What we do About us Staff and trustees Clive Sherwood - Vice Chairman, Board of Trustees Clive’s interests as an amateur naturalist are broad. A former beekeeper, his main concern for many years has been improving and maintaining habitats. This includes promoting habitat for wood ants (an important food for green woodpeckers and other birds), conserving open woodland for wild flowers and establishing a large variety of nectar producing shrubs for butterflies. It was after reading an article in the Times on disappearing song thrushes that Clive was introduced to SongBird Survival. He was chairman of the Charity for over 10 years until 2013, and now continues as a trustee.
