- 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
- Viability of the seeds declines with storage time = reduced gene pool
- 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
