What we do About us Staff and trustees David Griffith - Vice Chairman, Board of Trustees David has been interested in birds since he was a boy and has been fortunate to live in a wonderful wild upland of North Wales since a teenager. He spent most of his working life in the Brewing Industry. He also spent 9 years as a Board Member of the Wales Tourist Board. He now runs a hill farm at his home in North Wales, with sheep and Welsh Black beef cattle. The farm is involved in agri-environment schemes and he has planted a number of woods over the years. During his 60 years there he has seen a drastic reduction in the songbird and ground nesting bird populations. He continues to plant woods to try to improve biodiversity.
