  • Conservation Methods - Problems with Captive Breeding and Release
    • Problems with keeping species in captivity
      • Too large to keep and/or have very specific habitats e.g. blue whales
      • Difficult to provide enough food e.g. bats, pandas
      • Expensive
      • Complicated species interactions e.g. butterflies and ants
    • Problems with captive breeding
      • Not enough known about habitat requirement = no breeding in captivity
      • Small gene pools may cause inbreeding
        • Combated using a 'stud book'
      • Interbreeding between different plant species causes hybrids = plants lose unique features
    • Problems with seed banks
      • Viability of the seeds declines with storage time = reduced gene pool
        • Seeds have to be germinated regularly = expensive
      • Hard to store large seeds e.g. coconuts
      • Seeds with high water content cannot be dried
    • Problems with releasing captive-bred animals
      • May not recognise food or poisonous foods
      • Poor hunters or escapees
      • No immunity to local diseases
      • May not be accepted by indiginous population e.g. apes
      • Courtship patterns may be unknown
      • Other species colonised their niche
