| Observation Narrative |
Community Type: calcareous sinkhole pond
General Description: This maple - green ash swamp occurs in northern New Jersey and ranges north to the Champlain Valley of Vermont. In New Jersey, it occupies the lowest portion of calcareous sinkhole ponds and is characterized by deep organic deposits overlying marl or carbonate bedrock. This vegetation may also occur more widely in the northeast in areas underlain by calcareous bedrock. The tree canopy is fully closed to partially open and characterized by Acer saccharinum, Acer rubrum, Acer X freemanii (a hybrid of Acer saccharinum and Acer rubrum), and Fraxinus pennsylvanica. Other canopy associates may include Fraxinus nigra, Quercus bicolor, Ulmus Americana. The shrub layer is characterized by Ilex verticillata, Vaccinium corymbosum, and Cornus sericea. The herbaceous layer is characterized by Onoclea sensibilis, Carex crinita, Boehmeria cylindrica, Carex retrorsa, Carex lupulina, Lycopus americanus, Lycopus uniflorus, Thelypteris palustris, Solanum dulcamara, and others.
Other associated species present but not in plot: Mimulus, Microstegia, Onoclea, Scutellaria, Lobelia cardinalis.
NoteS: Beaver-downed trees, windfalls and deer bedding were observed. On 6/1/1998 found Carex cryptolepsis (several clumps - 5 each with 15-20 in flower).
