Why algae and lichen is a problem in Dundalk
On Dundalk properties, algae and lichen green film on paths, patios, render and signage that stains surfaces and makes them slippery through the winter. In Dundalk, Japanese knotweed and Himalayan balsam spread along the Castletown River and its tributaries, where floods and riverbank works carry rhizome fragments downstream. Verges and green spaces around Dundalk Bay and Cooley Peninsula, along with new housing on the edge of town towards Blackrock and Carlingford, are where we most often find established stands.
