  • In situ and ex situ conservation
    • In situ advantages
      • It allows management of these areas to ensure that ecological integrity is maintained
      • It facilitates scientific research
      • It may be possible to restore the ecological integrity of the area
      • It permanently protects biodiversity and representative examples of ecosystems
      • Plants and animals are conserved in their natural environment
      • It provides opportunities for ecologically sustainable land uses, including traditional outdoor heritage activities and the associated economic benefits
    • In situ disadvantages
      • It takes a long period of time
      • Can be expensive
      • Have to get communities to contribute.
      • Requires a large amount of space
      • Hard to monitor and control - government issues
    • Ex situ disadvantages
      • They are not in their natural habitat and fail to breed successfully
      • Space is limited so it limits the number of individuals, which restricts the genetic diversity
      • A decrease in the genetic diversity of a population results in a lack of variation
      • Can be difficulties with acceptance by the existing wild members of their species
      • If reproduction is successful the animals have to survive reintroduction to the wild, where they need to find food and face predators
    • Ex situ advantages
      • Efficient and reproducible
      • Practical for medium and long term secure storage
      • Wide diversity of each target taxonomy conserved
      • Easy access for characterization, evaluation and utilization
      • Little maintenance
