This has lead to the development Keys have the largest population at about 49,200. of a variety of interconnected, tropical marine The Middle and Lower Keys have almost the ecosystems. There are both climatic and biotic same population at about 36,000 each. The variations within the Keys that extend over one largest stormwater study area population degree of latitude (~24.5 to 25.5 N) and almost appears to be Key Largo, followed by Marathon. three degrees of longitude (~80.2 to 82.9 W). In 2010, the Upper Keys will still have the largest population at over 52,500, followed by the Lower The designations of Upper, Middle and Lower Keys at about 39,100 and finally the Middle Keys Keys do have some natural constraints that affect at about 28,400. The largest study area the near shore marine and terrestrial populations are Key Largo and Marathon as in environments. The Upper Keys form a fairly 1999. continuous barrier between the coastal waters of the mainland on the west and north sides of the Keys (Florida Bay, Barnes, Blackwater and Card Sounds, and Biscayne Bay; usually called "bayside") and those of Hawk Channel and the Straits of Florida on the east and south of the Keys ("Oceanside"). The Middle Keys have large passes that allow a considerable exchange of water. The Lower Keys have an intermediate tidal exchange from one side to the other. The waters to the north here are more properly considered Southwest Florida Shelf waters rather than part of Florida Bay because they are influenced by Florida Bay and the Gulf of Mexico. Table ES-1 provides a breakdown of the acreage and percentage of land uses based on the existing database provided by Monroe County. About 75 percent of the land is categorized as Forest/Open, Urban/Open or Water/Wetland. The next highest land use is low density The largest population growth for permanent residential (9 percent). The rest of the land uses residents between 1999 and 2010 is projected to account for about 18 percent of the total land in be in Cudjoe Key at 15 percent over the 11 years, Monroe County. followed by Bay Point Key at 12.3 percent and Big Pine Key at 11.3 percent.
