Sandhill ecosystems are one of the systems found along the central Florida ridge, Ocala, Lake Wale, and Lakeland ridges. Like all pine communities fire is needed to maintain the system. This habitat occupies the highest points along the ridges and is characterized by having cream to clay colored (yellow) sand. Once the most abundant ecosystem on Florida central ridges, the sandhill community has largely been converted to different uses. Characteristic sandhill trees include longleaf pine, Pinus palustris, broad leaf trees like turkey oak, Quercus laevis, bluejack or upland willow oak, Q. incana. Herbaceous plants include dog banana, Asimina reticulata, florida paintbrush, Carphephorus corymbosum and sky blue lupine, Lupinus diffuses.
