  • Ex Situ Conservation
    • taking species from its natural habitat in order to conserve it - may be a wild area or within the care of humans
    • examples
      • Longlete - lions
      • Wales - red kite
      • Marwell
      • Indonesia - Sumatran Rhino (only 200 exist in the wild - half the number of 15 years ago)
      • Bristol Zoo - Vietnamese box turtle
      • Uk, Somerset - rare spoon-billed sandpipers
      • Norfolk - Siberian tigers (only 400 left in the world
    • Positives
      • Social
        • people become more educated and knowledge about the species increases
        • increases public awareness of the importance of preserving biodiversity
        • provide a key role in scientific research
      • Economic
        • can act as a tourist interest - income increase
        • huge income gained - reinvseted for conservation
      • Environmental
        • helps protect species becoming extinct
        • breeding programmes increase numbers
        • have a positive impact on areas whee biodiversity has declined
    • Negatives
      • Social
        • some may not support/be in favour of it - shouldn't be removing animals from their habitat and kept in captivity?
        • unethical
      • Economic
        • Can be expensive - jobs, need the right enviroment
        • require a regular supply of resources and funds
        • may not always prove successful, even after lots of investment
      • Environmental
        • animals may not be able to cope if put back into the wild - lose knowledge of natural habitat
        • m,ay not cope with new environment in captivity etc
        • doesn't do anything to address the underlying issues - destroying their natural habitat!
        • ex-situ = limited gene pool
    • The advantages of ex situ - Breeding
      • Scientists believe there could be just 45,000 wild orangutans left on the whole island of Borneo - a decline of 50% in the last 60 years
      • main threat to orangutan's livse is the destruction of their habitat, the rainforest, by logging companies nd the establishment of oil palm plantations.
      • 3 rehabilitated orangutans have been returned to the wild in Indonesia by the Borneo Orangutan Survival Foundation, from its rescue and reintroduction centre in East Kalimantan
        • after spending most of their lives in human care the 3 orangutans were playing happily in the junge treetops - as nature intended
        • airlifted from the Samboja Lestari Rescue and Reintroduction Centre ni the east of the island of Borneo to the Kehje Sewen forest to the south
      • rare release of one of the world's most endangered primate species was made possible by funding provided by an internation group of fundraising partners
        • including British charity, Orangutan Protection Foundation
