| Popis: | Species composition, cover, diversity, and temporal dynamics of the three main plant communities in the channelized Kissimmee River floodplain were evaluated to provide a baseline for tracking the success of an ongoing restoration project. Much of the drained floodplain supports an upland herbaceous community with cover dominated by the planted pasture grasses Paspalum notatum and Axonopus fissifolius. Mesophytic woody communities are comprised primarily of Myrica cerifera, Baccharis halimifolia, Ludwigia peruviana, and understory ferns, while Sagittaria lancifolia, Pontederia cordata, and Panicum hemitomon are dominant species in remnant wetland communities. Community composition and the associated gradient of weighted averages of wetland indicator species reflect prevailing hydroperiods and land uses on the drained floodplain. Managed hydrologic regimes have promoted temporal stability, with seasonal variability of plant community characteristics limited to a decline in live plant cover and spe... |
