  1. What is biodiversity? • Contracted form of “biological diversity” • Biodiversity: variety of life forms living within an ecosystem

  2. Which picture represents a greater amount of biodiversity? High species diversity Monoculture

  3. Which picture represents a greater amount of biodiversity? Low genetic diversity Higher genetic diversity

  4. Biodiversity • When a habitat is very diverse with a variety of different species, it is much healthier and more stable

  5. D = Douglas Fir

  6. N = Noble Fir

  7. C = Western Red Cedar

  8. M = Vine Maples

  9. H = Western Hemlock

  10. W = White Fir

  11. L = Lodgepole Pine

  12. WWP = Western White Pine

  13. BLM = Big Leaf Maple

  14. WD = Western Dogwood

  15. Summary Questions • What did this simulation demonstrate? • Why didn't all the different trees get the disease in the second scenario? • Why didn't the disease spread as fast among the Douglas firs as it did in the first simulation?

  16. Summary Questions 4. Growing one plant, like in the first simulation, is called a monoculture. Give other examples of monocultures. 5. Why would you need to use insecticides and herbicides in a monoculture? 6. If we wanted to help promote wildlife, what could we do to the school’s landscaping?
