| Observation Narrative |
Community Type: calcareous sinkhole pond
General Description: This community occurs in solution sinkholes on Allentown Dolomite with surficial deposits of glacial till/bedrock complex. Very rarely it will also occur on glacial outwash (kettles). Soils are shallow silt loam, silty clay loam, silty clay, or rarely silt marl, overlaying clay or bedrock. It may also occur, very rarely, on marly muck over peat. Small dolomite rocks are often present on the soil surface. The soils are periodically inundated and are categorized as somewhat poorly drained, poorly drained or very poorly drained. This pondshore community is seasonally flooded. The hydroperiod ranges from 4-14 weeks, averaging 8-10 weeks, with seasonal water level fluctuations as great as eighteen (18) feet in elevation. Slope is flat, gentle or moderate. Aspect is flat, north, northwest, northeast, south or southeast. A vegetation gradient often exists within this community type. The upper shore or narrow terrace of a pond may be dominated by Panicum longifolium, Carex pellita and Panicum lanuginosum var. tennesseense with scattered Aster racemosus and Boltonia asteroides var. asteroides. This graminoid and forb mix grades into a wide zone of the typical Boltonia-Aster-Mentha forb-dominated type mid-slope. Downslope it grades into the Panicum capillare - Cyperus strigosus graminoid zone with scattered Boltonia, Aster or Mentha. The zonation and species dominance vary temporally and spatially with changes in groundwater hydrology. This community is most often associated with the Platanus occidentalis – Fraxinus pennsylvanica – Ulmus americana / Cornus sericea floodplain terrace forest community, the Panicum capillare - Cyperus strigosus community and the Chara non-vascular aquatic community.
