2. “Endemic species”:

3.  Endemic species are those species that are found in
just one region and nowhere else in the world.
 Any species whose range is restricted to a limited
geographical area.
 Since endemic species are unique to a particular
geographical region; they are more vulnerable to
extinction
 Isolated geographical areas, such as islands, lakes
or mountain ranges have many endemic species

5.  Show small population size
 Have only one or few populations
 Show little genetic variability
 Usually exploited(over hunted)
 Narrow geographical range
Examples:
 Asian lion
 Kashmir stag
 Purple frog
 Sangai deer
 Nilgiri Tahr

6. Animal
Endemic specie

8.  Endemism is the state of a species being native to
a single defined geographic location, such as an
island, state, nation, country or other defined zone
Types
Paleoendemism :
 Paleoendemism means that a species used to live
in a large area but now lives only in a smaller area
e.g. kiwis
Neoendemism:
 refers to species that have recently arisen, such as
through divergence and reproductive isolation e.g.
lemur

9.  Causes:
 Narrow ecological amplitude
 Geographical barrier
 Changing climate conditions
 Poor adaptability

11.  We should protect them as they are often under the
threat of extinction.
 In total 117 mammal species, 14 species are
endemic
 338 bird species contain12 species that are
endemic
 161 reptile species contain 30 species endemic
 5600 species of vascular plants found in Pakistan
and 400 are endemic.

12.  Know what species are endangered:
 Plant native flora:
 Avoid use of herbicides/pesticides:
 Watch the road and drive carefully:
 Do not buy illegal products come from endangered
species:
 Support zoo and wildlife parks:
 Reduce water consumption:
 Make sure your home is not hazard for wildlife:

13.  Habitat loose
 fragmentation due to draining and filing of inland
wetlands
 Pollution also play an important role in effecting
them
 Overexploitation (excessive use of resource)
 Introduction to new animals and plants

14.  They are more vulnerable to extinction. Since they
are rare, the destruction of their habitats would
reduce their population drastically.
 Endemic species are damaged by various human
activities the distribution rages and population size
of species will be reduced , leaving them vulnerable
to extinction at much higher rate than other
species

18.  The sagebrush, a very common resident of great
BASIN NATIONAL PARK.
 The big sagebrush root system can extended as
much as 90 feet in circumference.
 The plant allows the plant to collect as much as
water as possible during infrequent rain
 And it is an endemic specie.

20. New Zealand
Endemic specie:

26.  Exist only in one geographical region
 Some are endemic to particular continent
 Some are endemic to part of continent
 Others are endemic to single island
 Are Important because restricted to particular
region
 Mostly are endangered so have to save them
 Play important role in environment
