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