#3 In situ conservation may require active management of nature reserves or national parks. #4 Ex situ conservation is the preservation of species outside their natural habitats.

Categorizing: Indicate the conservation management procedure type

Remove endangered organism from natural habitat

Captive breeding of animals

Endangered species cannot remain safely in natural habitat

Rewetting wetland

Reintroduction of species that have become locally extinct

In situ

Ex situ

Endangered organism remains in habitat to which they are adapted

Plant species grown in botanic gardens.

Removal of alien species in natural habitat

Limited predators & controlling poaching
