  2. What Does INVASIVE SPECIES Mean? • ALIEN or EXOTIC- Non-Native • Causes problems in the new environment

  3. In the Water Zebra Mussels Asian Carp

  4. Characteristics of Invasive Species: What makes a species invasive? • Reproduce rapidly • Lack predators and diseases that would otherwise keep the numbers down • Adapts to new environments quickly • Plants can change the environment to suit its own survival needs • Able to live off a wide variety of food sources

  5. Are Invasive Species brought here… ON PURPOSE? BY ACCIDENT? OR

  6. European Starling • On purpose or by accident? PURPOSE- In 1890, 100 birds were released into Central Park in New York City by fans of William Shakespeare, who had mentioned the bird in his writings.

  7. European Starling • Where were they originally? EURASIA • Where can they be found now? ALL OVER North America and parts of Canada

  8. Cause and Effect They destroy crops They rob native birds of nesting sites

  9. Purple Loosestrife • On purpose or by accident? BOTH- It was introduced accidentally as a contaminant in the ballast of ships and on purpose as a medicinal herb to treat bleeding, wounds, ulcers, and others

  10. Purple Loosestrife • Where was it originally? EURASIA • Where can it be found in North America now? Mostly in the north, but it has been found in almost every state

  11. Cause and Effect It reproduces rapidly Displaces native plants, eliminating natural food

  12. Emerald Ash Borer • On purpose or by accident? By accident- Thought to be brought to North America in 1990’s in overseas ship containers

  13. Emerald Ash Borer • Where was it originally? ASIA • Where can it be found in North America now? It has been found in 15 states so far and parts of Canada

  14. Cause and Effect Killed at least 50-100 million ash trees One of the most destructive non-native insects in U.S.

  15. What is being done to stop invasive species? • Mechanical- prescribed fire, manual removal, explosives • Biological- natural enemies such as insects or pathogens that attack the invasive species • Chemical- manipulation of water or soil chemistry to increase the growth of native species • Cultural- educating people, encouraging actions that minimize the spread of invasive species

  16. What can YOU do? • NEVER release exotic plants or animals into the wild. • Urge your family and friends to plant only native species in yards or gardens. • DON’T move firewood! • “If you are a boater, inspect and remove aquatic plants, animals, and mud from your boat, motor, and trailer. • Educate your family and friends.
