The frog trapping data base was supplemented by vocalization surveys, which were conducted weekly between March 1983 and March 1985 and irregularly in March and April 1993. The habitats on the Preserve include high pine sandhills, xeric oak hammocks, mesic hardwood hammocks, sandhill ponds and lakes, swamp forests, and dark water ponds, lakes, and marshes (Franz and Hall 1991). About 15-20% of the Preserve has been severely altered by agriculture. Mesic hardwood hammocks, swamp forests, and darkwater habitats are restricted to the Mill Creek valley. The Mill Creek originates in Lake Melrose (west of the Preserve) and flows across the Preserve in an easterly direction (Fig. 1). This intermittent creek is an upper tributary of the Etoniah-Rice Creek drainage, an important tributary of the lower St. Johns River. Sandhill lakes are generally isolated with respect to one another and to the darkwater flow-through system. There are no flatwoods and permanent streams or springs on the property. The Preserve includes a modest herpetofauna of mostly upland and aquatic species (Appendix 1). The composition of this fauna reflects the Preserve's geographical position on a N-S trending series of sand ridges that lie along the
