I hope to see you all again soon.
