Dedication This report is dedicated to the memory of two long-time supporters of the Everglades and its restoration, Drs. Karl Havens and William (Will) Graf. Karl was a member of the faculty of the University of Florida and the director of the Florida Sea Grant program. He was a member of the National Academies Committee on Independent Scientific Review of Everglades Restoration Progress (CISRERP), participating in committees in 2014 and 2016. Karl was an internationally recognized scholar on the response of freshwater and coastal ecosystems to human disturbances, including excess nutrients and climate change. He had considerable research interests and experience in Lake Okeechobee and Everglades restoration, which this committee put to good use. Karl was passionate in his personal and professional interests and always generous with this time and energy. Karl was an ardent and talented photographer and a great resource for interesting eateries in South Florida. Will Graf was a Foundation University Professor Emeritus at the University of South Carolina. He served on CISRERP committees from 2004 to 2016, including as chair for the second biennial review (NRC, 2008). He also served on two prior National Academies Everglades committees from 2002 to 2004. Will had a long and distinguished career in geography, focusing on the geomorphology and hydrology of rivers, and the intersection of science and policy for public lands and waters. Will was generous in professional service, and he chaired or served on more than 20 committees of the National Academies, serving continuously on at least one committee (sometimes more) for 30 years. He had many interests, including hiking, kayaking, and traveling, and he delighted in sharing these passions with other committee members by organizing bicycling adventures in Newport Beach and a subgroup trip to Picayune Strand. The committee fondly remembers Willâs train whistle calling committee meetings to order and his relentless enthusiasm for the application of Everglades restoration science. Karl and Will were tremendous colleagues and great friends. They will be missed. Prepublication Copy xi
Preface The Everglades is a wondrous and unique landscape. This vast wetland drains a complex of sawgrass marshes and sloughs, hardwood hammocks, pinelands, and cypress swamps before discharging into its surrounding estuaries, including the St. Lucie Estuary, the Caloosahatchee Estuary, Biscayne Bay, and Florida Bay. The Everglades is also surrounded by ever-increasing urban development. Although there is an inherent tension between the built and natural environment, a fully functioning Everglades is critical to many ecosystem services that benefit the ever-increasing population of South Florida, including drinking water supply; mitigation against sea-level rise and storm surges; and healthy, productive and diverse wildlife and fisheries, among many others. Unfortunately, drainage and development compromised the form and function of the Everglades and continue to impair the quantity and quality of water. Recent observations show that the Everglades are also increasingly challenged by changing climate. Sea-level rise, erratic and extreme weather, and harmful algal blooms are all manifestations of climate change and have focused public attention on the critical need to restore and protect the natural environment of South Florida. Recognizing the consequences of the long-term degradation of the South Florida landscape, in 1999 the federal government partnered with the State of Florida to initiate the Comprehensive Everglades Restoration Plan (CERP) to maintain and improve the ecosystemâs structure and function. In establishing the CERP, Congress also requested that an independent scientific review be conducted on progress toward restoration with biennial reports. The National Academies formed the Committee on Independent Scientific Review of Everglades Restoration Progress (CISRERP) in 2004. This report is the eighth in the series. This report period coincides with a particularly exciting period for the CERP. Twenty years in, the restoration efforts are, at last, seeing the completion and operation of some projects and progress in others. This transition from planning projects to beginning of their operation, integration, and optimization is rewarding for the many people and groups who have worked long and hard on Everglades restoration. This pivot toward project operation represents an opportunity to learn about the first stages of ecosystem response to restoration and to use this information to inform and guide future restoration efforts. The CISRERP is comprised of scientists, social scientists, and engineers with a range of relevant expertise and experience in the environmental sciences, hydrology, wetland and estuarine science, systems engineering, statistics, modeling, project and program administration, law, economics, and public policy. Some committee members have experience in past CISRERP reviews or have relevant research experience working on the Everglades. Other committee members are less familiar with this complex and important system. This span of experience is healthy and brings a range of perspectives to the issues and activities we considered. The full committee met on four occasions in Florida and twice virtually over a 12-month period. We reviewed reports and published literature, heard oral presentations, and had discussions with federal, state. and tribal personnel, academic scientists, representatives of nongovernmental organizations and interest groups, and the public. I am humbled and honored to work with such a distinguished and dedicated group. The CISRERP members are highly accomplished and have worked diligently and effectively as a team to produce this report. I have been impressed with the careful analysis, ideas, time committed, and thoughtful suggestions by committee members in reviewing materials and developing the report. This report represents a consensus of the committee on the restoration progress and challenges anticipated in future restoration not only from the perspective of the most recent 2-year period, but also more broadly since the CERP was initiated 20 years ago. The committee is indebted to many individuals for supplying information and resources that have been critical to our review. In particular, the committeeâs technical liaisonsâGlenn Landers (USACE), Eva Velez (USACE), Nafeeza Hooseinny (SFWMD), and Robert Johnson (Department of the Interior)â Prepublication Copy xiii
Preface greatly facilitated our work by effectively responding to frequent requests for information and providing access to agency resources and expertise. The committee is appreciative of the efforts of numerous people who readily provided valuable insights and knowledge of the Everglades ecosystem and its restoration through presentations, conversations, terrific field trips, and public comments (see Acknowledgments). The committee has been extremely fortunate to work with gifted staff from the National Academies to help us meet our charge. Stephanie Johnson has been stellar as project officer of eight CISRERP committees for the National Academies. The CERP is a remarkably challenging and interesting program entailing a complex biophysical system, many interconnected restoration projects, a number of federal, state, and tribal agencies who work together to accomplish the restoration, and stakeholders who are passionate about the Everglades but at times have conflicting ideas and interests. Stephanieâs intellect, experience, and tenacity have been essential to help the committee navigate through the complexity in order to address the issues facing CERP. Her perseverance and leadership have been critical in the development of this report. We were fortunate to have the services of Brendan McGovern to support the logistical needs of the committee and provide sage advice on local restaurants for memorable and productive dinners after committee meetings and field trips. Unfortunately, Brendan left the National Academies before the committeeâs work was complete. His positive outlook, hard work, and stories have been missed. Fortunately, Brendan was replaced by Eric Edkin. Ericâs technical mastery was invaluable to the committee, particularly when it was necessary to transition to virtual meetings. Without these capable staff, the committee would have difficulty meeting the challenge of this review and report.
