Where theres smoke, theres fire — and, in a recent
case, the smoke also was an indication that some Western Carolina University
students and faculty were taking part in a forestry experiment to determine
if fire can be used as a tool to promote oak regeneration in the Southern
Appalachians.
Three students in WCUs natural resources management program and
Peter Bates, associate professor of natural resources management, joined
with staff from the N.C. Forest Service on April 20 to burn a 20-acre
tract in the Dicks Creek community of Jackson County. Their efforts
are part of a pilot project that may take 10 years to play itself out,
Bates said.
There has been a lot of interest in the use of fire regarding
oak management for a number of years, he said. Investigations
have been conducted by others in many regions of the eastern United
States; however, none of these other studies pertain exactly to the
conditions we have here.
The N.C. Forest Service needs data that will indicate the effectiveness
of using prescribed burns to promote oak regeneration in the mountains,
Bates said. Kerry Lathrop, a Forest Service forester who is a recent
WCU natural resources management graduate, contacted Bates about designing
a study.
The private tract where the April 20 burn took place is owned by a Sylva
physician Tom Wilson, Bates said. The land was selectively logged about
three years ago.
The students and Bates established 53 plots in the 20-acre tract from
which to collect pre-burn data regarding what species, and how many
species, were regenerating after the recent logging operation. Now that
some of the plots have been burned, the project will involve monitoring
the burned and unburned plots to determine how the fire influenced regeneration,
Bates said.
Whether or not the burn promoted oak regeneration is an issue that probably
wont be determined for five to 10 years, Bates said. WCU students
will be monitoring the plots from year to year. If competition from
non-oak species is still too vigorous, the Dicks Creek site may
need to be burned again in the next couple of years, he said.
Bates also said there are plans to extend the project to other counties
in Western North Carolina.
WCU students participating in the Dicks Creek burn were Michael
Forbis of Mt. Croghan, S.C., Michael Harmon of Forest City and Nick
Stowe of Weaverville.
Although oak stands in Western North Carolina are not necessarily in
trouble, there is evidence that their numbers are declining, Bates
said.
There are a number of possible causes, with fire suppression being
one of them, he said. Oak often responds better to fire
than some faster-growing, competing species. It is hypothesized that
fire exclusion allows these other species, such as yellow poplar, black
birch and red maple, to overtop oak, and prevent it from becoming a
major component of future tree stands.
