Arguments for preserving species

Arguments for preserving species

  • Ethical

  • Aesthetic

  • Genetic Resources

  • Commercial

  • Life Support/ecosystem supportfunctions


Ethical

Ethical

  • Has intrinsic (essential) value

  • Right to exist

  • Human have stewardship over the Earth


Aesthetic visual

Aesthetic (Visual)

  • Recreational

  • Spiritual

  • Educational


Genetic resource

Genetic Resource

  • Diversity of gene pool

  • Ensures future variety of life

  • Needed for stable ecosystems (disease/natural selection)


Commercial

Commercial

  • Food, Medicines, Goods, Resoureces

  • Medicines ($100 billion/year)

  • Ecotourism


Life support

Life Support

  • Flow of material, energy in the biosphere

    • Photosynthesis

    • Pollination

    • Soil formation and

      maintenance

    • Nutrient cycling

    • Moderation of weather

      extremes

    • Purification of air and

      water

UNEP

  • United nations environmental program

  • Provide leadership and partnerships worldwide

Key terms

Key Terms

  • Corridors- Strips of land that link reserves together

  • Ecotone- where two habitats meet near a boundary

  • Edge effect- occurs at ecotones because more species are present from the two habitats (increased resources)


Ecotone marsh mangrove

Ecotone (marsh/mangrove)

Edge Effect: More Species Can Be found here at the ecotone!


Criteria used to design protected areas

Criteria used to Design protected areas

  • Size:

    • How large should area be?

    • One large or many small areas?

    • How many individuals must be protected?

    • Reduce Edge Effect

  • Shape: What is the best shape?

  • Proximity: How close together?

  • Corridors: ReservesJoined or separated?


Wildlife reserves design

Wildlife Reserves Design


Cites

CITES

  • Conservation of International trade in endangered species (CITES)

  • Reduced trade in endangered species

    • Appendix I: cannot be traded threatened with extinction

    • Appendix II: can be traded but with strict regulation

    • Appendix III: Included at request of country to help regulate illegal exploitation
