Tamassee Creek/Station Creek   Jess

Tamassee Creek flows through the calcareous Brevard Belt a few miles north
of Walhalla, South Carolina. The creek is only a couple of miles north of
the spectacular forests surrounding Tamassee Knob, so I was hoping to see
similar towering hardwoods along the creek. Unfortunately, the forest
service maintains the large flats along the creek as fields of grass with
a narrow corridor of tuliptrees and sweetgums along the creek. Upstream of
the fields the soil is not as rich as that around Tamassee Knob, and the
forest contains a much greater proportion of conifers. The section of this
conifer forest that grows in the gorge like area below a waterfall was cut
only lightly if at all. Both hemlock and tuliptree in this area probably
exceed 200 years in age.
     Where Station Creek encounters the Brevard Belt about four miles south
of Tamassee Creek the stream forms the popular Station Cove Falls. The
forest immediately below the falls has been described as "a remnant of
old-growth forest (140 to 175 years old)" and "one of the best examples of
a mixed mesophytic cove forest in South Carolina" (Gaddy A Naturalist's
Guide to the Southern Blue Ridge Front). I'm not sure where the age
information came from, but the latter description is well deserved. The
forest is dominated by a mix of hardwoods rather than a single species.
Tuliptree, white ash, bitternut hickory, white basswood, american beech,
and northern red oak are all common in the canopy. Yellow buckeye, at the
extreme southeastern edge of its range, is restricted to the mid-story over
american hornbeam and paw paw in the under-story. The diverse herbaceous
ground cover has made the site well know among botanists and the site may
support "more wildflowers and herbaceous plants per square foot" than any
other area in northwestern South Carolina (Gaddy Naturalist's Guide). This
description peeked my interest since I think there is a positive
correlation between herbaceous density and tree height. I did only a
cursory revue of the rich forest below the falls to avoid disturbing the
below there to see the falls and to avoid trampling the wildflowers. I
spent most of my time looking at the drier oak, dominated flat downstream
of the falls. The forest below the falls includes tuliptrees to over 150',
bitternut hickory to over 130', white ash that probably exceed 130', and an
unidentified elm that is likely over 120' tall.

I want to go back and check the heights on some of the Tamassee Creek trees
because the for them are greater than the trees look. I took a second
height on the tallest white oak that was shorter than the first. I have
listed the higher measurement here because shooting vertically on the tree
gave around 139', and that measurement was probably not all the way to the
top twig since the upper crown is narrow. The difference in measurements
may result from obscuring brush causing an artificial shoot distance
reading to the base of the tree. The birch, oak, pine and walnut are all
the tallest I have measured in South Carolina and all exceed the tallest of
their species I have measured in Georgia. The Brevard Belt north of
Walhalla supports some of the finest cove forests in the southern
Appalachians.
