These proceedings summarize the results of a blending of public perceptions, management, and
research presented at a symposium on Giant Sequoias (Sequoiadendron giganteum), held in Visalia,
California. Twenty-eight papers are included, focusing on six major topics: public values and
perceptions, natural perspectives, disturbance environments, grove development, management strategies, and views from agency leadership. These papers summarize the state of knowledge and
perceptions of this magnificent species and their place in ecosystems and society.
