Analysis of Kissimmee River floodplain seed dispersal for vegetation community restoration
Title
Analysis of Kissimmee River floodplain seed dispersal for vegetation community restoration.
Creator
Mezza, Garren., Charles E. Schmidt College of Science, Center for Environmental Studies
Abstract/Description
This research examined the influence of hydrochory (seed dispersal via water), anemochory (seed dispersal via wind), and zoochory (seed dispersal by animals) on the re-establishment of the important floodplain vegetation communities of the Kissimmee River floodplain. Fifty-eight seed species were identified from 19,849 and 43, 894 seeds trapped in hydrochory traps in sites north and south of Oak Creek, respectively. Seeds trapped by anemochory were measurable but were found to be far less...

Fifty-eight seed species were identified from 19,849 and 43, 894 seeds trapped in hydrochory traps in sites north and south of Oak Creek, respectively. Seeds trapped by anemochory were measurable but were found to be far less important than hydrochory, while results showed no evidence of zoochory .... A number of interafting factors, e.g. hydrology, lack of remnants, seed phenology, etc. are limiting the dispersal of broadleaf marsh species north of Oak Creek, delaying range, expansion, and further community restoration.

Spatio-temporal modeling of seed dispersal and aquatic plant community restoration in the Kissimmee River floodplain
Title
Spatio-temporal modeling of seed dispersal and aquatic plant community restoration in the Kissimmee River floodplain.
Creator
Kennard, Stevee., Charles E. Schmidt College of Science, Department of Geosciences
Abstract/Description
This study created an ecological spatial model, using a geographic information system, to visualize the influence of hydrochory on restoration of the three dominant wetland communities of broadleaf marsh, wetland shrub, and wet prairie across the floodplain of the Kissimmee River. Primary parameters incorporated into the model included floodplain hydrology, seed characteristics of buoyancy and dispersal rates, and species flood tolerance. S²rensen's similarity index, comparing spatial...
Show moreThis study created an ecological spatial model, using a geographic information system, to visualize the influence of hydrochory on restoration of the three dominant wetland communities of broadleaf marsh, wetland shrub, and wet prairie across the floodplain of the Kissimmee River. Primary parameters incorporated into the model included floodplain hydrology, seed characteristics of buoyancy and dispersal rates, and species flood tolerance. S²rensen's similarity index, comparing spatial agreement among model output and observed community data, resulted in values of BLM-BB = 0.10, BLM = 0.07, WS = 0.21, and WP = 0.36. The significant discrepancies between modeled and observed community spatial coverage indicated a need for incorporation of more stochastic variables of climatic disturbances, nutrient availability, and soil characteristics. More research on species flood tolerance across smaller spatial scales is also needed, and base data incorporated into the model should also be reliable and consistent if accuracy is to be achieved.

Floodplain habitat use and movements of two centrarchids within pool B of the Kissimmee River, Florida

Floodplain habitat use and movements of two centrarchids within pool B of the Kissimmee River, Florida.

Abstract/Description
Floodplains are important elements of river-floodplain systems. Numerous riverine fishes utilize floodplain habitats for reproduction, feeding, and protection. Largemouth bass and bluegill sunfish were tracked using radiotelemetry, and environmental parameters were measured at fish locations. Bass and bluegill used habitats with the same physical and chemical characteristics. Floodplain habitats were utilized frequently, as much as main river channel habitats. Fishes used habitats dominated...
Show moreFloodplains are important elements of river-floodplain systems. Numerous riverine fishes utilize floodplain habitats for reproduction, feeding, and protection. Largemouth bass and bluegill sunfish were tracked using radiotelemetry, and environmental parameters were measured at fish locations. Bass and bluegill used habitats with the same physical and chemical characteristics. Floodplain habitats were utilized frequently, as much as main river channel habitats. Fishes used habitats dominated by vegetation, with sand substrates, and that were more stable with regard to environmental conditions. Largemouth bass were more mobile than bluegill sunfish. Fish movements may have been in response to unfavorable environmental conditions, as more mobile fishes were associated with higher water temperatures and lower concentrations of dissolved oxygen.

Plant colonization on a newly restored floodplain of the Kissimmee River, Florida
Title
Plant colonization on a newly restored floodplain of the Kissimmee River, Florida.
Creator
Pinneo, Janet R., Florida Atlantic University, Gallagher, Jacqueline
Abstract/Description
This study focused on whether wetland vegetation could become re-established on a newly restored floodplain of the Kissimmee River if seasonal floodplain inundation were re-established. The wetland was re-created by back-filling a section of the Kissimmee Canal and diverting water flow into remnant river meanders. Seasonal flooding did occur during the study period. There were no other interventions to promote wetland plant growth. Ten vegetation quadrats were stratified between the back...

The wetland was re-created by back-filling a section of the Kissimmee Canal and diverting water flow into remnant river meanders. Seasonal flooding did occur during the study period. There were no other interventions to promote wetland plant growth. Ten vegetation quadrats were stratified between the back-filled canal and adjacent floodplain. These quadrats were monitored for 11 months. Of the 68 plant species recorded, 72% were obligate, facultative wetland or aquatic species. Diversity, richness, and percent cover of wetland plants increased with time. Coverage of broadleaf marsh habitat increased with increasing water depths. Vegetation at the end of the study period was similar to pre-channelized estimates. Restoration of hydrologic fluctuations appears sufficient to re-establish wetland habitat in this area of the Kissimmee River basin.
