The Everglades National Park (ENP) is the southern most portion of the Greater Everglades ecosystem. As part of a large scale investigation of the soil biogeochemical properties of the Everglades, 342 sites in the ENP were sampled via soil coring and parameters such as total phosphorus (TP), total nitrogen (TN), total carbon (TC), total calcium (TCa), loss on ignition (LOI), and bulk density (BD) were measured at three depth increments in the soil profile (floc, 0-10 cm, and 10-20 cm). Geostatistical analysis and GIS applications were employed to interpolate spatial distributions of these properties and to investigate linkages between biogeochemical properties of soils across the entire extent of the ENP. Results of these investigations and the ecological significance of these relationships will be presented.
