Book Description
Total N showed higher levels in the interior of WCA 1. Results for TC varied with different structures. Higher levels of TP and TCa were found in cattails, an invasive species, while lower levels were found in areas of native plant species. Total N showed little variation within the Water Conservation Area (WCA) overall and no significant correlation with specific vegetation species, but tended to have results that were the contrary to TP and TCa. The lowest mean value for NDVI and NDVI green was found in Open Water and the highest mean value in Hardwood Swamp. NDWI showed a wider range than both NDVI and NDVI green with the lowest mean value found in Sawgrass Marsh and the highest in Open Water, suggesting that spectral data are useful to explain the variability of biophysical signatures within vegetation classes. Functional relationships between spectral indices and TP were analyzed. The TN/TP and TC/TP ratios showed moderate and strong associations, respectively, to different vegetation classes, whereas TC/TN was insensitive. In summary, these findings support the hypothesis that high levels of TP are associated with increased occurrence of invasive plant species and decreased occurrence of native plant species and that nutrient levels vary due to external and internal forcing functions. These results will support the restoration process in the Everglades by increasing the understanding of those factors that cause shifts in vegetative patterns.

Book Description
The Florida Everglades ecosystem is recognised world-wide as a significant wetland whose natural processes have been altered and remain threatened. State and Federal US agencies face critical decisions about the course of conservation and restoration efforts. Synthesising nearly ten years of laboratory and field research of the Duke University Wetland Center, this book provides the long-term integrated scientific studies needed to understand the functioning of this region. Background information about the current and historical ecological conditions of the region set the context for reports of long-term research projects, while a series of gradient studies determine the effects of hydrology and nutrient changes. Subsequent sections present models for predicting responses to various conditions and analyse the studies and models, focusing on management and restoration of the Everglades.

Book Description
PREFACE Within the Florida Everglades, tree islands, which cover only a small percentofthis ecosystem, historically have provided essential habitat for a wide variety ofterrestrial and amphibious plants, birds, and animals. These tree islands, however, have been one ofits least studied features. Because of their less flood tolerant vegetation, tree islands are one ofthe most sensitive components ofthe Everglades to changes in hydrology, and many tree islands have been lost during periods when water levels have been abnormally high or low. Their sensitivity to water level changes makes tree islands potentially one ofthe best and surest measures ofthe overall hydrologic health of the Everglades. Consequently, the maintenance of healthy, functioning tree islands and the restoration ofthose that have been lost will be an important performance measures that will be used tojudge the success ofthe Comprehensive Everglades Restoration Plan (CERP). A symposium, Tree Islands ofthe Everglades, was held on July 14 and 15, 1998 at Florida Atlantic University, Boca Raton, Florida. It was sponsored by Florida Center for Environmental Studies and the South Florida WaterManagement District. This was the first scientific meeting ever devoted to tree islands. The organizers of this symposium were Drs. Arnold van der Valk, Florida Center for Environmental Studies and Iowa State University, Fred Sklar, South Florida Water Management District, and Wiley Kitchens, United States Geological Survey.
