Layout Narrative |
Transect endpoints are permanently marked with rebar. Distance and compass bearing measurements to the plot location with measurements of plot orientation off the transect were taken. GPS coordinates for corners of the plot were taken with submeter accuracy.; Plot at 10-12m along transect on N side.

Landscape Narrative |
Soil Texture: Organic - muck; Mineral - sandy clay
Depth to Water Table = "at surface";
Abiotic Physical Factors: Iron-rich muck and bog iron fragments indicate possible super-saturation of groundwater. Water quality excellent - may be extremely nutrient poor. Definitely acidic.";
Hydrology influenced by groundwater seepage;
Environmental Comments: "wet panne-like area that backfloods and receives groundwater/surface flow via seepage channel";
Landscape Structure and Extent: "Grades into sedge savanna, seepage channel, and Muhlenbergia savanna, then into cedar swamp.";
Condition of Surrounding Landscape: "Pristine savannah and cedar swamp.";
Hydrologic Influence: Batsto River groundwater (Cohansey-Kirkwood aquifer);
Watershed: Batsto-Mullica
Bare soil is covered with muck and algae; Gravel consists of bog iron.

Observation Narrative |
Community Type: Pine Barrens savanna
General Description: "Pitch pine-oak forest dissected by river corridors with cedar swamps and savannas. Cross-section would contain pitch pine uplands, narrow band of cedar swamp, broad savanna, narrow cedat or Acer swamp on levees, river."; Community Description: "Open, wet panne-like area on seepage channel in savanna dominated by Eleocharis robbinsii, E. olivacea, E. tuberculosa, Utricularia cornuta and Eriocaulon aquaticum. Grades into Muhlenbergia torreyana and Rhynchospora alba dominated sedge savanna."; Evidence of community Processes: "Flooding - seasonal and storm event backflooding, continuous groundwater seepage." EO Size: "Typical for this type - small, limited by location in/adjacent to seepage channel and backwater."; Development/Maturity: "Appears to be held in early succession by continual saturation or inundation and possibly nutrient limitations."; Species Composition and Biological Structure: "19 species, patchy distribution on a sub-meter scale. 4 species of abundance >5%, 14 species sparse cover - fairly rich for such a sparse community."; Ecological Processes: "Seasonal inundation and sporadic flood events in addition to continual groundwater seepage flow. History of fire but no direct evidence."
