Vegetation, Peat Elevation and Peat Depth on Two Tree Islands in Water Conservation Area 3-A

摘要: Vegetation (species composition and cover abundance) peat bedrock elevations were sampled along multiple transects across the head, near tail far of two tree islands (designated North Island South Island) in Water Conservation Area 3-A. The heads both are underlain by topographic highs bedrock. layer was thinnest on much thicker tail. thinner suggests that there is a mechanism limits maximum elevation island. Altogether 84 51 species found Island, respectively. results an agglomerative hierarchical cluster analysis indicated 9 7 plant assemblages Although sometimes dominated different species, had ecologically equivalent counterparts Island. Three (dry forest, wet forest-fern) trees shrubs (Chrysolalanus icaco (coco plum), Myrica cerifera (wax myrtle), Salix caroliniana (Carolina willow), Schinus terebinthiflolius (Brazilian-pepper)) primarily islands, which highest elevations, adjacent Sawgrass (Cladium jamaicense) (sparse sawgrass, dense decadent sawgrass-cattail) prairie (Eleocharis cellulosa Torr. Panicum hemitomon Schult.) at lower slough (Bacopa caroliniana, Eleocharis cellulosa, Nymphaea odorata, Utricularia purpurea) lowest elevations. There generally no clear-cut relationship between bedrockor distribution various sawgrass assemblages.
