Vanishing Species - The Sangai

An Article by Mohan Pai

The Sangai
Cervus eldi eldi

The Sangai, the brow-antlered deer is found only in Manipur and only 162 animals survive.
The Sangai was believed to be almost extinct by 1950. However, in 1953 six heads of the Sangai were found hovering at its natural habitat. Since then, the State Government has taken serious and positive measures for the protection of this rare and endangered species. The Sangai is also the state animal of Manipur and is projected as the social and cultural identity of the state..The Sangai lives in the marshy wetland in Keibul Lamjao National Park( 40 sq km). Its habitat is located in the southern parts of the Loktak Lake, which is the largest freshwater lake in Eastern India. It is also one of the seven Ramsar sites of international importance. The habitat of the Sangai is now a protected area.

The Sangai Forum was formed to protect the Sangai and other wildlife like hog deer, wild boar, Indian otter, civet cat, box turtle, and migratory water birds who have their home in the National Park. Although banned by law, hunting of the Sangai and other wildlife continues. Then again people hunt the deer for its meat. The Loktak Hydroelectric Power Project too has become a threat to the Sangai habitat. A constant high water level is maintained in the lake and this has led to many changes, one of which is the rise in the water level in the Keibul Lamjao National Park during the rainy season. Manipur experiences heavy rains during the monsoon season. So, the Sangai's home is constantly threatened. What happens during the rainy season is that the deer seeks shelter in isolated dry patches in the National Park and poachers lie in wait for such opportunity. Many times the deer drown. One of the duties of the Sangai Forum volunteers is to keep a watch for signs of danger. They organise search parties to locate deer that are in trouble inside the park. They also keep a lookout for the poachers and organise awareness campaigns in villages, stressing on the importance of the Sangai and the need to save it. The villagers are requested to report to the nearest Sangai Forum unit if they have any news of the deer in danger. Forum volunteers also work with Forest officers and forest guards to protect the deer. In January 2003, Sangai Forum volunteers caught two poachers who had killed a Sangai. The poachers were handed over to the local Police Station and a criminal case was filed against them.
Present status:It is reported that there are only around 162 Sangai deer left in Keibul Lamjao National Park.This last natural habitat of the deer - covering a total of 40.5 sq.km with a core zone area of 15 sq.km, is peculiar by itself as it is mostly made up of the floating biomass locally known as Phumdi. The KLNP forms part of the southern portion of the greater Loktak lake, and so the park is within the water body area of the Loktak. It is for this reason that the park has often been termed as the 'only floating national park in the world'.

The Sangai faces a two-pronged danger to its life. Firstly, its habitat is steadily degenerating by reason of continuous inundation and flooding by high water caused as the result of artificial reservoir of the Loktak hydroelectric power project. Secondly, poachers are out there to trap and slay the deer at the slightest opportunity. In February 1998 poachers trapped two Sangai doe inside the KLNP, killing both female.

In 1983 the 103 Megawatt capacity Loktak hydroelectric power project was commissioned with the objective of ensuring rapid development in the State. One failure of the project has been that it has never been able to provide regular power supply to the villages in the Loktak lake periphery. And a very disturbing effect of the project has been its share of harm to the ecology and the environment of the Loktak, threatening the lake ecosystem, the humans and their lands, the wildlife, and all other life forms dependent on the lake for their living.
A maximum high water level of 168.5 meter above MSL is maintained in the Loktak Lake to feed the reservoir for the hydel project. At this level, much of the land on the periphery of the lake had been submerged under water, rendering huge loss of productive agricultural lands and localised fish culture farms. On the other hand, this high water level had wreaked havoc in the KLNP. The high water level, maintained continuously through the year, had disturbed the natural life cycle of the vegetation growth, the through the year, had disturbed the natural life cycle of the vegetation growth, the phumdi, upon which the Sangai thrives. The deer feed on several types of vegetation that grow on the phumdi. The vegetation also provides shelter to the deer and other wildlife in the park.

The life-cycle of the phumdi involves floating on the water surface during season of high water as in the monsoons. In the lean season, when the water level reduces, the biomass come into contact with the lake bed and they secure the required nutrient from there. When the rains come again and they become afloat, the biomass have enough 'food' - the nutrient - stored in their roots and their life continues. What is happening now, according to local scientists who are studying the phenomena, is that with continuous high water in the lake throughout the year much of this process of 'feeding' on the nutrient in the lake bed had discontinued. The result - the biomass are losing weight and getting thinner by the year. Around January last week in 1999, it was reported that a large chunk of the biomass in the northern part of KLNP had broken up into pieces and had drifted freely from the park area. This was a bad sign for the Sangai habitat.
Very recently this year, reports came in about local people cutting up the phumdi into sizeable pieces and then towing away these with dugout canoe for 'selling' to fish culture owners. This is another potential danger to the Sangai habitat. It meant humans are now aiding the process of annihilating the habitat area, supplementing to the rapid degeneration of the habitat.

Conclusion:
The Sangai - a jewel in the crown for Manipur - is one of the most unfortunate animals living in the world today. Human activity - read development process - had caused extensive damage to its last natural habitat, threatening its very existence. Humans continue to hunt and slay the deer on the sly in spite of legislation (Manipur Wildlife Protection Rules 1974) and public outcry. There is no State sponsored conservation programme for securing the safety of the deer and its habitat. Manipur is poised to lose this animal wealth, forever, if timely help does not come now.

Vanishing Species - The Wild Boar

An Article by Mohan Pai

The ‘Varaha’ of the Hindu mythology (the 3rd Avatar of Lord Vishnu) is the Wild Boar of the Indian Jungles.

You would do better to be on your guard against this animal when in the jungle. This is the species that has the guts to challenge even the tiger. With typical pig-like features, an average wild boar rises to a height of 90cm, and weighs more than 100 kg, although some can weigh as much as 225 kg. The most distinctive feature of the wild boar is a pair of elongated canines that grow upward and outward. It wears a greyish-black coat that is scantily covered with thick bristle-like hairs arising from its nape and winding their way to its posterior. The wild boar has an incredible sense of smell, although it has fairly average eyesight and hearing. Its body is well built, but what really makes it stand out is its courage and determination to live and to win the wild bouts. Its thick coat with its layer of fat helps it recover even from the gravest of injuries. It is not an unusual sight to see a herd of 5-6 animals grazing silently in the middle of the forest, but come nightfall, and the herd becomes really confident. Wild boars are known to raid and damage crops of the farmers living on the peripheries of National Parks and Sanctuaries. Amazingly, wild boars do not have any fixed cycle for breeding. But whenever it is the mating season, a fair and formal contest decides the dominant male who gets to mate with the female boar. After a gestation period of four months, the mother gives birth to 4-6 cubs. Thanks to poaching and the loss of habitat, the number of the wild boars is fast decreasing. Once there were 6-7 species found in the sub-continent, but today only two species survive. The widespread Indian Wild Boar(Sus scrofa cristatus and the very rare and recently rediscovered Pigmy Hog (Sus salvanius) which occurs in northern Assam.


Wild boar is considered to be the wild antecedent of the domestic pig of the Indian subcontinent. It belongs to the Suidae biological family, which also includes the Warthog and Bushpig of Africa, the Pygmy Hog of northern India and the Babirusa of Indonesia. Indian wild boars are also quite closely related to peccary or javelina of North, Central and South America.
“These creatures, found all over India, have become very wary and are difficult to photograph because of widespread persecution. They are generally classed by States as vermin because of their habit of raiding food crops, and can be shot by anyone at any time. In addition they are much relished as a meal by tigers and leopards and by lions of Gir forests, though a large boar can be more than a match for a tiger or a lion.These are the same animals that are the quarry in the well-known sport of pig-sticking, which still takes place in north India where there is flat, grassy terrain suitable for horses to gallop over.” -- E. P. Gee.

Physical Traits

The thick coat of the wild boar of India is grayish-black in color and is covered with bristle-like hair. It can grow up to a length of 6 feet and may weigh as much as 440 lb (200 kg). The features of a wild boar are quite similar to that of a pig. It has a prominent ridge of hair, which match the spine. The tail is short and straight and the snout is quite narrow.
The most noticeable as well as most distinguishing feature of the wild boars comprise of a pair of extended canines. These canines grow both upward as well as outward. Indian wild boars possess an acute sense of smell. Even their eyesight and hearing power is fairly strong.
Behavior

Wild boars can be found roaming around in groups, known as sounders. The number of sows, in a characteristic sounder, is two or three and rest of the members are the young ones. A typical sounder comprises of 20 animals on an average. In exceptional cases, the membership of a sounder may go up to 50 also. Adult males join a sounder only during the mating period and for the rest of the year they prefer to stay alone. Indian wild boars are basically nocturnal creatures, which forage from dusk to dawn. When surprised or attacked, they may get aggressive.
Diet

Wild boars eat anything and everything, including nuts, berries, carrion, roots, tubers, refuse, insects, small reptiles, etc. Young deer and lambs may also form a part of their diet.
Habitat

Wild boar is found inhabiting the woodlands of Central Europe, Mediterranean Region (including North Africa's Atlas Mountains) and most of Asia (including India).
Mating Behavior

There is no fixed mating period of the wild boars of India. However, whenever it takes place, it results in a formal contest between the males to decide the dominant male. The winner gets to mate with the female boar. The maturity period is one year and gestation period lasts for four months. A female wild boar usually gives birth in the spring season and the litter normally consists of 4 to 6 cubs.

Status

The population of Indian wild boars is declining at a fast pace. The reasons for this are large scale poaching as well as habitat destruction. At some point of time, Indian sub-continent consisted of 6-7 species of wild boar. However, today only two of them are left.
Subspecies Sus scrofa scrofa (North Africa, Europe, and Asia) Sus scrofa ussuricus (North Asia and Japan) Sus scrofa cristatus (Asia Minor to India)Sus salvanius (Pigmy Hog) - (India) Sus scrofa vittatus (Southeast Asia to Indonesia)

The Pigmy Hog
The Pigmy Hog is so secretive and limited in distribution that it was thought to be extinct until 1971 when an animal was authentically sighted and then specimens were captured. They are diminutive in size, adult male weighing about 9 kg and standing 23 to 30 cm at the shoulder, while adult female weighs about 6 kg. They are shy and secretive, with family groups spending the day burrowed under a nest which they construct of piled-up chopped sedge and grasses hidden in some thicket. They move with lightning rapidity through the thick vegetation and when confronted are bold, aggressive and can inflict severe lacerations with their razor-sharp incisors. The entire world population is presently believed to survive along a narrow foothill belt in the extreme northeastern border of Assam. Recent studies have shown that females produce only one litter a year and that is born in April or May during the dry season.
