This document discusses biodiversity, endangered species, endemic species, and conservation techniques. It defines biodiversity as the variety of living organisms and ecosystems, and defines endangered species as those near a critical level and increasing each year. Endemic species are those found only in a particular geographical region due to isolation and environmental conditions. Conservation techniques mentioned include proper planning and management of wildlife habitats and populations, establishing sanctuaries and national parks, and legislative trade regulations.

SPECIES

3. BIODIVERSITY
BIODIVERSITY:
Biodiversity refers to
the variety and variability
among all groups of living
organisms and the ecosystem
complexes in which they occur.

4. ENDANGERED SPECIES

5. Endangered Species :
Concept:
The endangered species are those
living organisms which are almost on
the critical level.
Thousands of species of plants and
animals are endangered and the
number increases each year.

7. Effects On Nature
Disruption of food chains and food
webs.
Affects national biodiversity.
Ecological Imbalance

9. Case study for endangered species
• Kokkare Bellure, Karnataka:
Pelican species – They
need to be preserved
because droppings of
these fish eating birds
are rich in nitrates
which is a good fertilizer

11. ENDEMIC SPECIES

12. ENDEMIC SPECIES
Concept :
The concept of Endemism was first
given by CANDOLLE.
When a species is found only in a
particular geographical region because
of its isolation, soil and climatic
conditions, it is said to be endemic.

15. CASE STUDY FOR ENDEMIC
SPECIES
The Indian Desert:
Mangrove Trees –
Mangrove roots
provide support to
unstable soils and
withstand currents
and storms.

17. CONSERVATION TECHNIQUES
The steps for the conservation of the
existing species are:
Proper planning and management should be
made to preserve wildlife in their habitat (in
situ), and in zoos and sanctuaries (ex-situ).
The feeding, breeding and nursing of the
species should be safeguarded.

18. Establishment of sanctuaries and
national parks with optimum living
conditions is necessary.
Proper legislative and administrative
measures should be taken to regulate
international trade of the species.
