Observation Narrative
Plot captures a rather narrow limestone woodland occupying shallow soils along the top and rim of a limestone bluff subtending Cedar Creek. A small sinkhole is located just outside the just outside the southeastern boundary of the plot. Soils are highly calcareous and the vegetation is extremely diverse, despite rather dry habitat conditions. A few exotic weeds are present at low cover, but none has become invasive.
