7
Invasive insects

• Can also cause drastic changes habitat
• Can endanger animal species. For example certain

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

  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.

• 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

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
