Observation Narrative
The plot is representative of dry oak / heath forest undergoing active invasion by white pine. This type of vegetation is extensive on the lower, shaley, acidic slopes of the Elliott Knob - Crawford Mountain area. This sample is characteristic of the typical condition, which has oaks dominating the overstory (with scattered white pine present), poor oak recruitment, and white pine dominating the understory.
