Observation Narrative
Plot captures part of a mature mixed hardwood stand occupying the sharp ridge located immediately west of the Great Falls Park visitor parking lots. Scattered trees on this ridge are > 80 cm dbh and a wide range of tree diameters reflects an all-age stand structure. Exotics are minimally represented on this convex spur, and composition is very representative of the Mesic Mixed Hardwood Forest community type. This plot was sampled late in the growing season of 2002 and revisited in April, 2004. The soil sample collected in 2002 had an extraordinarily high Zn value; another sample collected in 2004, had a typical Zn value. Data from the 2004 soil sample were entered into the Virginia Plots Database.
