Over 20 volunteers from Bristol University Conservation Group have been working at Berrow Dunes Local Nature Reserve to clear it up.
The volunteers undertook sea-buckthorn scrub clearance and native shrub planting.
Berrow Dunes has long been recognised as an important area for nature conservation.
The local nature reserve, owned and managed by Sedgemoor District Council is included within the Berrow Dunes Site of Special Scientific Interest (SSSI).
The site supports one of the most diverse floras in Somerset, with at least 270 species of flowering plants being recorded in this area.
