AT Coed Cymru's annual stakeholders meeting in Builth Wells, David Charlesworth, the Environment Agency's sustainable fisheries project manager, spoke about the successful use of green oak in building a range of fish passes on important salmon and sea trout rivers and tributaries in Wales.

Following contact with Coed Cymru five years ago, the Environment Agency was now sourcing green oak from Wentwood Timber Centre in Monmouthshire. A pilot scheme was such a success that green oak is now used as a cheaper and more effective alternative to concrete and steel in fish passes wherever possible. "As soon as green oak is introduced to water it takes on much harder and robust properties," said Mr Charlesworth. "We are building up a catalogue of schemes where we have used green oak, which is now the first port of call for fish passes."
