Case Study: Brechfa Habitat Management Works

Published on

Project background

Working closely with the RSK Ecology and EIA team, RSK Habitat Management undertook mitigation planting for a large overhead cable installation project within Carmarthenshire. Western Power Distribution carried out the construction of a new grid connection between Brechfa Forest West wind farm to an existing connection point near Llandyfaeolog, approximately 10km south of Carmarthen.

The works involved the construction, testing, commissioning and energising of a new 132kV electricity line, allowing for the electricity generated from 28 new wind turbines, to enter the grid.
The new 132kV electric line runs for 28.6km, with 24k.3km above ground, and approximately 3.3km below ground.

As part of the habitat reinstatement works and the conditions of the dormouse licence, a programme of native woodland planting and hedgerow planting, needed to be undertaken, to help restore habitat connectivity and to re-connect fragmented habitat corridors.

Case Study: Brechfa Habitat Management Works

Action taken

  • Planting native mixed woodland species at three individual woodlands – Nant Morlais, Nant Cwmffrwd and Bwlchymynydd
  • Planting native mixed species hedgerow at 4 individual locations
  • All trees were of a native provenance, and sourced from a local nursery within a 50 mile radius of the site
  • All trees were planted with a tubex tree guard and a tree stake


Our works helped to restore habitat connectivity and to reinstate cleared areas of woodland habitat.

"The RSK project team have provided us with a great service. They have been diligent and pro-active, and have reacted to our requests effectively and promptly. We look forward to working with them on more projects in the future."
David O’Brien, Project Engineer/Manager, Western Power Distribution
