A marshland is a type of wetland, an area of land where
water covers ground for long periods of time.
Unlikeswamps, which are dominated by trees, marshes are
usually treeless and dominated by grasses and
otherherbaceous plants.
Marshlands or wetlands prevent flooding by holding
water much like a sponge. By doing so, wetlands help keep
river levels normal and filter and purify the surface water.
Wetlands are also water reservoir.
Invasive Species are non-native species that causes
ecological and economic problems.

1. The Fire Ants are from the Brazilian rainforest.
They are now causing problems in agriculture,
destroying crops and killing live stocks.
2. The Feral Hogs are from Europe and Asia. It has a
voracious apetite that destroys habitat. The feral hog is
carrier of a virus like the one that cause leptospirosis.
They pose danger to local swines and human beings.
3. Kudzu originated from China and Japan. It was
introduced in the United States to fight erosion. It is
however causing problem because it is spreading so
rapidly. Kudzu overtakes power lines and covers trees
that leads to deforestation.
4. The Flathead catfish originated from the
Mississipi river. The Flathead consumes native
fish in NC rivers. This causes the food chain to
collapse.
5. The insect Hemlock Wooly Adelgid was from
Japan. This insect kills evergreens by laying eggs
and sucking the plant fluids from the needles of
trees.
6. The Nutria was introduced from South
America. This mammal destroys the
marshlands of North Carolina.
1. What are invasive species?
Non-native species that damage the local food chain.
Invasive species cause ecological and economic damage.
2. What are some of the invasive species in North
Carolina?
Fire ants, feral hog, kudzu, Flathead catfish, Hemlock
Wooly Adelgid , and nutria
3. How do fire ants cause economic problems?
Fire ants destroys crops and kill livestocks.
4. How do the Feral hogs cause ecological and economic
problems?
They can transmit diseases to local swines and to human
beings.
5. Why was Kudzu introduced in the United States?
Kudzu was introduced to control erosion.
6. How can Kudzu cause deforestation? Think!
Kudzus covers trees and deprive them of
sunlight.
7. How can the flathead catfish ruin the food chain in
lakes and rivers? Think!
Flathead catfish eats young local fish.
8. How do the insect Hemlock Wooly Adelgid kill
evergreens trees?
They suck plant juices that kills evergreens.
9. Why are North Carolina Marshlands important?
They filter water, act as water reservoir,
habitat for many wildlife.
10. Why is the Nutria ( mammal) considered an invasive
species? Think!
They burrow or dig to much and destroy
marshland plants.
Ecological balance has been defined by
various online dictionaries as "a state of
dynamic equilibrium within a community
of organisms in which genetic, species
and ecosystem diversity remain relatively
stable, subject to gradual changes
through natural succession." and "A
stable balance in the numbers of each
species ... Invasive species destroys the
ecological balance.
