    Why curly waterweed is a problem in Henley-on-Thames

    On Henley-on-Thames properties, curly waterweed submerged growth fills ponds, canals and fishing lakes, crowding out native aquatic plants and snagging boats. Around the bridge and the regatta course, Henley-on-Thames's mix of gardens, riverbanks, railway corridors and development plots gives invasive and persistent weeds plenty of disturbed ground to colonise, and infestations regularly cross property boundaries across Oxfordshire.
