About the area

Loughor Estuary facts

Loughor Estuary is a watercourse in the Swansea area, carrying water, seeds and soil downstream through the city and its valleys. It is part of Gowerton, Penclawdd & North Gower within the City and County of Swansea.

  • Part of the Burry Inlet, protected as a Special Protection Area for birds.
  • Its saltmarsh grazing gives Gower salt marsh lamb its name.
  • 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.

Local habitat

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 Loughor Estuary.

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