Lecture 9

October 29, 2008

Discussion topics:

Costa Rica, Portland Metro and Oregon biodiversity plans

reserves and cooridors, genetic

green spaces for current wildlife, species

saving critical habitats

Hot Spots

something like:

95% of biodiversity in 10%

90% of biodiversity in 5%

buy for a particular amount

conservation and use vs. preservation (by exclusion)

TNC approach (again in Costa Rica)

 

Major Concepts from Chapter 10 & 11

Chapter 10:

• definition of biodiversity
• general factors that impact biodiversity
• human factors
• species approach vs. ecosystem approach
• forests as an example of managing natural capital
  • economic services vs. ecological services
  • examples of forest management techniques
  • role of disturbance and fire in management
• tropical deforestation
• management of biodiversity using reserves and corridors (Costa Rica case study)
• adaptive management practices
• "hot spots" - pros and cons of conserving
• ecological restoration - different approaches
• describe the eight-step program that has been proposed by E.O. Wilson for protecting global biodiversity

Chapter 11:

• three types of extinction
• common characteristics of endangered species
• basic and secondary causes of extinction
• non-native species
• legal approaches to saving species
• habitat fragmentation
  • reserves and cooridors
  • critical value of fragmentation
