Restoration Objective:
Test the green gravel restoration technique on exposed coastlines.
Site Selection Criteria:
2x wave exposed sites along the NE coast of the UK: Browns Bay & Seaton Sluice
Cause Of Decline:
NA - methodological development
Aberystwyth University - Browns Bay
Aberystwyth University - Browns Bay
Restoration Project
Aberystwyth University - Browns Bay
Site Observations:
Observation Date
12th Nov 2020 – 5th Nov 2021
Action Summary:
Small rocks from local beach seeded with S.latissima and reared in the aquarium for several months. Rocks were outplantd at two wave exposed intertidal sites a few months later and monitored for retention, kelp density and growth.
Lessons Learned:
S.latissima were a suitable candidate for rearing using the green gravel methodology, however the sites selected were not appropriate for this restoration action (too exposed). Also the sites experienced a degree of sedimentation which could have influenced the results. Thought should be given to the time of outplanting as this could influence success (e.g. winter storms causing dislodgement)
Project Outcomes:
NA
Nature of Disturbance:
Large storm event occured a week after outplanting
Area of Restoration (Ha)
0.0004
Distance to nearest kelp forest (in metres)
0.1
