THE 1980S, AFTER A CENTURY OF ABUSE, A DECADE OF PROTECTION AND RESTORATION OF THE EVERGLADES (FLORIDA).
Creator
NICKELS, SARA R., Florida Atlantic University, Curl, Donald W.
Abstract/Description
In the 1980s, confronted by severe problems created by one hundred years of drainage and flood control in Florida, public officials realized a new policy, while continuing to provide flood protection, must protect the environment and wildlife. This involved restoring the natural water flows to wildlife refuges, Everglades National Park, and other wetland areas. New legislation controlling the water supply, water quality, and the wetlands was passed. The Save Our Everglades program proposed to...
Show moreIn the 1980s, confronted by severe problems created by one hundred years of drainage and flood control in Florida, public officials realized a new policy, while continuing to provide flood protection, must protect the environment and wildlife. This involved restoring the natural water flows to wildlife refuges, Everglades National Park, and other wetland areas. New legislation controlling the water supply, water quality, and the wetlands was passed. The Save Our Everglades program proposed to restore the Everglades (the Kissimmee River Basin, Lake Okeechobee and the Everglades) to look and function more as it did in 1900 than in 1983 when the program was initiated. Problems, primarily caused by increasing population and agriculture, continued to thwart restoration efforts.

Determining vegetative complexity, biodiversity and species richness on tree islands of the northern Everglades
Title
Determining vegetative complexity, biodiversity and species richness on tree islands of the northern Everglades.
Creator
Day, Irving M., IV., Florida Atlantic University, Gallagher, Jacqueline
Abstract/Description
Loss of species richness and vegetative biodiversity in the Greater Everglades Area is in large part due to human encroachment and compartmentalization causing altered hydroperiods, water levels and surface sheet flow. This study quantifies vegetative complexity, biodiversity and species richness on four tree islands within a near pristine area of the historical northern Everglades ecosystem. A Complexity Index (CI) was formulated by assessing multiple variables; high CI and low herbaceous...
Show moreLoss of species richness and vegetative biodiversity in the Greater Everglades Area is in large part due to human encroachment and compartmentalization causing altered hydroperiods, water levels and surface sheet flow. This study quantifies vegetative complexity, biodiversity and species richness on four tree islands within a near pristine area of the historical northern Everglades ecosystem. A Complexity Index (CI) was formulated by assessing multiple variables; high CI and low herbaceous species richness values are attributed to mature, late successional stage forests. There are structural and population differences on each of the tree islands studied with the more mature tree islands located in the south of the study area, the more disturbed, low CI valued sites to the north. Data from this study is to be used as a baseline study for the area, and will be used to test and track the effects of the Comprehensive Everglades Restoration Plan.

Non-indigenous fishes in restored and natural wetlands on the Big Cypress Seminole Indian Reservation.
Creator
Dunker, Kristine J., Florida Atlantic University, Volin, John C.
Abstract/Description
This study documented assemblages of native and non-indigenous fishes in restored and natural wetlands within the Big Cypress Swamp. Within the restored wetland, non-indigenous fishes constituted only a minor component of the entire fish community in the restored wetland, although large fish assemblages were dominated by non-indigenous fishes. Among assemblages of species with similar ecologies, nonindigenous species may impact native species in the restored wetland. Within the natural...
Show moreThis study documented assemblages of native and non-indigenous fishes in restored and natural wetlands within the Big Cypress Swamp. Within the restored wetland, non-indigenous fishes constituted only a minor component of the entire fish community in the restored wetland, although large fish assemblages were dominated by non-indigenous fishes. Among assemblages of species with similar ecologies, nonindigenous species may impact native species in the restored wetland. Within the natural wetlands, non-indigenous fishes became more conspicuous during the second year of this study. Hydroperiod and water depth were important factors influencing fish communities in both study habitats. Attempts to block access of non-indigenous fishes from canals into the restored wetland appeared to limit invasions of non-indigenous species, although it did not entirely exclude them. Two new non-indigenous fish species in the Big Cypress Swamp, Hoplosternum littorale and Belonesox belizanus were also documented.

Abstract/Description
This study investigated variations m body condition of brown hoplos (Hoplosternum littorale) refuging in ponds in the Big Cypress region of southern Florida. During the dry season environmental parameters fluctuated, water depth and dissolved oxygen decreased, while temperature and conductivity increased. Standard lengths and wet weights of 675 juvenile brown hoplos were measured from seven populations. Body condition was compared between populations and through time (early vs. late dry...

During the dry season environmental parameters fluctuated, water depth and dissolved oxygen decreased, while temperature and conductivity increased. Standard lengths and wet weights of 675 juvenile brown hoplos were measured from seven populations. Body condition was compared between populations and through time (early vs. late dry season) using length-weight relationship and Fulton's condition factor. The only significant spatia-temporal variations in body condition occurred in the deepest refuges. One population demonstrated an unexpected positive change in body condition, while another (a deep culvert pond) showed negative changes in body condition over time. Smaller fish (≤S65mmSL) found in these deep-water refuges demonstrated the most change in body condition. Almost all populations exhibited isometric growth but the culvert pond population had variable regression slopes (slopes ≠ 3 for both samples).

Abstract/Description
The Big Cypress Swamp and the Everglades of South Florida are inherently oligotrophic ecosystems that in recent decades have been subjected to increasing agricultural nutrient inputs. While extensive research regarding deleterious effects of nutrient impacts has been conducted in the phosphorus-deficient Everglades, there is a lack of research in Big Cypress Swamp. This 12-month field study assessed the responsiveness of Taxodium distichum, Fraxinus caroliniana, and herbaceous vegetation to...
Show moreThe Big Cypress Swamp and the Everglades of South Florida are inherently oligotrophic ecosystems that in recent decades have been subjected to increasing agricultural nutrient inputs. While extensive research regarding deleterious effects of nutrient impacts has been conducted in the phosphorus-deficient Everglades, there is a lack of research in Big Cypress Swamp. This 12-month field study assessed the responsiveness of Taxodium distichum, Fraxinus caroliniana, and herbaceous vegetation to increased nutrient levels in Big Cypress Swamp. Six nutrient treatments (Control, N, P, K, 2K, and PxK) were applied to the soil surrounding these trees. F. caroliniana had higher photosynthetic rates with 2K treatments and higher growth rates with PxK treatments. T. distichum had higher Leaf Area Index in the P and PxK treatment but did not exhibit other responses to treatment. Herbaceous vegetation showed little response to treatments. This study concluded that potassium may be co-limiting in this ecosystem.

Post-fire Succession and Carbon Storage in the Northern Everglades.
Creator
Reger, Lisa Marie, Benscoter, Brian, Florida Atlantic University, Charles E. Schmidt College of Science, Department of Biological Sciences
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.

Show moreThe Loxahatchee Slough is the largest wilderness island refuge existing in Palm Beach County, Florida. Cultural impacts have altered the hydrology of the area. This study provides a database of historical and geographical information regarding the Slough. Aerial photography and satellite imagery from pre- and post-channelization dates are classified according to vegetation ecosystems. GIS analysis is used to compare these diverse data sets. Changes in hydroperiod are examined, using vegetation as an indicator. Results show a general trend toward dryer hydroperiod vegetation land cover. Since 1979, the Army Corps of Engineers has raised water levels back toward pre-channelization levels, in a portion of the study area known as the Historic Region. Results indicate a positive response, with a net increase of longer hydroperiod vegetation in this region since 1979.
