Introduction
See lion
facts for information on both subspecies of lion.
There are 359 Asiatic lions left in the wild (Gir National Park) at
April 2010 (this figure is quoted as being the same in 2006 as well4 - is it still
accurate?). It is said that in 1936 a survey resulted in an estimate of
234 animals in the Gir National Park. In April 2010, the authorities
say that a five yearly consensus at April 2010 will show that there is
a population of 400 in the park3.
The IUCN Red List of Threatened Species™ says that there
are approximately 175 mature individuals. 34 animals were
reported killed in 2007 (Jackson 2008). 72 have died in the past 2 years3.
There are
serious
concerns about the hybridization of captive Asiatic lions
(African x Asiatic). India now only breed purebred4. I think it
fair to say that the
situation at this time (2010) is not good for this very rare
subspecies of lion.
Yet the people living in the Gir National Park, where it is nly found,
mourned the loss of a five year old male lion that fell (or was pushed)
off a bridge over a 60 foot drop. It may have been traffic that forced
the lion off. He was killed in the fall3.
There is genuine concern from local people, but it seems that a
coordinated or truly
effective response to preserve this species is lacking.
This subspecies of lion is very similar in many ways to the African
lion. I limit this page to information that is specific to this
species. Please see Lion
Facts for lots of easily accessible information about the
lion in general.

The
low genetic variability of the Asiatic lion is not thought to be caused
by inbreeding but to be a "characteristic feature of this species"8. It is said
that from a genetic standpoint all these lions are like twins.
Description
and Difference from African Lion
The differences between the Asiatic lions and African
lions, both subspecies of the lion are listed below:
- the genetic difference between these subspecies
is "smaller than the genetic distance between human racial groups"11
- the Asiatic lion prides are smaller than those
of African lions, with an average of only two females. An African pride
has an average of four to six.4
- males are less social than African lions and
only associate with
the pride when mating or on a large kill.4
- they have less swollen tympanic bullae (a
thin-walled bony capsule which houses an extension of the cavity of the
middle ear, the tympanic cavity5)
- they have shorter postorbital constriction4 (this is wrong
on the face of is as this term applies to primates6
- a lion is not a primate)
- they usually have divided infraorbital foramen4 (an opening in
the maxillary bone just below the lower rim of the orbit that gives
passage to the infraorbital artery, nerve, and vein7)
- this might be doubted.
- the lion of Asia is generally smaller,
it is said
- the Asiatic lion nearly always has a flap of
skin (a belly fold) running the length of the belly from the fore to
the hind legs, while this flap is rare in the African lion.
- they have a thicker coat
- they have a longer tail tassel
- they have less of a mane1 although one text2 says that they have fuller
manes, which are more complete:

News
April 2010
Politics has entered the world of wild cat conservation again. It had
been thought that the Gir Forest sanctuary was too small. There were
fears of a disease killing a large part of the population. Central
government decided, in 1995, to move a handful of lions to the 133
square mile Kuno sanctuary in Madhya Pradesh by 2001, 9 yeas ago.
The
Gujarat government refuse the move. They probably foresee loss of
tourism business as 100,000 visit yearly. Yet the central government
has decided to ban
tourism to the reserves
as it is killing the tiger it is claimed. That is disputed. The move to
Kuno is also disputed and goes to court fro a decision. Gujarat says
that Kuno has a poor record of protecting the tiger and in any case the
preparations are not complete (some 15 years after the decision was
made to move the lions).
It sounds bad. And I think that this
politicizing of the conservation process and a lack of will to do
something damages the lion's and tiger's chances of survival.
Range
- Distribution
This has been much reduced over the years. Here is an extract from a
1832 book:
This less well known subspecies of lion once occupied habitat from the
Danube to the Ganges. Its historic distribution extended across
southwest Asia.
It now only occupies the Gir Forest sanctuary in
north east India, in the state of Gujarat. The Red List says that this
isolated population extends beyond the boundaries of the sanctuary.
This sanctuary is 617 square miles in area (1,598 km²). The habitat is
a dry teak forest. Teak is replanted by the authorities as logging
takes place.

the lion generally as at late 2009.
History
Notes
In 1832 there were a couple of Asiatic lions inhabiting the Tower of
London the well known landmark in the east side of central London,
England.
These lions, brother and sister, were the offspring of two lions,
father
and mother shot by
General Watson. It was 1823 and the general was on horseback with his
double barrelled rifle. He was approached by a male Asiatic lion and he
shot it dead. The female approached and he wounded her. He followed her
back to her den and shot her dead. There were two young cubs, which he
took and raised them with the aid of a donkey. He shipped them back to
England as a gift for the King, Henry I, who had them confined to the
Tower of
London.
The brother and sister mated and produced three cubs on 20th October
1827. They were the first to be born at the Tower since 17942.
In the Middle Ages lions were kept in menageries in Europe. In England
the King's menagerie was in the Tower of London. Apparently he
discontinued this
practice in 18402.
Threats
and Conservation
The population is considered stable although this lion is critically
endangered per IUCN Red List of Threatened Species™:

Threats11:
- falling down wells (there has been a campaign
to cover 13,5003).
- as the entire population of Asiatic lion is in
one place there is a risk of a catastrophic loss of numbers through
fire or epidemic.
- poaching. Poaching is a problem for the Bengal
tiger in India. Poachers who would take the tiger are now going for
lion. This maybe because it is easier to find. The Bengal tiger is
extirpated in some tiger
reserves. They are hard to see and find even for
poachers.
- is inbreeding
a problem? I am not sure. The population of lions is low. Is it a
sustainable population? Inbreeding causes low fertility.
Conservation11
consists of protecting the lions in the Gir Forest and establishing a
second population as described above.
There was a previous failed attempt at establishing a second population
in Chandraprabha Wildlife Sanctuary in eastern Uttar Pradesh. The lions
were lost - shot or poisoned.
The Asiatic lion is listed under CITES Appendix I. CITES
in relation to Cats. See IUCN
Red list in relation to cats.
