  • Invasive species By: Dyshon Jones Joe McDonald/Animals Animals—Earth Scenes
  • What is an Invasive species?
    • An Invasive species is an organism that is not indigenous or native to its environment.
    • Invasive species can be a plant, animal or insect.
    • Invasive species can be harmful to the environment, other species, and extremely costly to you and me.
  • Worst Invasive Species
    • European Rabbit- Has been responsible for the extinction of over 8 different mammals
    • Zebra Mussel- Has been detrimental to a variety of species in Great lakes region
    • Ship Rats- Have caused the extinction of certain birds, plants and small mammals
    • Feral Pig- have done millions of dollars worth of destruction done to property and farmland
  • Cons…
    • Cons
    • Can be harmful to environment
    • Can be costly
    • Can destroy property
    • Can be harmful to native species
  • Pros
    • Pros
    • Can be used as a form of non chemical pest control
    • May impact an environment positively
  • Invasive insects
    • Can 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.
    Smccan. “ Asian tiger mosquito
  • 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.
    R. Anson Eaglin. “Asian Long horned Beetle”.
  • 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.
  • Types of invasive animals
    • Burmese python
    • Brown tree snakes
    • Zebra mussel
    • Nutria
  • BURMES PYTHON Python molurus bivittatus
    • Originate in southeast Asia
    • Popular among snake handlers and pet owners
    • Are potential threat because of size, no natural predators and have become a problem because of irresponsible owners.
    Tambako the Jaguar, Burmese Python 4
  • 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.
    Michelle Maani, Nutria
  • 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
    Cheryl Moorehead. “Alainthus Altissima
  • 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
  • CONCLUSION
    • Invasive species can be costly to us and our property
    • Can cause disease
    • Can be harmful to other creatures and there habitats
    • Can even extinct entire breeds
    • Sometimes good but overall are never a good thing for anybody
    • Invasive species are an ongoing and increasingly more critical problem that must be recognized.
