Endangered speciesAn endangered species is a population of organisms

which is at risk of becoming extinct because it is either few

innumbers, or threatened by changing environmental or

predation parameters. The International Union for

Conservation of Nature (IUCN) has calculated the

percentage of endangered species as 40 percent of all

organisms based on the sample of species that have beenevaluated through 2006. Many nations have laws offering

protection to conservation reliant species: for example,

forbidding hunting, restricting land development or creating

preserves.Only a few of the many species at risk of extinction actually

make it to the lists and obtain legal protection like Pandas.

Many more species become extinct, or potentially will

become extinct, without gaining public notice.

Himalayan Wolf

The terms Himalayan wolfand Canis himalayensis have been

suggested by several Indian biologists for recognition as a critically

endangered canid species, distinct from Canis lupus. In its

morphological features, social and reproductive behavior, the

Himalayan wolf resembles the Tibetan wolf, Canis lupus chanco.

However, the IUCN Wolf Specialist Group has not taken a position

regarding this issue. The editors ofMammal Species of the

World consider the small population to be Tibetan wolves a subspecies

of the gray wolf.

Distribution

Kalpa, Himachal Pradesh

The Himalayan wolf may represent an ancient isolated line of wolves

consisting of a small population of about 350 animals. They inhabit an

area of 70,000 km 2 in the trans-Himalayan region ofHimachal

Pradesh, Jammu and Kashmirinnorthern India, and are adapted to

the cold environment.

Indian VultureThe Indian Vulture (Gyps indicus) is an Old World vulture and is

closely related to the Griffon Vulture, G. fulvus. It breeds mainly on

crags in the hills of Sind in Pakistan, central and peninsularIndia.The birds in the northern part of its range once considered

a subspecies are now considered a separate species, the Slender-

billed Vulture Gyps tenuirostris. These were lumped together under

the name Long-billed Vulture.

The species breeds mainly on cliffs, but is known to use trees to nestin Rajasthan. Like othervultures it is a scavenger, feeding mostly

from carcasses of dead animals which it finds by soaring over

savannah and around human habitation. They often move in flocks.

broad wings and short tail feathers. It is smaller and less heavily-builtthan the EurasianGriffon, usually weighing between5.5 and 6.3 kg

(1213.9 lbs) and measuring 80100 cm (3240 in) long and 205 to

Namdapha flying squirrelThe Namdapha Flying Squirrel (Biswamoyopterus biswasi), the sole

species placed in the genus Biswamoyopterus, is

an arboreal, nocturnal flying squirrel endemic to India, and is listed as acritically endangered species due to habitat loss. First collected

in Deban (on 27 April 1981), no population estimates are available forB.

biswasi, but the known habitat is tall Mesua ferrea jungles, often on hill

slopes in the catchments area ofNoa Dihing river(particularly on the

western slope ofPatkoi range) in North eastern India .The NamdaphaFlying Squirrel, also known as the Biswamoyopterus Biswasi, is

becoming extinct because it is losing its habitat and is prey for other

animals. The Namdapha Flying Squirrel is similar to other flying

squirrels except of the color and other features. Like other flying

squirrels, the most distinctive feature of this species is the muscularmembrane that extends along the sides of the body, from the front legs

to the back legs. This membrane is like a parachute because when the

animal jumps form a tree to another tree, it is able to steer by moving its

legs and tail and controlling the membrane. The Namdapha Flying

Squirrel is found mostly in India and Asia.
