Observation Narrative
Resample of 13-year old permanent plot. Corners are now monumented with rebar stakes painted light blue.
Since 2001, several small Quercus velutina have died, and many stems of Kalmia latifolia have died or lost most of their foliage. The remaining trees have grown very little, and both woody stem density and basal area have remained almost static. Although there is some oak recruitment here, it is outnumbered by that of the fire-intolerant, mesophytic trees Acer rubrum, Nyssa sylvatica, and Fagus grandifolia.
