Many insect species have
invaded our forests

The North Carolina Forest
Service monitors invasive forest
pests.
Some invasive species do not come from
across the ocean. They may also come from
other areas of our own lands. New pests can
arrive in North Carolina in a number of ways,
including through infested or infected
nursery plants, wood packaging material, and
even firewood.
Though there are many examples of invasive
forest pests causing damage to trees in North
Carolina, one of most significant pests over
the last century, and one to which most
others are compared, is the Chestnut blight
(Cryphonectria parasitica).

Tiny pests create big problems
 All four native ash species – pumpkin, Carolina, green and white – are susceptible
to attack by the borer. That means an estimated 2.5 million ash trees in the state
are at risk. Damage caused by emerald ash borers may kill trees within three to five
years of initial infestation.
 Adult beetles are metallic green, ½-inch long and 1/8-inch wide, and are active in
North Carolina from late spring through mid-summer. Larvae can be found
underneath the bark throughout the year. The natural flight of the beetles is five to
seven miles per year, but rapid spread has been attributed mostly to the movement
of firewood, Suazo said.

Walnut Twig Beetle
Another pest, the walnut twig beetle, carries the
fungus Geosmithia morbida. This fungus causes
thousand cankers disease, which threatens
North Carolina’s native black walnut trees. After
infestation, a tree dies within two to three years.
Walnut twig beetle was first found in the eastern
U.S. in 2010 and was detected in Haywood
County in fall 2012. Black walnut is valued for its
wood, nuts and ornamental features. It is also
important for wildlife, as its nuts provide food
for birds, squirrels and other small mammals.

Chinese Wisteria: a
beautiful menace
Chinese wisteria is a deciduous, woody twining vine that
climbs up tree trunks to heights of 60 feet or more. It twines
upwards in a clockwise direction. The stems are stout, gray-
brown and covered with fine white hairs
ECOLOGICAL THREAT
The hard woody vines of Chinese wisteria twine tightly
around host tree trunks and branches and cut through the
host tree bark, eventually girdling and killing it. On the
ground, new vines germinating from seed or sprouting from
rootstocks form dense thickets that smother and shade out
native vegetation and impede natural plant community
development. As girdled trees die, canopy gaps are created
which increase the amount of sunlight reaching the forest
floor. While this may temporarily favor some native species, it
also stimulates vigorous growth and spread of wisteria.

Girdled trees
Over time, the wisteria vine grows so large and strong that it squeezes through the
bark of the host tree and cuts off the flow of sap. The tree dies due to lack of
nourishment.

Along the Atlantic intertidal coastline from Maine to North Carolina, this crab is now breeding and increasing rapidly in
number. Because it tolerates a wide range of environmental conditions, it seems all too likely to continue to multiply
and to spread. Because it is not a picky eater, it outcompetes native species such as crabs, fish, and shellfish for food–-
or it eats them, being an opportunistic omnivore that feeds on algae, saltmarsh grass, larval and juvenile fish, and small
invertebrates such as amphipods, gastropods, bivalves, barnacles, and worms. http://eattheinvaders.org/blue-plate-

Lionfish:
killing coral reefs
 www.noaanews.noaa.gov 629x477
A new study looking at how to curb the rapid
growth of lionfish, an invasive species not native
to the Atlantic Ocean, suggests that
approximately 27 percent of mature lionfish will
have to be removed monthly for one year to
reduce its population growth rate to zero.
But the good news is that the invasive fish
happens to be delicious—and NOAA is
encouraging chefs to find new ways to introduce
it to U.S. consumers.
Lionfish are native to the western and central
Pacific Ocean, but have established themselves
from North Carolina to South America. They are
a popular aquarium fish that were likely first
released in Florida waters in the mid-1980s. Since
then, the species has spread rapidly. Scientists
and public officials are seriously concerned at
the effect lionfish are having on reef ecosystems,
since this predator is capable of rapid population
growth and outcompeting native fish for food
and territory.

Coypu (Nutria)
(Myocastor Coypus)
This semi-aquatic rodent is
native to southern South
America, but has been
introduced extensively around
the world for the fur industry
and to control water plants.
Nutria began appearing in fur
farms in Louisiana in the 1930’s.
Since then the population has
expanded throughout the
southeastern United States.

Burmese pythons are sold as pets, but they grow to be very large (up to 200 lbs). A few have killed
household pets and even humans. Some have escaped and others have been set free in the
Everglades. With no natural predators, pythons have become a major threat to all other wildlife there.

Invasive species are plants, animals, or pathogens that are non-native (or alien) to the ecosystem under
consideration and whose introduction causes or is likely to cause harm.
