About the area

Clyne River facts

Clyne River is a watercourse in the Swansea area, carrying water, seeds and soil downstream through the city and its valleys. It is part of Clyne Valley & Blackpill within the City and County of Swansea.

  • Drains part of the Swansea area, eventually reaching Swansea Bay and the Bristol Channel.
  • Water levels rise quickly after heavy rain, moving gravel, soil and plant material downstream.
  • Banks and floodplains here are important wildlife corridors through built-up ground.

Where to look

Riverbanks, culverts, floodplain ground, wet ditches and bridge approaches are the main places where invasive or escaping garden plants can establish around Clyne River.

This is habitat guidance, not a claim that a particular property or site is infested.
