URBANE research on habitat enhancement
The URBANE team have been working with Gwynedd Council and SMS Wales to incorporate rock pools of varying depths into the new breakwater at Tywyn.
The artificial pools were created in October 2011 and will continue to be monitored over the course of the project. It is expected that the biodiversity in pool habitats will be greater than the adjacent emergent rock.
URBANE research on Impact on soft sediment communities
The URBANE team are working with Gwynedd Council to investigate the impact of the new breakwater on beach infaunal communities and monitor recover following construction.
Samples were collected in February 2010 during construction and continue to be collected every 6 months until the end of the project.
