1. 10 invasive species
By: Reagan and Amanda

2. Emerald ash borer Origin- Asia
Arrived in New York through shipping crates from Asia
Emerald Ash Borer kill North American ash species including green, white, black, and blue ash.
Impacts on environment/economy- white ash is a very valuable lumber tree. When this species kills the tree off, lumber mills will lose millions of dollars in income.
Methods of control- none

3. Giant Hogweed Origin- Asia
Arrived in New York by being presented to North America as an ornamental garden plant without knowing about the dangers.
Giant Hogweed can severely burn humans skin and leave scarring. It will also stop native plants around it from growing.
Impacts on environment/economy- The giant hogweed will prevent native species to continue growing. It also is a threat to humans health which will cause people to spend a lot of money on medical bills.
Methods of control- herbicide treatments.

4. Gypsy Moth Origin- Europe and Asia
It arrived in North America by Leopold Trouvelot because he thought that he could use the moth species as a base of a silk industry.
The gypsy moth will eat the leaves off of trees and all of the vegetation. They will eat on all trees but they prefer oak species.
Impacts on the environment/economy- eating the leaves off trees and all of the forest vegetation can destroy wildlife habitats, increase the risk of a wildfire, and many other things. It will impact the economy by destroying trees that are valuable.
Methods of control- Pesticides and you can put tanglefoot pest barriers around the tree trunks to stop them from getting to the tree leaves.

5. Asian longhorned beetle
Origin- China and the Korean peninsula
It arrived in North America by crates on ships that have been brought to North America.
The ALB is a major pest to hardwood tree species, they will feed off of them until they kill the tree.
Impacts on the environment/economy- The ALB will cause a major decrease in the number of trees which will cause a major loss of money in the maple and hardwood industry.
Methods of control- Insecticides

6. Sirex woodwasp Origin- Europe, Asia, and North Africa
It arrived in North America from Asia because of trading.
The Sirex Woodwasp effects the pine tree, it will inject a toxic mucus and fungus onto the bark of pine trees while laying eggs.
Impacts on the environment/economy- This insect will destroy the bark of pine trees, which is valuable tree industry.
Methods of control- certain parasitic nematodes kill the wasps larvae.

7. Eurasian Boars Origin- Europe and Asia
It got to North America by European explorers who brought domestic animals with them, then later people started hunting them.
The Eurasian boar competes with native animals for food and it will eat the eggs of ground- nesting birds and reptiles.
Impacts on environment/economy- They impact the environment by wallowing, rooting for food and selective feeding. They impact the economy by causing damage to properties and the properties will have to be repaired.
Methods of control- trapping, shooting, and hunting with dogs

8. Hemlock Woolly adelgid
Origin- Asia
This was brought to North America when Japanese ornamental hemlock trees were brought to the United States from Japan.
The Hemlock Woolly Adelgid mainly impacts hemlock trees and the species that live and use hemlock trees.
Impacts on the environment/economy- It reduces the health of hemlock trees, and hemlocks can be valuable for certain things.
Methods of control- insecticides or foliar sprays

9. Green Crab Origin- Europe and North Africa
It arrived here by shipping in wooden ships.
The green crab is a threat to marine ecosystems because they are vicious predators.
Impacts on the environment/ economy- they impact the environment because they eat a lot of different sea life. They impact the economy by lowering the population of certain sea life so they might have to restock them.
Methods of control- trapping and capturing them

10. Sea walnut Origin- North and South America
It arrived in the United States by the transportation of ballast water.
It impacted the fish population because it was eating all of the zooplankton that the fish eat.
Impacts on the environment/economy- It made the fish population go way down because it was taking all of the fish food. It impacted the economy because the fisherman couldn’t have any fish to sell.
Methods of control-none

11. Killer algae Origin- Indian and Pacific oceans
It got to the united states by being released and it escaped to the Mediterranean sea.
Killer algae will crowd out and replace native algae because it spreads rapidly.
Impacts on the environment/economy- It will take out all of the native algae plants which will take away certain sea animals food which will make the fishing industry net worth go down.
Methods of control- none unless you kill it at an early stage of development.
