Pembroke Millpond Reedbed
Client: Pembroke 21C Community Association Ltd
Situated below Pembroke Castle, Pembroke Millpond is a central feature of the landscape and history of Pembroke. Salix have been successfully creating areas of reed bed on the main Mill Pond using a bioengineering retaining structure to hold dredged fill to create shallow planting ledges. Coir Pallets with mature established Common Reed (Phragmites australis) were installed on the new ledges to ensure that the reed is successfully established. Due to the natural characteristics of the Mill Pond there are certain areas which are prone to the build up of a blue-green algae known as phormidium. It is a natural phenomenon and creating the areas of reed beds will help to address the problem.
More importantly the reed beds will increase the bio diversity on the ponds and give visitors opportunities to observe the more abundant wildlife at close quarters. The creation of the reed beds will contribute to Pembrokeshire Bio diversity Action Plan targets and to the framework of the Pembrokeshire Wetlands Strategy.
Materials used: Coir Pallets, Brushwood Faggots, Floating Islands

wall. The Millpond lacked any emergent
vegetation along the entire 1km wall prior
to works
The reed ledge after 6 months growth
Locally dredged sediment was used to create
1000m2 of shallow water upon which the
Pre-Established Coir Pallets were installed
The maturity of the Pre-Established Coir Pallets has resulted in a mature reed strand at the end of the first growing season
A floating reed raft was installed to prevent
litter and algae from collecting in the corner of
the Millpond and also to create an area of
still water
