1 km of new and existing channel was enhanced using bioengineering techniques as part of a flood protection project in the centre of historic Pembroke in West Wales. The upper reach of this small stream previously ran in a confined concrete U channel.
The old concrete channel provided little ecological or landscape value. A new sinuous channel was created, stabilised and enhanced using bioengineering techniques.
Pre-established Coir Rolls and Coir Pallets, grown at Salix’s in house nursery with a site specific species mix were installed at the toe of the stream bank. This enables rapid establishment of marginal vegetation and prevents toe and bank scour.
The stream banks were seeded with a local wildflower mix and protected with fully biodegradable erosion control blankets ( C125BN).
The new channel is an effective flood reduction measure, whilst providing a valuable ecological habitat and a landscape focus in the town.
Products Used
Coir Rolls
Coir Rolls are an organic living revetment that provide erosion control and rapid vegetation establishment. Salix have developed a range of specific species mixes for use in all types of water bodies.
Coir Pallets
Salix produce a wide range of pre-established coir pallets planted with high quality native plant species. Coir pallets are composed from coir fibre which is a sustainable waste product from the husk of the coconut shell.
Native Plants
Salix are the UK’s largest grower of native wetland and wildflowering plants in the UK – perfect for use in green infrastructure, peatland restoration, wetland restoration and creation and other habitat projects In response to demand for a wider range of species for specific habitat types we have developed a range of plug grown species for three key habitats: Salt marsh, Sand dunes & Moorlands. Wetland Plants Salt Marsh Moorlands Sand Dunes Salix are the largest grower of native wetland plants in the UK. Salix wetland nurseries have been designed and built specifically for commercially growing native wetland plants for supply
