Layout Narrative	Plot is 2 x 5 m at 74-76 m along W-side of transect. Transect endpoints are permanently marked with rebar. Distance and compass bearing measurements to the plot location with measurements of plot orientation off the transect were taken. GPS coordinates for each corner of the plot was taken with submeter accuracy.

Topographic Position	Basin floor
Landscape Narrative	General Landscape Description: Large sinkhole pond with smaller pond above on ridge divide (connected via surface water at high water levels), with karst terrain on NE-SW oriented dolomite ridges. Surrounding area contains calcareous forest and active farmland. Nearby White Lake exhibits remarkable marl deposits (up to 50 feet deep) around the periphery. The lake occurs in a pre-pleistocene karst valley with a glacial till-dam at the lake outlet on the south side. Piggyback Pond is a solution sinkhole in the karst watershed with dramatic seasonal water level fluctuations. Land use history shows evidence of agriculture, lgging and mining. Soil Texture: Mineral - marl Landscape Setting: Solution valley, collapsed delta plain.

Observation Narrative	Community Type: calcareous sinkhole pond General Description: Upper shoreline of sinkhole pond, rocky, steep, dominated by Boltonia aeteroides asteroides. This particular plot is a monoculture of Cyperus strigosus which covers a large part of the pond. Evidence of Community Processes: Water marks on trees indicated wide fluctuations in water levels (~18'). Other associated species present but not in plot: Xanthium strumarium, Panicum capillare, Mentha arvensis, Bidens cornuta, Bidens frondosa, Boltonia asteroides asteroides. Reconnaissance adjacent to plot: Cyperus strigosus (15%), Panicum capillare (20%), Boltonia asteroides asteroides (5%), Bidens connata (<1%), Bidens frondosa (<1%). Red-tailed hawk and geese are present.
