Danger of extinction

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. A census conducted in 2000 in the park showed that there were just 162 deer (54 stags, 76 hinds and 32 fawns).^[4]

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 1983 the 103 megawatt capacity Loktak hydroelectric power project was commissioned with the objective of ensuring rapid development in the State. A maximum high water level of 168.5 meters (553 ft) above mean sea level (MSL)is maintained in the Loktak Lake to feed the reservoir for the hydel project. This high water level had wreaked havoc in the Keibul Lamjao National Park. The high water level, maintained continuously 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 nutrients—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 lakebed 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 National Park had broken up into pieces and had drifted freely from the park area. This was a bad sign for the Sangai habitat. It spelled out very clearly that the beginning of the end of the Sangai habitat had begun. There are reports of local people cutting up the phumdi into sizable 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.
