Hotspots of Biodiversity : (sensitive biodiversity spots)
1) 34 highly sensitive biodiversity spots are reported all over the world.
2) Such areas had once occupied 15.7% area of the Earth.
3) At present, 86% of the sensitive areas are already destroyed.
4) Presently, only 2.3% area of the Earth has been left over with sensitive spots.
5) It includes 1,50,000 plant species which are 50% of the world count.
6) In India, out of 135 species of animals, 85 species are found in the jungles of eastern
region.
7) About 1,500 endemic plant species are found in western ghat.
Endangered Heritage Places :
Endangered Heritage Places of the Country
1) The Western Ghat : The Western Ghat spread over the states of Gujarat,
Maharashtra, Goa, Tamilnadu and Kerala
endangered due to mining industry and search for
natural gas
Habitats of Asiatic lion and wild bison of this region
have been under threat.
2) Manas sanctuary of the endangered due to dams
Assam : Tiger and rhino of that region are under threat.
3) Sunderban sanctuary endangered due to dams, deforestation
of West Bengal : tiger population decreases
Classification of Threatened Species :
1) Endangered Species : Either number of these organisms is declined or
their habitat is shrunk to such an extent that they
can be extinct in near future if conservative
measures are not implemented.
Exampl, Lion tailed monkey, lesser florican.
2) Rare Species : Number of these organisms is considerably declined.
Organisms of these species being endemic may
become extinct very fast.
Example, Red panda, Musk deer.
3) Vulnerable Species : Number of these organisms is extremely less and
continues to decline.
Example, Tiger, Lion.
4) Indeterminate Species : These organisms appear to be endangered but due
to their some behavioural habits
Example, Giant squirrel (Shekhru).
