Observation Narrative
Resample of 13-year old permanent plot. Corners are now monumented with rebar stakes painted light blue.
The habitat and vegetation of this plot have changed very little since 2001. Floristic composition and total species richness of the two samples are almost identical. The significantly larger basal area of the 2014 resample is due to a slight discrepancy in the boundary that included an additional large Liriodendron tulipifera. Woody species diversity continues to be outstanding and the unusual population of Trientalis borealis noted in 2001 is vigorous and apparently even larger now.
