Threatened & Endangered
species

Definition of endangered species:
Species that are so rare that they are
already in danger of becoming extinct.
These species are very few in numbers
and will become extinct

Definition of threatened species:
Species that are likely to become
endangered species in the near future. These
species are on the verge of becoming extinct
if we do not take steps to protect them.

Table: IUCN Red listed Species in Bangladesh
Spatial & temporal distribution of
threatened & endangered species:
Asian two-horned rhinoceros:
Swamp deer:

The foothills of the Eastern Himalayas in Bhutan and
eastern India.

Lives in the Indian subcontinent's swampy grasslands and
floodplains.

Comilla and the Chittagong Hill Tracts are the two areas
in Bangladesh.

In Bangladesh it can be found in Sundarbans. It is rare Since
1950s.

Black Softshell Turtle:

freshwater turtle found in India (Assam) and
Bangladesh (Chittagong and Sylhet).
Asian Elephant:


Hilly and non-hilly evergreen forests of Chittagong,
Chittagong Hill Tracts (Bandarban, Khagrachari and
Rangamati), Cox's Bazar regions.
The number of wild elephants was projected to be
195-234 in the early 1990s, with 83-100 of them
being trans-boundary elephants.

Assamese Macaque:

Nepal to central Bhutan and the Sundarbans in
Bangladesh, passing through Uttar Pradesh, Sikkim,
Assam, and northernmost West Bengal in northern
India.

Spectacled langur:
Rhesus Macaque:



Chittagong Hill Tracts (CHT) forest .
In 1982,a joint research that there were 1,300 of these
species at the time
Fig: Spectacled langur
It is the only primate species native to the Sundarbans.
They are the most commensal of the non-human
primates in many Asian countries such as Afghanistan,
Pakistan, India, Myanmar, Nepal, China and Vietnam.

Bengal Fox:

Himalayan foothills and the Terai region of Nepal, in
southern India and eastern and southern Pakistan, as
well as in India's east and southeastern Bangladesh
mostly the hilly tropical forests of northern hilly
Chittagong.

Northern Tree Shrew:
Brush-tailed Porcupine:


It is native to Bangladesh, China, India, Lao PDR,
Malaysia, Myanmar, Thailand and Viet Nam.

Occurs mainly in the mixed evergreen forests of the
Chittagong Hill Tracts, but might also occur in the
mixed evergreen forests of Greater Sylhet.
This species has a very extensive natural range in
south-eastern Asia, extending from India and
southwestern China to Malaysia, Borneo, and the
Philippines.

white-toothed shrew:

It is found in Bangladesh, China, India,
Indonesia, Malaysia, Myanmar.

BARI-UNDP team found them in hilly areas of
Chittagong during 2007-2008.

Causes of such extinction:

Habitat destruction.

Invasive Species.

Over-exploitation of Species.

Global Warming and Climate Change.

Pollution.

Human Overpopulation.

Natural Calamities.

Genetic Pollution.

Invasive alien species.
Legal approaches to protect endangered species:

Find out about threatened and endangered species in your
state.

Build a wildlife sanctuary in your backyard.

Using pesticides and herbicides sparingly.

Conserve water in your home and garden.

Stick decals on windows to keep birds away.

Drive slowly to avoid accident with other animals.

Recycle and purchase goods that are environmentally friendly.

Don't litter or otherwise damage fragile habitats that may be home to native/visiting
species.

Lead or engage in a “clean up” campaign of a significant ecosystem in your region.

Never buy endangered species items like ivory, coral, or tortoise shell.

Go to a national wildlife refuge, a park, or any other open area.

Participate in the annual Stop Extinction Challenge with others (and organize).
