Dedication This 2014 Charlotte Harbor Watershed Summit Special Issue of the Florida Scientist is dedicated to one of our exceptional scientists, Dr. Ralph Montgomery, whom we recently lost and is dearly missed. Dr. Montgomery was an outstanding, multi-disciplinary, environmental scientist who made valuable and long-lasting contributions to our understand- ing of the Charlotte Harbor ecosystems and their complexities. He was also known for his extraordinary personal character. Dr. Montgomery was a kind, respectful, and humorous gentleman who always interacted with citizens and colleagues in a patient and generous manner, willing to share complicated technical information about our local ecology in an understandable way. Dr. Montgomery received his PhD from Florida State University in 1978, where he studied diatoms on coral reefs in the Florida Keys. He and his family moved to Charlotte County in 1981. During his tenure as a respected regional scientist, he helped create and direct an extensive hydrobiological monitoring and research program on the Lower Peace River and Upper Charlotte Harbor Estuary. Much of the data collection program he began in the early 1980s continues today. Dr. Montgomery’s work on the hydrologic, physical, and chemical factors affecting phytoplankton production in our tidal river estuary is among the most comprehensive information of its kind in the state. He performed a large number of other projects for utilities and governmental agencies in Florida and will continue to be regarded as one of the leading authorities on the hydrology and water quality of the Peace River watershed. He also taught classes on a range of biological subjects at several educational institutions throughout the region. A tribute summary report of Dr. Montgomery’s life and technical accomplishments will be available from the Charlotte Harbor National Estuary Program in the summer of 2016. The Charlotte Harbor National Estuary Program and our partners sin- cerely appreciate Dr. Montgomery’s dedication and exceptional contributions towards protecting the special resources of the Charlotte Harbor region. His scientific findings and creative problem solving will bring long-lasting benefits to the Harbor and its residents for many years to come. We wish him good fishing. 55 Charlotte Harbor NEP 2014 Florida Scientist Acknowledgements The success of the 2014 CHNEP Watershed Summit at bringing together researchers, resource managers, elected officials and citizens from throughout the Charlotte Harbor region to share scientific information would not have been possible without the significant support of our partners and sponsors. Special recognition is given to the esteemed Assistant Guest Editors who professionally and persistently coordinated the technical review of the manu- scripts, including: Mr. Michael Flannery, Dr. Penny Hall, Dr. Phil Stevens, Dr. Cassondra Thomas, and Dr. Dave Tomasko. Technical reviews of the manuscripts in this Special Issue were provided by many scientists who generously shared their expertise and time toward ensuring presentation of sound, well written scientific information.
