- Abstract/Description
-
To improve water quality as part of a large restoration effort, constructed herbaceous wetlands will be used as filters of high nutrient water. In this study, I tested whether mixed forested wetlands could also be used as nutrient filters. I examined water quality parameters within a forested slough isolated from direct anthropogenic disturbance and within an impounded forest wetland receiving direct agricultural effluent. Among the water quality parameters, TP and K concentrations in the...
Show moreTo improve water quality as part of a large restoration effort, constructed herbaceous wetlands will be used as filters of high nutrient water. In this study, I tested whether mixed forested wetlands could also be used as nutrient filters. I examined water quality parameters within a forested slough isolated from direct anthropogenic disturbance and within an impounded forest wetland receiving direct agricultural effluent. Among the water quality parameters, TP and K concentrations in the forested slough were particular low. Although all nutrients, except TKN, were higher in the impounded wetland, nutrient concentrations within the wetland were lower at interior sites as compared to inflow water. Based on the use of chloride as a conservative tracer, this reduction resulted predominantly from biological and chemical processes, while physical processes played a minimal role. This study established that mixed forested wetlands can significantly reduce high nutrient levels in surface water.

- Civic environmentalism: A model for Everglades restoration and a sustainable South Florida.

- Abstract/Description

The Everglades restoration is now the centerpiece for environmental policymaking in South Florida. The 1991 settlement of the Everglades lawsuit marked a new era of environmental politics known as civic environmentalism. Concepts of civic environmentalism are used in this study to determine if policies developed since the 1991 lawsuit settlement support a successful Everglades restoration and a sustainable South Florida, a vital connection that ensures the socio-economic health of the built...
Show moreThe Everglades restoration is now the centerpiece for environmental policymaking in South Florida. The 1991 settlement of the Everglades lawsuit marked a new era of environmental politics known as civic environmentalism. Concepts of civic environmentalism are used in this study to determine if policies developed since the 1991 lawsuit settlement support a successful Everglades restoration and a sustainable South Florida, a vital connection that ensures the socio-economic health of the built environment as well as the environmental health of South Florida's unique ecosystems. Indicators reveal that legislation supports a democratic process, but a nonformal model of civic environmentalism demonstrates that there are weaknesses in many areas, especially on the local level. Results of the study suggest that even though civic environmentalism prevails in some cases, stronger policies that connect both the built and natural environment will be necessary to ensure a successful Everglades restoration and a sustainable South Florida.

- Post-fire Succession and Carbon Storage in the Northern Everglades.

- Abstract/Description
-
Fire plays a key role in the ecology of the Everglades and is a ubiquitous tool for managing the structure, function, and ecosystem services of the Greater Everglades watershed. Decades of hydrologic modifications have led to the alteration of plant community composition and fire regime in much of the Everglades. To create a better understanding of post-fire recovery in sawgrass (Cladium jamaicense) communities, sawgrass marshes in the northern Everglades were studied along a chronosequence...
Show moreFire plays a key role in the ecology of the Everglades and is a ubiquitous tool for managing the structure, function, and ecosystem services of the Greater Everglades watershed. Decades of hydrologic modifications have led to the alteration of plant community composition and fire regime in much of the Everglades. To create a better understanding of post-fire recovery in sawgrass (Cladium jamaicense) communities, sawgrass marshes in the northern Everglades were studied along a chronosequence of time since fire and along a nutrient gradient. Areas closer to a water nutrient source and with fewer mean days dry contained greater total and dead aboveground graminoid biomass whereas live graminoid biomass was greater in areas with less time since fire and with fewer days dry. Post-fire characteristics of sawgrass marshes can provide insight on the effectiveness of fire management practices in the maintenance and restoration of quality habitat in the northern Everglades.

- Development, evaluation, and application of spatio-temporal wading bird foraging models to guide everglades restoration.

In south Florida, the Greater Everglades ecosystem supports sixteen species of wading birds. Wading birds serve as important indicator species because they are highly mobile, demonstrate flexible habitat selection, and respond quickly to changes in habitat quality. Models that establish habitat relationships from distribution patterns of wading birds can be used to predict changes in habitat quality that may result from restoration and climate change. I developed spatio-temporal species...
Show moreIn south Florida, the Greater Everglades ecosystem supports sixteen species of wading birds. Wading birds serve as important indicator species because they are highly mobile, demonstrate flexible habitat selection, and respond quickly to changes in habitat quality. Models that establish habitat relationships from distribution patterns of wading birds can be used to predict changes in habitat quality that may result from restoration and climate change. I developed spatio-temporal species distribution models for the Great Egret, White Ibis, and Wood Stork over a decadal gradient of environmental conditions to identify factors that link habitat availability to habitat use (i.e., habitat selection), habitat use to species abundance, and species abundance (over multiple scales) to nesting effort and success. Hydrological variables (depth, recession rate, days since drydown, reversal, and hydroperiod) over multiple temporal scales and with existing links to wading bird responses were used as proxies for landscape processes that influence prey availability (i.e., resources). In temporal foraging conditions (TFC) models, species demonstrated conditional preferences for resources based on resource levels at differing temporal scales. Wading bird abundance was highest when prey production from optimal periods of wetland inundation was concentrated in shallow depths. Similar responses were observed in spatial foraging conditions (SFC) models predicting spatial occurrence over time, accounting for spatial autocorrelation. The TFC index represents conditions within suitable depths that change daily and reflects patch quality, whereas the SFC index spatially represents suitability of all cells and reflects daily landscape patch abundance. I linked these indices to responses at the nest initiation and nest provisioning breeding phases from 1993-2013. The timing of increases and overall magnitude of resource pulses predicted by the TFC in March and April were strongly linked to breeding responses by all species. Great Egret nesting effort and success were higher with increases in conspecific attraction (i.e., clustering). Wood Stork nesting effort was closely related to timing of concurrently high levels of patch quality (regional scale) and abundance (400-m scale), indicating the importance of a multi-scaled approach. The models helped identify positive and negative changes to multi-annual resource pulses from hydrological restoration and climate change scenarios, respectively.
