Community Type: calcareous sinkhole pond
General Description: This sinkhole pond floodplain forest of northwestern New Jersey occurs in solution sinkholes that developed on Allentown Dolomite bedrock with glacial till / bedrock surficial deposits. Soils are shallow silt loam or silty clay loam over bedrock and somewhat poorly drained. The closed-canopy deciduous forest is dominated by Platanus occidentalis, Fraxinus pennsylvanica, and Ulmus americana. Other associates may include Carya alba (= Carya tomentosa), Carya cordiformis, Celtis occidentalis, or Quercus bicolor. The most common shrub is Cornus sericea, with associates including Ilex verticillata and Spiraea alba var. latifolia. Vines include Toxicodendron radicans and Vitis riparia. The herbaceous layer is characterized by Scutellaria lateriflora, Symphyotrichum racemosum (= Aster racemosus), Lysimachia ciliata, Boehmeria cylindrica, and Carex granularis. Associated herbs include Acalypha rhomboidea, Carex bebbii, Carex pellita, Mentha arvensis, Onoclea sensibilis, Dichanthelium acuminatum var. fasciculatum (= Panicum lanuginosum var. tennesseense), and Thelypteris palustris.
Environment: The environmental setting is solution sinkholes that developed on Allentown Dolomite bedrock with glacial till / bedrock surficial deposits. Soils are shallow silt loam or silty clay loam with a pH of 6.6-7.8 and somewhat poorly drained. Terraces and upper slopes are temporarily flooded in late winter and early spring as groundwater enters the ponds through springs and seepage fissures in the bedrock. Passive, low-energy flooding occurs on the upper pondshore and floodplain terrace for an average of 6-8 weeks. Aspect and slope are variable among occurrences, and elevation ranges from 150 to 190 m (495-620 feet). Exposures of bedrock, large rocks, and bare soil are common.
Vegetation: The closed-canopy deciduous forest is dominated by Platanus occidentalis, Fraxinus pennsylvanica, and Ulmus americana. Other associates may include Carya alba (= Carya tomentosa), Carya cordiformis, Celtis occidentalis, or Quercus bicolor. The most common shrub is Cornus sericea, which often forms a dense thicket around the edge of the pond under the overhanging tree canopy. Other shrub associates may include Ilex verticillata and Spiraea alba var. latifolia. Vines include Toxicodendron radicans and Vitis riparia. The herbaceous layer is characterized by Scutellaria lateriflora, Symphyotrichum racemosum (= Aster racemosus), Lysimachia ciliata, Boehmeria cylindrica, and Carex granularis. Associated herbs include Acalypha rhomboidea, Carex bebbii, Carex pellita, Mentha arvensis, Onoclea sensibilis, Dichanthelium acuminatum var. fasciculatum (= Panicum lanuginosum var. tennesseense), and Thelypteris palustris. Large trees are shallow-rooted and windfalls are common.
