| Observation Narrative |
Community Type: non-tidal floodplain forest
General Description: Unusual, dry floodplain forest located on a slightly elevated terrace E of the fresh marsh and W of the adjacent hydric woods. Dominant tree is Ilex opaca which forms a dense canopy layer. Emergent trees are Nyssa sylvatica and Acer rubrum. Mature Ilex trees are well over 100 years old. Beneath the forest is virtually nothing except a thick layer of leaf litter. The few forbs that can survive are Maianthemum canadense and Medeola virginiana. Soil is dry in the top 65cm or so and then becomes damp. Organic matter is found in the upper 40cm of soil horizon and is very acid. There is no evidence in the forest of flood debris except at the lower edge near marsh.
Community Description: Floodplain forest on the E bank of the Cohansey River. Floodplain is bordered by a band of fresh marsh to the E and adjacent to the river, and hydric forest to the W. Forest is dominated by Ilex opaca which forms a dense sub-canopy beneath occassional Acer rubrum and Nyssa sylvatica. There are no shrubs and very few forbs. A thick layer of leaf litter is found beneath the trees. There is little evidence of recent flooding, but tree bases are flared and there are many exposed surface roots. A few piles of debris are found near the marsh edge. Soils are very acid (lower depths off pH kit chart), and organic matter is still found at 85cm. Mineral soil is sandy. Upper layers are dry. Soil becomes damp below 40cm. No evident disturbance. Surrounding communities have invasive species but there is little danger that they will spread to this community.
Evidence of Ecological Processes: Some small piles of flood debris, exposed tree roots.
Woodthrush, white-eyed vireo, greatcrested flycatcher, Fowler's toad, greenfrog, ovenbird, white-tailed deer present.
