Species-Based Conservation Strategy for Biodiversity
Class notes (with a little extra!) – Species Conserve
‘In situ’ conservation:
Maintaining species in their natural environment. This may include management of a Nature Reserve or National park. Why is it easier to protect an area if there is a well-known mammal in it?
‘Ex situ’ conservation:
Maintaining species outside their natural environment, in zoos or wildlife sanctuaries. What are the relative strengths and weaknesses of:
- Captive breeding [breeding of species in confinement] and re-introduction programs [back to their original habitat once it is safe to do so] http://nationalzoo.si.edu/SCBI/EndangeredSpecies/CapBreedPops/default.cfm See Mauritius Kestral in hand out too
- Zoos – How are they justified? http://www.waza.org/en/site/home
- What about botanic gardens? Botanic Gardens Conservation International http://www.bgci.org/ Singapore Botanical Gardens [SBG] http://www.sbg.org.sg/
- CITES – Convention for Trade in Endangered Species: controls the transfer of wildlife and wildlife products between member countries (refer to handout for Black Rhino and CITES efforts)
- Which type of species should be more valued for conservation purposes – aesthetic (flagship) or ecological (keystone)? Selecting of “charismatic” species help to protect others in an area (flagship/umbrella species) yet selecting keystone species protect the integrity of the ecosystem structure – i.e. foodweb
