“…Only the first of these stressors will be ameliorated by CERP and, therefore, the spoonbill 493 assessment tool only addresses issues for water flow, volume and duration. 494 495 Changes in salinity patterns reduces primary production (through stresses caused 496 by rapid and frequent fluctuations in salinity; Montague and Ley, 1993, Ross et al, 2000, 497 Frezza and Lorenz, 2003 and alter the prey base fish community to a state of lower 498 secondary production (Lorenz, 1999, Lorenz andSerafy, 2006). As a result, the overall 499 abundance of spoonbill prey items is reduced.…”

Ecological monitoring is a key part of adaptive management and successful restoration. Not everything within an ecosystem can be monitored so it is important to select indicators that are representative of the system, integrate system responses, show clear responses to system change, can be effectively and efficiently monitored, and are easily communicated. Roseate Spoonbills are one of the indicators that meet these criteria within the Everglades ecosystem. Monitoring of Roseate Spoonbills in Florida Bay over the past 70 years has shown that this species responds to changes in hydrology and corresponding changes in prey abundance and availability. This indicator uses nesting location, nest numbers and nesting success in response to food abundance and availability. In turn, prey abundance is a function of hydrological conditions including depth, and salinity. These relationships have been well documented such that spoonbills responses can be directly related to changes in hydrology and salinity.The spoonbill indicator uses performance measures that have been shown to be both effective and efficient in tracking trends. They are: nesting success, nest number, locations of nests, and prey fish community composition. Targets for these performance measures we established based on previous findings. The performance measures are then reported as suitability indices identified as stoplight colors with green indicating that targets have been met, yellow indicating that conditions are below the target but within a suitable range of it and red indicating the measure is performing poorly in relation to the target.

“…These changes have had many ecological consequences, including alterations in nutrient concentration and distribution, plant community composition, aboveground net primary production, and periphyton dynamics (Newman et al, 1996;Ross et al, 2000;Armentano et al, 2006;Childers et al, 2006;Iwaniec et al, 2006). In an effort to reverse these alterations, significant Everglades restoration activities began in the 1970s (Lodge, 2005), and now fall under the Comprehensive Everglades Restoration Plan (CERP).…”

Although wetlands are among the world's most productive ecosystems, little is known of long-term CO 2 exchange in tropical and subtropical wetlands. The Everglades is a highly managed wetlands complex occupying >6000 km 2 in south Florida. This ecosystem is oligotrophic, but extremely high rates of productivity have been previously reported. To evaluate CO 2 exchange and its response to seasonality (dry vs. wet season) in the Everglades, an eddy covariance tower was established in a short-hydroperiod marl marsh. Rates of net ecosystem exchange and ecosystem respiration were small year-round and declined in the wet season relative to the dry season. Inundation reduced macrophyte CO 2 uptake, substantially limiting gross ecosystem production. While light and air temperature exerted the primary controls on net ecosystem exchange and ecosystem respiration in the dry season, inundation weakened these relationships. The ecosystem shifted from a CO 2 sink in the dry season to a CO 2 source in the wet season; however, the marsh was a small carbon sink on an annual basis. Net ecosystem production, ecosystem respiration, and gross ecosystem production were -49.9, 446.1 and 496.0 g C m -2 year -1 , respectively. Unexpectedly low CO 2 flux rates and annual production distinguish the Everglades from many other wetlands. Nonetheless, impending changes in water management are likely to alter the CO 2 balance of this wetland and may increase the source strength of these extensive short-hydroperiod wetlands.3

“…ENP anglers attached the highest value to improvements in the overall ecosystem health. The case for restoration of freshwater flow in ENP is not just based on improving the fishery habitat Chen and Twilley, 1999;Ross et al, 2000). ENP provides a host of ecosystem services including groundwater recharge, wildlife habitat, carbon sequestration, and mangroves-related services, among others (Richardson et al, 2014;Jerath et al, 2016).…”

• Develops an integrated methodology linking Everglades hydrology to economic values • First ever estimate of anglers' willingness to pay for Everglades recreational experience • Estimates losses in economic welfare due to missing freshwater delivery targets and implicit price of water use for recreation at $41.54 AF -1 • Relevant applications to management, restoration, and climate scenario analysis This research develops an integrated methodology to determine the economic value to anglers of recreational fishery ecosystem services in Everglades National Park that could result from different water management scenarios. The study first used bio-hydrological models to link managed freshwater inflows to indicators of fishery productivity and ecosystem health, then link those models to anglers' willingness-to-pay for various attributes of the recreational fishing experience and monthly fishing effort. This approach allowed us to estimate the foregone economic benefits of failing to meet monthly freshwater delivery targets. The study found that the managed freshwater delivery to the Park had declined substantially over the years and had fallen short of management targets. This shortage in the flow resulted in the decline of biological productivity of recreational fisheries in downstream coastal areas. This decline had in turn contributed to reductions in the overall economic value of recreational ecosystem services enjoyed by anglers. The study estimated the annual value of lost recreational services at $68.81 million. The losses were greater in the months of dry season when the water shortage was higher and the number of anglers fishing also was higher than the levels in wet season. The study also developed conservative estimates of implicit price of water for recreation, which ranged from $11.88 per AF in November to $112.11 per AF in April. The annual average price was $41.54 per AF. Linking anglers' recreational preference directly to a decision variable such as water delivery is a powerful and effective way to make management decision.
