What is an invasive species? A non native species that becomes

established in a new new environment and out competes native species

Does anyone have an example of a invasive species?

Types of invasive species Animals Plants

Pathogens (bacteria)

What is the problem with an invasive species?

Uncontrolled population growthOut compete native organisms for food/space/resources

Endanger the health of other plants and animals.

How do invasive species travel? Humans

Wind Water

Humans- Can simply carry a organism.

Some invasives can stow away on a ship or plane.

Wind- Seeds can be carried great distances.

Water- Organisms can be transported on natural “rafts”

Examples of Invasive Species: Zebra mussel (Dreissena polymorpha) Giant Hogweed (Heracleum mantegazzianum) Asian Tiger Mosquito (Aedes albopictus) Lionfish (Pterois spp.)

Zebra Mussel(2)

Originally from the Caspian and Black Sea.

Introduced to the Great Lakes in 1988. Cause many problems:

Can harm other fresh water mussels Can block intake pipes for power plants Can cause problems for recreational

activities.

Giant Hogweed(2)

Native to Eurasia Introduced to the United States in 1917. Originally used as an ornamental plant It out competes other plants for

resources. It produces a toxic sap.

Asian Tiger Mosquito(2)

Originally from Asia. Introduced to Hawaii in the late

1800’s. Continental United States in 1985.

Can be a vector for disease. Ex. West Nile Virus

Lionfish(2)

Native to the Pacific Ocean Introduced to the water around the

United States in 1992 through the aquarium trade.

Preys on native species. Has poisonous spines.

What can you do?

1. Obey the rules. Do not transport

plants and animals when you travel.

2. Never release pets into the wild.

3. Learn about invasive species in your area for identification.

4. Use native plants.
