| Observation Narrative |
Community Type: non-tidal floodplain forest
General Description: Acer rubrun - Nyssa sylvatica dominated floodplain forest located on the N bank of the N Branch of the Rancocas Creek. Floodplain is located in a wide U-shaped bend in the river. Almost all of the vegetation is weedy - the site is a dense tangle of Smilax rotundifolia growing over the shrub layer (dominant species Clethra alnifolia). Floodplain is cut by several seepage channels and low, wide ditches that accumulate excess water. The dikes were dry at the time of the visit. Tree species include some that tend to be more "upland species" such as Quercus alba, Q. velutina, Q. coccinea and Fagus grandifolia. Near the stream edge, the dominant tree species is Nyssa sylvatica. Further back (~20m), the dominant tree is Acer rubrum. Many smallish Lygodium palmatum are found twining through the jungle of Smilax near the stream edge. Soils are sandy and dry verying from very dark brown to very pale yellowish. The only dominant forb in the community is Osmunda cinnomonea, some of which is 4' tall.
General Comments: Lygodium palmatum is also found on the edge of one of the ditches. It will probably be found adjacent to others where there is light penetration.
Community Description: Low diversity floodplain forest community on a high bank on the N shore of the N Brnach of Rancocas Creek. Plot lies about 5' above the level of the creek. Tree strata is dominated by Nyssa sylvatica, shrub strata by Clethra alnifolia and herbaceous layer by Lygodium palmatum. There is <20% herbaceous cover. Smilax rotundifolia covers about 90% of the plot. This section of forest lies in a swale between 2 levels - one next to the creek and another bordering a drainage ditch (dry) about +/- 40 feet to the N end and nearly parallel to the creek. There is no evidence of any recent flooding - no debris, silt or scouring. Any flood debris from previous seasons (several + years ago) could not be seen for the thick tangle of Smilax covering everything. Lygodium palmatum (S3 at the time, as of May 1, 2009, S2) is found twining around the stems and vines seeking light. Soil is sand (blended dark and light) with a layer of sandy loamy muck isolated at ~ 31-39 cm. This layer has a much lower pH than the rest of the soil in the sample. Entire soild profile in acid (4.8-3.8).;
Deerflies present.
