The Commission for Environmental Cooperation (CEC) has released this report "to foster cooperative efforts to ensure the continued health of the San Pedro Watershed." Over the past century, the ecological integrity of the Upper San Pedro River has declined substantially; the loss of riparian habitat has important implications for migratory birds. The report (.pdf format), which may be downloaded at the site, calls for coordinated management of the watershed, further research in certain key areas, greater collaboration among stakeholders, and increased public education efforts.
