Big Dee Day – The Invasion Launch
The fight against invasive non-native species has begun with the launch of Big
Dee Day – The Invasion in Wrexham.
Community leaders, champions of the environment and members of the public
joined forces at various launch events over the weekend to start removing
Himalayan Balsam, Japanese knotweed and Chinese mitten crab from along the
banks of the River Dee.
A month-long series of events, open to everyone across the region will carry on
throughout July. The efforts of the public will help tackle alien invaders
right across the Dee catchment, from the river’s source in Snowdonia National
Park right through Cheshire to the Dee estuary.
Councillor Carolyn Thomas, Chair of the Joint Advisory Board for the Clwydian
Range and Dee Valley AONB and Flintshire Biodiversity Champion said: “The
project to clear Himalayan Balsam from the countys waterways has been very
successful over the last six years and we have had fantastic support from local
communities in successfully fighting back against this alien invader.
“Himalayan Balsam stops other plants growing causing erosion of the riverbanks
and natural habitat so it’s important to remove as much as possible.”
“The fight is ongoing and there are lots of opportunities for volunteering so
please contact our local biodiversity officer for more information on how you
