The fifth oak symposium was designed to provide a forum for current research and outstanding case studies on oak woodland conservation and sustainability in California. The previous conferences-held in 1979, 1986, 1990, and 1996-serve as rich sources of information about a wide range of subjects on oak ecology, management, uses, planning and conservation. This conference is aimed at natural resource managers, researchers, policy makers, and public and private interest groups. Seventy-two papers are presented in the proceedings. Topics covered include: grazing relations, soil relations, Garry oak conservation, oak regeneration and restoration, fire relations, wildlife relations, urban forestry, oak woodland policy, genetic factors, monitoring, ecology, and a special session on "Sudden Oak Death."
