LIST OF FIGURES (CONT.) VOLUME 2 Figure Page Chapter 7 (Cont.) 7.4 Canopy Cover Analysis (a) Canopy Photograph and (b) High-Contrast Black and White Image After Computer Enhancement. This is an Example of 75% Cover ........................................................................... 7-21 7.5 Frequency Distribution of Tree Diameter at Breast Height from the Chronosequence of Constructed Forested Wetlands. (Size Class Bins: 0-5 cm, 5.1-10 cm, 10.1-15 cm, 15.1-20 cm, 20.1-25 cm...) Sites Appear in Chronological Order ..........................................7-31, 7-32, 7-33 7.6 Diameter at Breast Height Size Class Frequency Distributions by Species .................................................................................... 7-34, 7-35 7.7 Understory Plant Community Status for the Chrono-Sequence of Wetlands Graphed Against Age. Line Represents the Mean Under- story Plant Community Status for All Sites............................................ 7-50 7.8 Number of Plant Species of Each Wetland Status Found in the Understory. One Sampling Quadrat Was Randomly Located in Each 10-Meter Transect Section: (a) FGGSB-2 Transect 1, (b) FGGSB-2 Transect 2, (c) East Lobe Transect 1 and (d) East Lobe Transect 2............... 7-51, 7-52 7.9 The Frequency of Occurrence of Understory Species (< Im in Height) Under Varying Light Transmittance Classes. Those Species Occurring at a Minimum of Ten Sampling Points Throughout the Chronosequence of Wetlands Are Presented. The X-Axis Is in Reverse Order So That Species Occurring Under Low Light Transmittance Levels Occur on the Right ................ 7-53, 7-54, 7-55, 7-56 7.10 On the Left, Available Nutrients on a Mass Basis (mg Nutrient g'1 Soil) and an Areal Basis (g Nutrient m-2 to a Depth of 20 cm, on the Right). Ca (a,b), Mg (c,d), K (e,f), P (g,h) and Fe (i,j) ...................7-60, 7-61, 7-62 7.11 Average KCI Extractable NO3-N, NH4-N and Combined NO3-N and NH4-N at Each Site. In Graphs (a), (c), and (e) Nutrient Values Are Expressed in Milligrams Nutrient Per Gram of Soil. In Graphs (b), (d), and (f), Nutrient Values Are Expressed in Grams of Nutrient per Square M eter to a Depth of 20 cm ..................................................... 7-63 7.12 Three Relationships Among Soil Parameters Are Graphed: (a) Soil Water Content vs. Bulk Density, (b) Soil Organic Matter vs. Bulk Density and (c) Soil Water Content vs. Organic Matter....................... 7-64 7.13 The Relationship Between Soil Water Content and Bulk Density in a Chronosequence of Constructed Forested Wetlands. Sites Are Presented in Chronological Order.......................................7-65, 7-66, 7-67
