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.

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

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

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

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.

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.

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.

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.

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.

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.

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

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

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

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/e. OEl. BMVz. YNw 0: 00 -2: 05
