Most of my Black Oak trees seem to be in Lot C. Characterized by dark blocky bark all the way up to the top of the trunk, leathery leaves with fuzzy undersides, and frilly capped acorns. There are some trees in the southern section of Lot A that seem more like hybrids with Northern Red Oak, i.e. the acorns seem intermediate between the two species, and the blocky bark gives way to more streaky bark higher up the trunk. My first confirmed Black Oak was this large specimen in the middle of Lot C.
A second, smaller one grows further upslope to the west.
...and a very large one further up the slope, just before the pine grove. This one may actually be a hybrid with a Northern Red Oak - to be determined.
On the north side of the stream on Lot C, I came across a grove of four more Black Oak trees. Their circumferences at chest height were: 4ft 10.5", 4ft 9.5", 5ft 1.5", and 5ft 0.25".
On the ridge in southern Lot B, there is another, much smaller Black Oak - the only one so far to produce any substantial amount of acorns.
In March 2024, I discovered my largest Black Oak by far, with a circumference at chest-height of 7ft 8". It is deep within the rhododendron thicket in the NE section of Lot C. A couple of frilly acorn caps at its base confirmed its identity.
There is another big Black Oak tree upslope to the north from the southern stream in Lot C, circumference 5ft 10.5".
