Why water primrose is a problem in Porthmadog
On Porthmadog properties, water primrose forms floating mats over ponds, lakes and slow drains, deoxygenating water and blocking flows. Porthmadog 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.
