LIST OF FIGURES (CONT.) VOLUME 2 Figure Page Chapter 7 (Cont.) 7.26 Frequency of Occurrence of Parthenocissus quinquefolia, Smilax sp., Toxicodendron radicans and Vitas rotundifolia in (a) Natural Com- munities in Florida and (b) Constructed Forested Wetlands; and (c) Frequency of Occurrence of Other Vines Species in Constructed Forested W etlands................................................................................... 7-90 7.27 Available Soil Nutrient Signatures in Florida's Natural Communities: (a) Xeric Pine, (b) Mesic Hardwood, (c) Flatwoods, (d) Lake Fringe, (e) Marsh, (f) Bayhead, (g) Cypress Dome, and (h) Hardwood Swamp (from Davis and others 1991) ...................................................... 7-92, 7-93 7.28 Available Soil Nutrient Signatures for Constructed Forested Wet- lands......................................................................................7-94, 7-95, 7-96 7.29 The Successional Trajectories of Organic Matter and Bulk Density in Those Sites That Were Identified as Better Than Average Wetlands Using the Understory Community Wetland Status............................... 7-99 7.30 Hypothetical Community Basal Area Trajectories Based on (a) Exponential Regression of Mean Community Basal Area of Research Sites and (b) Exponential Curve Modified to a Logistic Growth Curve. Horizontal Dotted Line Represents the Community Basal Area of a Natural Mixed Hardwood Swamp........ ... ..................................................................... 7-100 7.31 Three Relationships Between Soil Parameters: (a) Soil Moisture vs. Bulk Density, (b) Soil Organic Matter vs. Bulk Density and (c) Soil Water Content vs. Soil Organic Matter. Data Used to Construct the Relation- ships Were from Those Sites Falling Below the Average for Plant Community Wetland Status in Figure 13. The Gray Line Represents the Regression for All Subsamples. Those Samples Falling in the Unshaded Region Above the Gray Line Have Exceeded the Mean for That Relationship ................................................................................. 7-103 7.32 Ninety-Five Percent Confidence Intervals for Relationships Between (a) Soil Water Content and Bulk Density, (b) Soil Organic Matter and Bulk Density, and (c) Soil Water Content and Soil Organic Matter. Gray Lines Represent the Upper and Lower Bounds of a 95% Confidence Interval................................ ............................................ 7-105 7.33 Soil Relationships at LP2 Phase 1, a One-Half-Year Old Constructed Forested Wetland. Gray Line Represents the Composite Value for All Sites. Circles and Black Line Are from LP2 Phase 1 Only.......... 7-106 xxii
