-Captive Breeding Programmes
How do Botanic Gardens work?
Grows plants with the best resources e.g. nutrients
How do Seed Banks work?
-Stores seeds for future
-Is an example of a gene bank (store of genetic material)
How does Captive Breeding Programmes work?
-Breeding in human-controlled environment then may be released into the wild
-Not released into the wild due to:
-Diseases
-Some behaviour
needs to be learnt
