Few people get to see such an excellent example of a wet longleaf pine savanna listed by botanists and ecologists as one of the most biologically diverse and imperiled ecosystems in North America. The SC Department of Natural Resources' Lynchburg Savanna Heritage Preserve in Lee County is a haven for unusual and rare plants. In the spring, the mating calls of tiny frogs can be almost deafening. What to look for: Along the old logging road that loops across the property, look for insectivorous plants such as the yellow pitcher-plant, hooded pitcher-plant and sundew. A rich array of wildflowers, some common and some quite rare, provides color from spring to fall. Lynchburg Savanna Heritage Preserve has been described as a "hot spot" for a group of sparrow species rarely seen in one place: Bachman's, song, Lincoln's and field sparrows. Cricket frogs are one of the few frog species active during the day. Although you can't help hearing them, you will rarely see them as they move near the water's edge. In drier areas, look for wild turkeys, bobwhite quail and woodcock. When to go: The preserve is open from dawn to dusk, seven days a week. Winter is the best time to observe all four sparrow species, while wildflowers will bloom at various times in all seasons but winter. If you're interested in amphibians, visit during late winter or in the spring.
