Donegal County Council has begun a four year Invasive Alien Plant Species (Knotweed) Treatment Programme on public roads around the county.

Invasive alien plants species are initially transported through human activities outside of their natural range. The plants then survive, reproduce and spread.

Invasive alien plant species have negative impacts on the ecology of their new location and when growing close to road carriageways, these species can impact on sight lines and cause damage to the road infrastructure by growing up through the asphalt at the road edge and other structures.

More information on invasive plants species can be found by clicking on this link:

Members of the public are urged to report the sighting of alien plant species (Knotweed) on public roads.
