Population estimates for European Colonists were taken from Miller 1998, and ʺNortheast Floridaʺ loosely includes settlers in ʺthe basin of the northward flowing St. Johns River from Lake George to the mouth, as well as the adjacent Atlantic Coast and the intervening coastal plainʺ (Miller 1998). For dates after 1845, ʺNortheast Floridaʺ includes population counts from Clay, Duval, Flagler, Putnam, and St. Johns Counties. Sources: Population counts for the years were provided by Miller Counts from were extracted from Forstall 1995, and counts from the U.S. Census Bureau. Note: U.S. Census data was not available for Flagler County in 1900 and Population estimates for 2010, 2020, and 2030 were extracted from the Demographic Estimating Conference Database, updated August

REGULATORY DEFINITIONS OF WETLANDS The St. Johns River Water Management District (SJRWMD) issues permits pursuant to part IV of Chapter 373, F.S. (the Florida Department of Environmental Regulation delegated authority over wetland permitting to the SJRWMD in 1988). The U.S. Army Corps of Engineers issues permits pursuant to Section 404 of the Clean Water Act, Section 10 of the Rivers and Harbors Act of 1899, or Section 103 of the Marine Protection, Research and Sanctuaries Act. GOVERNMENTAL ENTITY (REFERENCE) U.S. Fish and Wildlife Service (Cowardin et al. 1979) U.S. Army Corps of Engineers (33 CFR 328.3) U.S. Environmental Protection Agency (40 CFR 230.3) U.S. Soil Conservation Service (National Food Security Act Manual 1988) (The Act is commonly known as the ʺSwampbusterʺ) State of Florida (Section (17) of the Florida Statutes, and Section (19) of the Florida Administrative Code) WETLAND DEFINITION ʺWetlands are lands transitional between terrestrial and aquatic systems where the water table is usually at or near the surface or the land is covered by shallow water. For the purposes of this classification wetlands must have one or more of the following three attributes: (1) at least periodically, the land supports predominantly hydrophytes; (2) the substrate is predominantly undrained hydric soil; and (3) the substrate is nonsoil and is saturated with water or covered by shallow water at some time during the growing season of each year.ʺ ʺWetlands are those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas.ʺ ʺWetlands are defined as areas that have a predominance of hydric soils and that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and under normal circumstances do support, a prevalence of hydrophytic vegetation typically adapted for life in saturated soil conditions, except lands in Alaska identified as having high potential for agricultural development and a predominance of permafrost soils.ʺ ʺʹWetlandsʹ... means those areas that are inundated or saturated by surface water or ground water at a frequency and a duration sufficient to support, and [that] under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soils. Soils present in wetlands generally are classified as hydric or alluvial, or possess characteristics that are associated with reducing soil conditions. The prevalent vegetation in wetlands generally consists of facultative or obligate hydrophytic macrophytes that are typically adapted to areas having soil conditions described above. These species, due to morphological, physiological, or reproductive adaptations, have the ability to grow, reproduce or persist in aquatic environments or anaerobic soil conditionsʺ (F.S (17) 1995) 40

Dahl had access to more detailed aerial photos which permitted more precise determination of forested wetlands (Dahl pers. comm., as cited in Meindl 2005). Net increases in total wetlands are attributed to increases in manmade freshwater ponds (Dahl 2005). When Dahl re analyzed the mid 1980 s maps and compared them to mid 1990 s maps, he calculated a net loss of wetlands equal to 52,600 acres (Dahl 2005). St. Petersburg Times reporters compared satellite images dated late 1980's and 2003 and found a loss of 84,000 acres. Pittman, Craig, and Matthew Waite. 2005, May 22.
