An old road runs along the property line of an old farm that has, for many years, been owned by a hunting club; it's the road that I walked on a pleasant winter morning.
Of the club's 125 acres about one third is comprised of old fields on which the members maintain some small wildlife food plots. The rest of the property is covered with a forest of mixed oak species.
About
20 years ago the club had a timber sale throughout its woodland. That sale was set up and marked by a forester and left
a goodly number of vigorous oaks in the forest, trees that
produced large numbers of acorns in a good seed year. Those acorns fed
white-tailed deer, wild turkeys, black bear and smaller mammals and birds.
Unfortunately,
the timber sale opened the forest canopy, allowing more sun to strike the
forest floor, which promoted invasion by Japanese barberry and its subsequent spread.
As
can be easily discerned from its name, Japanese barberry isn’t native to the
eastern forest. Although wild turkeys, ruffed grouse and some songbirds occasionally
eat the fruit, barberry provides nothing for white-tailed deer. Interestingly, although
an adjacent property has a deer population estimated to occasionally exceed 40 per square
mile, members of the hunting club complain about seeing few deer.
Now,
all those vigorous, acorn producing oaks are marked with small spots of paint.
It appears that the only sources of food for deer in that woodland are destined
to head to the sawmill.
Did
the hunting club desperately need money? Or, were they sold a bill-of-goods by
an unscrupulous forester or logger; told that the trees were “over mature” or “going
back” or that cutting them would produce browse for deer?
In
late fall, winter and early spring white-tailed deer feed primarily on acorns and browse
in the form of twigs of species that they find palatable. Once those
oaks are cut the acorns they produced will also be gone and the barberry will
spread further.
The dense shade cast by thick stands of barberry prevents most tree seedlings from becoming established - there goes any browse the logging might have produced. It
is reported that barberry actually changes the soil’s chemistry and it is well
known that forests with a barberry understory have many more Lyme disease-carrying ticks than healthy forests. Soon the property will look like this - a property with an average of 3,500 barberry plants per acre.
The
hunting club is about to make a big mistake for their land and their sport, a
mistake whose impact will probably last far beyond most of the aging members’
lifetimes.
