Observation Narrative
Taxodium dominated seepage swamp along a tributary of College Run, just above tidal influence. The plot represents the wettest extreme of this community type, which has a composition strongly influenced by soils with extensive shell deposits. Despite very high organic matter content (24%), soil samples collected from this site were extremely calcareous.
