INVASIVE SPECIES 101

Emerald ash borer.

In natural forested areas there is little
that can be done to control these insects,
but there are several biological control
agents that are being evaluated and
deployed in natural areas. Preemptive
harvesting is an option. However, there
are several chemical options - like stem
injections of emamectin benzoate - to
control these pests on individual, highvalue trees, but this type of chemical
treatment is not feasible in a forest stand.
The gypsy moth (Lymantria dispar) was
accidentally introduced to Boston, MA,
in 1886 by a French man who wanted to
crossbreed it with silkworms (Silkworms
made silk, gypsy moths ate many woody
plant species, so he would have silkproducing caterpillars that weren't picky
eaters.) Once the gypsy moth caterpillars
escaped, they began eating and moving
across the northeastern U.S., into the
Great Lakes region and into the Southeast.
Severe defoliation usually won't kill a
mature tree, but defoliations over successive years can weaken trees and make
them susceptible to other stress factors.
When necessary, aerial applications of B.t.
(Bacillus thuringiensis) can be used to control gypsy moth caterpillars. The USDA
Forest Service has a very robust and successful program to manage gypsy moths
called Slow the Spread, which includes
trapping and chemical applications. There

are several silvicultural strategies to deal
with gypsy moths, including thinning
out preferred species, pre-or post-salvage
harvesting or converting the stand to nonpreferred species.

WHAT CAN WE DO ABOUT
INVASIVE SPECIES?
It seems like we regularly get new invasive species in our forests, and although
it may seem hopeless at times, there
are some things we all can do to help
in the fight against them. While these
pests can move on their own, most of
them are helped along by human activities. For instance, did you know that
insects can live in firewood for up to
three years? For this reason, please don't
move firewood around; get it locally
if you go camping, to deer camp or
wherever you might be (safely!) having a fire. Did you also know that
cogongrass rhizomes or seeds of many
invasive plants can survive weeks or
even months in a clump of dirt on a
skidder? To prevent weed movement,
it's important to make sure contracts
require harvester crews to adequately
clean equipment before moving from
one stand to another. Finally, if you see
something that looks out of place, report
it to your state forestry agency or university extension agent. These agencies

have a lot of great information regarding
invasive species, and they would very
much prefer an attitude of caution over
one of nonchalance. For forest health
issues in the southeastern U.S., visit

has all sorts of information.
Invasive species are here to stay. But
there are ways we can manage them and
still reach our objectives for a given forest stand.
