2. What do you think an invasive species in???

4. What is an Invasive species?  An Invasive species is an organism that is not indigenous/ native to its environment.  Invasive species can be a plant, animal or insect.  Invasive species can be harmful to the enviroment and costly.

5. Worst Invasive Species  European Rabbit- Has been responible for the extinction of over 8 different mamals  Zebra Mussel- Has been detremental to a variety of species in Great lakes region  Ship Rats- Has caused the extinction of certain birds, plants and small mammals  Feral Pig- has done millions of dollars worth of destruction done to property and farmland

6. Pros and Cons…  Cons  Can be harmful to environment  Can be costly  Can destroy property  Can be harmful to native species  Pros  Can be used as a form of pest controll

7. Invasive insects  Can also cause drastic changes habitat  Can endanger animal species. For example certain insects eat other insects that could be food for birds or small rodents  Can spread unique geographical diseases

8. Asian Tiger Mosquito  Originates in southern and eastern asia  First seen in 1985 in Houston Texas  Known for aggressive biting (frequent)  Do Not transfer HIV/Aids but do give EEE (eastern equine encephalitis).  EEE tend to affect horses the most and has a 80-90% fatality rate.

9. Asian Longhorn Beetle  Originally from eastern Asia  First noted in New York 1996 and Chicago 1998  Infest large trees such as Maples and horse chestnut trees.  Since there is no natural predator scientist say there could be serious ecological problems.

10. Invasive Animals  Invasive animals are often introduce to an area for the purpose of pest control.  Invasive animals are hard to predict and ultimately become a problem themselves  For example five cats were brought to South Africa for a mouse problem. Five cats turned into 3400 cats and endangered the bird population.

11. Zebra mussel  Originally from the Black Sea and Caspian Sea in Central Asia  Accidentally brought to America  First seen in Great lakes and have been threatening natural inhabitants because of overpopulation.

12. Nutria  Originally from South America  Brought to america to be famed for there furs but many were let go because of failing farmers.  They eat the tall grass and many other nutrients important to the wetlands of Chesapeake Bay. This animal has become a major problem to the food web in the Chesapeake bay.

13. Invasive plants  Usually come From overseas and are usually exotic looking or have unique qualities. Such as Drought intolerance or are extremely fast growing.  They can be dangerous to native plants and search and kill other plants. (example mile-a- minute, purple loosestrife, and kudzu)  They reproduce in high numbers and spread very extensively and well.  100 million dollars spent to control invasive plants.

14. Types of invasive plant  GOOD  Wheat  Tomatoes  Rice  BAD  Lythrum salicaria (purple loosestrife)  Ailanthus altissima (Tree of haven)  Hedera helix (English Ivy)

15. Tree of Haven (Ailanthus altissima )  Grows In abandoned alleys  Known for how quickly trees are formed and size of growth  Can cause sidewalk damage or can even emerge from already cracked sidewalks

16. English Ivy  Cover Most parts of North America  Notoriously known for growing so high that they cover up other plants lower than itself and killing them  Unless maintained they are advised to not be planted

17. Overview  Invasive species can be costly to us and our property  Can cause disease  Can be harmful to other creatures and there habitats  Sometimes good but overall are never a good thing for anybody http://youtu.be/eOElBMVzYNw 0:00-2:05
