Tamassee Knob, SC:
 distractions & surprises

I set out to explore the last cove at Tamassee Knob that I had not seen,
but quickly became so distracted by trees in coves that I had passed
through before that I never reached my destination. A narrow,
north-northeast facing cove contained the greatest concentration. The
back wall of the cove, witch descends at over 35 degrees from slightly
over 1600' to 1300' elevation, produces moister conditions favorable to
white basswood, green ash, northern red oak, tuliptree and black walnut,
as well as a few silverbell in the midstory. 

The next section of cove
descends more gradually, and the ridges on either side rise less than 100'
above the stream. Northern red oaks and other hardwoods occur in the
small flat and slope on one side of the stream while a dense stand of
tuliptrees cloaks the more recently cut opposing slope. Continuing
downstream, black oaks and a mix of hickories dominate a more mature
section of that slope. A large tuliptree stump on the steep slope, the
stand of slightly younger tuliptrees, and a relatively open roadbed
looping through the cove all suggest additional disturbance after the area
was initially cut.

The list below contains trees from multiple coves, but several more tall
red oaks and black oaks could be added to it just form the cove described
above. In one section of that cove, the dominance of black oak and the
frequency of tall individuals surpasses what I have seen the species
attain in any other area. The location of the stand is also somewhat
surprising since most of the rich soils around Tamassee Knob do not stray
that far from steep slopes.

The tall bitternut hickories were reassuring to see since the 154' tree in
Station Cove, a couple of mile to the south, had appeared the lone tall
tree of the species in the area. One other bitternut in the stand of
younger tuliptrees has already reached 130', but has a girth of only
3'9.5". The mockernut hickory was also a present surprise since I had
seen few, and no tall, individuals of the species at the site. Similarly,
the tall pale hickories were unexpected. The individual listed above
exceeds all others from the South Carolina Blue Ridge. 

At first, I
mistook the 137' black oak for a northern red oak. The tree has a more
ascending branch structure and symmetrical crown than the species
typically displays, and should reach 140' within the next few years. The
138' black oak, now the second tallest known in the South Carolina, has a
more open and rounded crown. The table mountain pine is an isolated
individual probably descended from the small stand of table mountain pines
growing in poor soils near the top of the knob. The black walnuts also
rank forth and second in height in the state.
