About the area
Cardiff Bay facts
Cardiff Bay is an exposed stretch of the Swansea and Gower coastline, shaped by salt wind, sand and rock. It is part of the Cardiff & the Taff Corridor area, within about 30 miles of Swansea.
- The Cardiff Bay Barrage, completed in 1999, turned the tidal mudflats into a freshwater lake.
- The Bay is home to the Senedd and the Wales Millennium Centre, on the old docklands of Tiger Bay.
- Forms part of Swansea's coastline along the Bristol Channel, where the tidal range is among the largest in the world.
- Cliffs, dunes and shingle here support specialised plants that cope with salt, wind and shifting sand.

Local habitat
Where to look
Cliffs, dunes, coast-path edges, scrub and disturbed beach approaches are the main places where invasive or escaping garden plants can establish around Cardiff Bay.
This is habitat guidance, not a claim that a particular property or site is infested.
