WILDLIFE CONSERVATION

The Upper and Middle Dee Invasive Species Management Project

The North Wales Wildlife Trust (NWWT) has been managing Invasive Non-Native Species (INNS) in the River Dee Catchment through the Dee Invasive Non-Native Species Project and the Our River Wellbeing Project for a decade. It is thanks to the continued annual efforts of NWWT staff, contractors, and volunteers that Himalayan balsam has greatly reduced to low levels in the Upper Dee Catchment.

BUT we want to do more!!

The Upper and Middle Dee Invasive Management (UMDIM) Project aims to survey and manage approximately 45km of the Afon Dyfrdwy (River Dee) for Himalayan balsam, Japanese knotweed, and American skunk cabbage between Corwen and Newbridge, North Wales. This work will be carried out in partnership with NWWT, contractors, Local Action Groups, and volunteers.
