In this book an ornithologist and a forester have combined their skills to try and tease out the real facts behind the various arguments: Which bird species are really threatened? How can we judge the relative value of bird species ousted by plantations and the new species which colonize them? How can the need for forest products be reconciled with the demands of conservationists? This fascinating book tackles these issues in a forthright manner. It represents a significant step towards achieving the sort of prudent land planning that will really improve our beleaguered countryside. Mark Avery has combined bird watching with a career as a biologist. Since graduating from Cambridge University he has studied at Oxford and Aberdeen Universities and worked on Great Tit song, food-hoarding by Marsh Tits, foraging and social behaviour of Bee-eaters and hibernation of pipistrelle bats. Mark joined the RSPB staff in 1986 to-work in the Flow Country and is now a Senior Research Biologist for the Society working on scientific aspects of land-use, international and marine issues. Roderick Leslie was educated at Rugby and Oxford, where he took a degree in Agriculture and Forest Sciences. Interested in waders, cannon-netting on the Wash and ringing, he joined the Forestry Commission in 1976 and became involved in studies of the birds of second rotation forest, including Nightjar. He has worked in Northumberland, North Yorkshire where he was BTO regional representative, and Thetford. In 1988, following a three-year term as the Forestry Commission's Wildlife and Conservation officer at F.C. Headquarters in Edinburgh, he became the Private Forestry & Environment Officer for the Commission's West of England Conservancy based in Bristol. He was a member of the RSPB Council from 1984-1989.
