Public Awareness
Conservation is the protection, preservation,
management, or restoration of wildlife and natural
resources
CONSERVATION OF BIODIVERSITY

14. IN-SITU CONSERVATION:
This is the conservation of genetic
resources through maintenance with in
natural or even man made ecosystems in
which they occur. (On site conservation)
EX-SITU CONSERVATION:
This is conservation outside their
habitats by perpetuating sample
populations in genetic resource centres,
zoos, botanical gardens etc. (off site
conservation)

16. INSITU CONSERVATION
Protected Areas (UNEP-WDPA)
Areas or locations which receive protection
because of their recognized
natural, ecological or cultural values.
209,000 protected areas around the world
(WDPA, 2017)
32.6 million km2 of the land is currently protected
→ 15.4% of the world's terrestrial area & inland
waters
→ 3.4% of the world's oceans

→ 103 National Parks
→ 537 Wild Life Sanctuaries
→ 026 Community Reserves &
→ 067 Conservation Reserves.

activities
Transition zone:
cropping, forestry,
recreation, fishery
etc. activities

22. A Sacred Grove under Kharsu

are the relic forest
segments preserved in
the name of religion and
culture

24. ExSITU CONSERVATION
Gene Banks
Botanical Gardens & Zoos

25. Tissue Culture Banks Long term captive breeding

26. Advantages of ex-situ preservation:
→Endangered animals on the verge of
extinction are successfully breeded.
→ Threatened species are breeded in
captivity and then released in the natural
habitats.
→ It is extremely useful for conducting
research and scientific work on different
species.
