Q

Conservation

A

Protection of widelife from irreversible damage and decline

2
Q

3 main goals of nature conservation

  1. Maintain essential ecological processes and life support
  2. Preserve genetic diversity
  3. Ensure sustainability utilisation of species and ecosystems
3
Q

Conservation brief history

A

Early awareness for need of regulation with increase population and use of natural resources

First national park = 1872 yellow stone

4
Q

Convention on biological diversity (CBD) and 3 main goals

Signed at rio 92 by 150 government leaders (193 to date). Half the rate of biodiversity loss and improve conservation to those threatened by 2020

  1. Preserve
  2. Sustain use of resources
  3. Equitable distribution of benefits from use of genetic resources
5

Roosevelt 1948 = future generations have a right to receive a world not degraded by us

7
Q

Extrinsic (value of knowing species exist)

8
Q

Nature use values

A

Direct - consumptive (food, fuel) and non-consumptive (athletics, tourism)

Indirect - ecosystem services e.g nutrient and water cycles, oxygen production

Option - use value for this generation

Bequest - use value for future generation

9
Q

A

Ecosystem service considers as free but there is a monetary value being place on nature = anthropocentric argument - appeals to politicians

10
Q

Conserving semi natural ecosystems

A

Most European ecosystems = semi natural = modified by human activity from original state

CBD recognises semi natural ecosystems and the role of human activity in producing biodiversity

Most European semi natural ecosystem = very diverse and often highly valued

11
Q

3 definitions of naturalness

A
  1. Original = state before man became significant
  2. Present = if man had not become a significant factor
  3. Future = if man influence was permanently removed
