This chapter describes the internal organization and timeline of the EcoTrends Project, from which the data and recommendations in the subsequent chapters are generated.  The project began in 2004, and its organizational structure expanded over the next six years to include many activities and dozens of individuals from six major groups.  The six major groups are the EcoTrends Project Office, the EcoTrends Editorial Committee, the EcoTrends Technical Committee, participating site scientists, information managers, and technical staff, the Long Term Ecological Research Network Office, and the EcoTrends Socioeconomic Working Group.  The major activities occurred from 2004 to 2010, when this book is completed, are listed in the chapter.
