1. In situ Conservation
In situ conservation is the process of
protecting an endangered plant or animal
species in its natural habitat, either by
protecting or cleaning up the habitat itself or
by defending the species from the predators.
Wild life and livestock conservation is mostly
based on in situ conservation.
Eg: biosphere reserves, national parks

10. National Parks
 In 1969 the IUCN declared a national park to be a relatively
large area with the following characteristics.
 One or several ecosystems not materially altered by human
exploitation and occupation, where plant and animal species,
geomorphological sites and habitats are of special scientific,
educational and recreational interest or which contain a
natural landscape of great beauty.
 Visitors are allowed to enter, under special conditions, for
inspirational, educative, cultural, and recreative purposes.

11. Biosphere Reserves
A biosphere reserve is an area proposed by its
residents, ratified by a national committee and
designated by UNESCO’s Man and Biosphere (MBA)
program, which demonstrates innovative approaches
to living and working in harmony with nature.
The term ‘biosphere’ refers to all of the land, water
and atmosphere that supply life on earth.
The word ‘reserve’ means that it is a special area
recognized for balancing conservation with
sustainable use.

12. Ex situ Conservation
Ex situ conservation means literally, “off-site
conservation”.
It is the process of protecting an endangered
species of plant or animal outside its natural
habitat.
While ex situ conservation comprises some of the
oldest and best known conservation methods, it
also involves newer, sometimes controversial
laboratory methods.
Eg: gene banks, zoo

13. Gene Banks
Gene banks are a type of biorespository which
preserve genetic material.
For plants, this could be by freezing cuttings
from the plant or stocking the seeds (eg. In a
seed bank)
For animals, this is the freezing of sperm and
eggs in zoological freezers until further need.

14. Advantage of Ex situ Conservation
• Efficient and reproducible
• Feasible for medium and long term secure
storage
• Wide diversity of each target taxonomy
conserved
• Easy access for characterization, evaluation
and utilization
• Little maintenance
