  1. What are the estimates of global biodiversity? http://www.catalogueoflife.org/info_about_col.php

  2. Why conserve biodiversity? • Benefits to ecosystems • Food webs • Nutrient cycling • Resources • Economic • Genetic Wild plants may have useful characteristics and could be crossed with domestic crops in order to improve them • Food, timber, fuel • Pollination of crop plants • Ethical and aesthetic • Species could go extinct • Areas of natural beauty not available to future generations to enjoy

  3. What are the threats to biodiversity?

  4. Climate Change

  5. Conservation • In situ – conserving an organism in its normal habitat • Ex situ – Conserving organisms outside of their normal habitat

  6. In situ conservation. UK – National Parks http://www.phinda.com/south-africa-safari/

  7. The convention on international trade in endangered species (CITES) • http://www.cites.org/eng/disc/what.shtml • International agreement signed in 1973 • Aims to ensure that the trade in specimens of wildlife does not threaten their survival

  8. http://www.cbd.int/ • Signed by 150 government leaders in 1992 at the Rio Earth Summit • Promotes the conservation of biodiversity and sustainable use of biological resources. • States that partner counties must adopt ex-situ conservation in support of in-situ measures.

  9. Environmental Impact Assessments (EIA) • Part of the CBD • An EIA is a procedure carried out to assess the likely effects of a proposed development on the environment • What would this involve?

  10. Conservation Ex-Situ • Zoos and botanical gardens • Seed Banks • Zoos • Role has changed over time – modern zoos often focus on breeding programs and re-introducing organisms into the wild. • Problems • Often don’t breed • May not survive when re-introduced • Limited genetic diversity • Seed banks • http://www.kew.org/science-conservation/conservation-climate-change/millennium-seed-bank/index.htm

  11. a) What does it mean when an animal is endangered? (1) b) Give two measures might the CITES take to protect this animal? (2) a) What information might be gathered as part of an EIA? (2) b) Why might some environmentalists object to EIAs? (2)

  12. Seed banks • http://www.kew.org/science-conservation/conservation-climate-change/millennium-seed-bank/index.htm • What is a seed bank? • How are the seeds stored? • http://www.kew.org/science-conservation/save-seed-prosper/millennium-seed-bank/saving-seeds-worldwide/saving-seeds-at-the-seed-bank/seeds-in-cold-storage/index.htm • How can you check that the seeds are still viable? • What might be the animal equivalent of a seed bank?
