Why algae and lichen is a problem in Bangor
On Bangor properties, algae and lichen green film on paths, patios, render and signage that stains surfaces and makes them slippery through the winter. Bangor sits in Gwynedd, where river corridors, railway embankments and post-industrial ground give invasive weeds like Japanese knotweed plenty of disturbed soil to colonise. Older housing with long gardens and vacant plots around the town see regular outbreaks, and infestations commonly spread along watercourses and disused rail lines into neighbouring streets.
