2.2 Land Use Changes in the Alafia River Watershed A series of maps, tables and figures were generated for the Alafia River watershed for three specific years (1972, 1990 and 1999) for purposes of considering land use changes that have occurred over the last several decades. Not all maps and tables are presented in the text that follows, but all can be found in the appendix. The 1972 maps, tables and figures represent land use and land cover generated using the USGS classification system (Anderson et al. 1976). The USGS classification system has a minimum mapping unit of 10 acres for man-made features with a minimum width of 660 feet. The minimum mapping unit for non-urban and natural features is 40 acres for areas with a minimum width of 1320 feet. The 1990 and 1999 maps represent land use and land cover information from the Florida Department of Transportation (FDOT). The FDOT (1999) developed the Florida Land Use, Cover and Forms Classification System (FLUCCS) using the USGS classification system as its basis. Unlike the USGS classification system, the FLUCCS is a hierarchical system with four different levels of classification. Each level contains information of increasing specificity to describe land cover conditions. Minimum mapping units are also smaller. The minimum mapping unit for uplands is 5 acres; for wetlands, the minimum mapping unit is 0.5 acres. The 1990 and 1999 land use/land cover maps prepared for our analyses appear more detailed than the 1972 maps due to the higher resolution of the latter maps and differences in land use categories. As a result, some of the changes in land use between the USGS and FLUCCS derived maps are likely the result of differences in methodologies rather than actual land use changes. However, for presentation and discussion purposes, we combined numerous land use types into fairly broad categories, and thereby eliminated much of the error associated with use of the two classification systems. Land use/cover types identified for our analysis included: Urban; Uplands (including rangeland); Wetlands (forested and nonforested); Mines; Water; Citrus; and Other Agriculture. For purposes of discussion, the Alafia River watershed was divided into several major sub-basins. These sub-basins are: the Alafia Mainbranch, Buckhorn Creek, Bell Creek, Fish Hawk Creek, Lithia Springs, Turkey Creek, North Prong Alafia, and South Prong Alafia. As delineated on land use maps in this report, sub-basins ranged in size from 4,826 acres (Buckhorn Creek; approximately 8 square miles) to 88,303 acres (South Prong Alafia River; approximately 138 square miles). Buckhorn Creek was retained as a separate sub-basin because Buckhorn Springs is the subject of an MFL analysis. As an example of the lumping of sub-basins that was done, the South Prong of the Alafia River is composed of 16 USGS delineated sub-basins most named after a tributary creek (e.g., Gully Branch, Mizelle Creek, etc.). A listing of the smaller sub-basins, which comprise larger sub-basins, is given in Table 2-1. 2-16
