3. #1 An indicator species is an organism used to assess a specific environmental condition.
#2 Relative numbers of indicator species can be used to calculate the value of a biotic index.
Activity:
Biotic Index
Stream Index Quality
Stream #1
Stream #2
Stream #3
Stream #4
Stream #5

4. #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

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
