Everglades Restoration Accelerates Amid Calls for Clearer Success Metrics
Florida’s massive Everglades restoration project has entered a phase of accelerated construction and early ecological gains, according to a new report by the National Academies of Sciences, Engineering and Medicine. While officials celebrate improved water flows and completed infrastructure, scientists caution that critical water quality standards are still unmet and federal staffing shortages could delay long-term success.
Florida’s historic effort to restore the Everglades is moving at an unprecedented pace, yet a new scientific assessment warns that the project’s ultimate success remains uncertain without clearer metrics and sustained federal oversight. The report from the National Academies of Sciences, Engineering and Medicine, published last month, acknowledges that the multi-billion-dollar initiative has benefited from improved collaboration between state and federal governments and record funding levels. However, as the nearly 26-year effort transitions from a phase of planning to active operations, scientists argue that a more precise vision is needed regarding what the restoration can realistically achieve given environmental constraints and changing conditions.
The pace of construction has increased substantially over the past two years, reflecting the high priority placed on key infrastructure projects. Central to this acceleration is a massive reservoir under construction south of Lake Okeechobee, which serves as the centerpiece of Florida Governor Ron DeSantis’s environmental agenda. Seven restoration projects are now complete, including reservoirs located east and west of Lake Okeechobee designed to mitigate harmful water flows that have contributed to severe algae blooms. Another major reservoir in the Everglades Agricultural Area is scheduled for completion in 2029.
Early signs of ecological improvement are already visible across the watershed. In Everglades National Park, dry season flows east of Taylor Slough have improved, although the impact on salinity levels in the fragile Florida Bay remains difficult to discern due to complex environmental factors. In Shark River Slough, water flows have increased, particularly during the dry season. Additionally, vegetation in the Picayune Strand is transitioning from upland characteristics to those typical of wetlands.
Despite these physical changes, the report highlights that scientific analysis of these benefits has been inconsistent, hindering a comprehensive understanding of the restoration’s progress. The U.S. Army Corps of Engineers and the South Florida Water Management District, which oversee the restoration, have responded differently to the findings. The Army Corps stated it is working with state, tribal, and institutional partners to review the report, while the water management district noted its current focus remains on managing flooding caused by a recent rain event in central and southeast Florida.
Beyond scientific monitoring, the National Academies raised urgent concerns regarding the loss of federal staff responsible for enforcing Endangered Species Act protections. The rehydration of the Everglades presents complex challenges for endangered species such as the Cape Sable seaside sparrow, a ground-dwelling bird found in remote areas of Everglades National Park and the Big Cypress National Preserve. During nesting season, water control structures are closed to protect the sparrows, but this inhibition of water flow can flood tree islands critical to the Miccosukee Tribe and various plant and animal species. This issue is exacerbated by sea level rise.
Casey Darling Kniffin, policy director at Friends of the Everglades, emphasized that funding alone is insufficient without the personnel to manage it. "It takes not only funding, but it takes staff to analyze these project reports," Kniffin said. "It takes staff to communicate to organizations like ours so we can provide stakeholder feedback." She warned that despite record financial investment, a lack of federal staff could lead to significant delays in the future of Everglades restoration.
The report underscores that the success of the restoration hinges on meeting strict water quality standards. A new standard, the Water Quality-Based Effluent Limitation (WQBEL), took effect this year to measure nutrient pollution associated with fertilizer use on sugar farms south of Lake Okeechobee. Before the Everglades Agricultural Area reservoir can operate at full capacity, the WQBEL must be met for at least five consecutive years. According to available data through water year 2025, which runs from May 1 to April 30, this standard has not yet been met.
Scientists warned that if existing strategies fail to bring water into compliance, "aggressive and possibly contentious new actions" will likely be necessary. The National Academies had previously raised similar concerns in 2022 and 2024, concluding in 2022 that meeting the WQBEL by 2026 would be a "significant challenge." Steve Davis, chief science officer at the Everglades Foundation, identified two feasible options to address the pollution: further reducing nutrient flows from sugar farms or expanding engineered wetlands known as stormwater treatment areas. Both solutions are described as costly and politically difficult.
"We have to hit the water quality mark," Davis said. "There is no compromise on that."
The report also notes that the definition of restoration success must evolve as the effects of sea level rise, invasive species, and other factors become more apparent. Even after the massive infrastructure effort is complete, the Everglades will remain highly managed. Urban development demands, water supply needs, flood control requirements, and legal obligations will continue to exert pressure on the ecosystem, alongside climate change, peat loss, legacy nutrients, and invasive species. The scientists called for better communication tools to help decision-makers weigh these competing interests.
Kniffin cautioned against altering the definition of success for political convenience. "The caveat to changing any of the restoration definitions would be that we would want to make sure that the science is influencing that process and not the political will and maybe the fatigue around Everglades restoration," she said. "We have to be careful about changing the goal post just to claim victory on the plan without seeing the ecological benefits."
The report arrives at a pivotal moment for Florida politics. Under DeSantis’s leadership, the state has invested billions in the restoration, even as his administration faced widespread condemnation and federal litigation over the Alligator Alcatraz migrant detention facility, which operated in the Everglades for a year before closing this summer. DeSantis’s second term concludes in January, with Republican Byron Donalds elected to succeed him. Donalds has vowed to make the Everglades a priority, continuing the focus established by his predecessor.
Steve Davis expressed cautious optimism about the current trajectory. "We’ve hit our stride in getting projects constructed, to the point where they’re being operated," Davis said. "And also this report points out we’re beginning to see benefits on the ground." He added that while the undertaking is large and challenging, the progress suggests that large-scale infrastructure can achieve its intended goals.
The National Academies has provided biennial reports on the restoration’s progress since 2004, as mandated by Congress. The mammoth restoration, envisioned as a 30- to 40-year effort, involves dozens of landscape-scale projects spanning central and south Florida. These projects aim to revive the watershed that provides drinking water for millions of people. Historical attempts to drain the Everglades made modern Florida possible but led to severe environmental problems, including harmful algae blooms that have sickened residents and killed marine life.
