Conservation Biology

  1. 1. Conservation Biology Ch 5.2
  2. 2. Conservation Biology <ul><li>The study and implementation of methods to PROTECT BIODIVERSITY </li></ul>
  3. 3. Natural Resources <ul><li>“ Parts of the environment that are useful or necessary for living organisms” </li></ul>1) Water 4) Air 2) Sunlight 3) Plant and Animal Resources
  4. 4. Legal Protection of Species <ul><li>U.S. Endangered Species Act of 1973 </li></ul>
  5. 5. U.S. Endangered Species Act <ul><li>It is illegal to harm any species on the endangered or threatened species list </li></ul><ul><li>It is illegal for federal agencies to fund any project that would harm organisms on these lists </li></ul>
  6. 6. Now, we stand a chance!
  7. 7. <ul><li>CITES = Convention on International Trade in Endangered Species </li></ul><ul><li>Established lists of species for which international trade is prohibited or controlled </li></ul><ul><li>This agreement has been signed by more than 120 countries </li></ul>
  8. 8. Preserving Habitats <ul><li>One way to preserve habitats is to make them into national parks </li></ul><ul><li>Ex: Yellowstone National Park, </li></ul><ul><li>Sequoia National Park, </li></ul><ul><li>Big Cypress National Preserve, </li></ul><ul><li>Big Bend National Park </li></ul>Large areas lead to greater biodiversity
  9. 9. Grand Teton Zion Uluru (Australia) Costa Rica National parks
  10. 10. Habitat Corridors <ul><li>habitat corridors : protected strips of land that allow the migration of organisms from wilderness area to another </li></ul>HABITAT CORRIDOR It’s like a special road for organisms to cross
  11. 11. <ul><li>Research shows that corridors can help overcome the effects of habitat destruction and are beneficial for both plants and animals </li></ul>
  12. 12. Working with People Park Ranger Philosophy of sustainable use strives to enable people to use natural resources in ways that will benefit them and maintain the ecosystem
  13. 13. <ul><li>Parks hire _____________ to manage parks and ensure protection </li></ul><ul><li>Some areas of the parks are restricted while other areas allow some access for people to harvest food or obtain materials </li></ul>
  14. 14. Harvesting shade grown coffee Harvesting Brazil nuts SUSTAINABLE USE: These methods can be sustained forever and ever and ever (at least that is what we want to believe) Bamboo forest
  15. 15. Reintroduction and Species Preservation Programs California Condor
  16. 16. Reintroduction and Species Preservation Programs Black Footed Ferret Mexican Gray Wolf Reintroduction programs : release organisms into an area where the species once lived Establishes captive-breeding programs to then release into the wild
  17. 17. Captivity Some species no longer exist in the wild, but a small number of individual organisms is maintained by humans “ any organism that is held by people”
  18. 18. Protecting Plant Species <ul><li>The ideal way to protect a plant species is to allow it to exist in a natural ecosystem. </li></ul>Seeds can be cooled and stored for long periods of time (Because of the seeds, the species can be reintroduced if they were to become extinct) Reintroduction of captive animals is more difficult than for plants In addition, animals kept in captivity may lose necessary behaviors to survive
