AN ECOLOGICAL MAP OF FLORIDA'S LAKE WALES RIDGE: A NEW BOUNDARY DELINEATION AND AN ASSESSMENT OF POST-COLUMBIAN HABITAT LOSS

Although the Lake Wales Ridge (LWR) has long been recognized as a distinctive geomorphological and biogeographical feature of peninsular Florida, no precise, documented boundary map exists. We provide an ecological boundary map of the LWR based on soils, topography, vegetation, land use, and species...

520 |a Although the Lake Wales Ridge (LWR) has long been recognized as a distinctive geomorphological and biogeographical feature of peninsular Florida, no precise, documented boundary map exists. We provide an ecological boundary map of the LWR based on soils, topography, vegetation, land use, and species distributions. Our boundary is similar to previous maps, but includes the endemicrich LWR State Forest and the Royce Tract of the LWR Wildlife and Environmental Area, and excludes the "Apopk Knob" lowlands. We also find that there is little support for the delineation of the intraridge valley or the Carlton Ranch Ridge of previous authors. We determined the areal extent of post-Columbian xeric upland habitat loss on the LWR based on soils maps overlain on aerial photographs (1979–1990). Overall, 78% of xeric upland communities on the LWR was lost by 1990; more recent estimates suggest losses of> 85%. Losses were greatest on yellow sands at the northern end of the Ridge, and least on white sands near the southern end. Most LWR edges have been altered by residential and agricultural development. The Lake Wales Ridge, which provides habitat for globally unique and endemic-rich ecosystems, continues to lose wildlands to development. Poster-sized hardcopy and digital versions of the map are available through our website (www.archbold-station.org).
