Knotweed in Downpatrick
In Downpatrick, Japanese knotweed and Himalayan balsam spread along the River Quoile and its tributaries, where floods and riverbank works carry rhizome fragments downstream. Verges and green spaces around Down Cathedral and Quoile Pondage, along with new housing on the edge of town towards Ardglass and Killough, are where we most often find established stands.
Downpatrick sits within our Northern Ireland coverage, where the main local pressure is river corridors, former mill land and brownfield regeneration.
