Explanation:

 ? WWF: Brow-antlered deer: The deer walks on the hind surface of its pasterns with mincing hops over floating foliage, and is hence also called the Dancing Deer.
? Sangai faces threat from steadily degenerating habitat of phumdi as a result of continuous inundation and flooding caused due to artificial reservoir. Water quality of the reservoir is degrading due to pollution and stoppage of nutrient supply.
? There is also invasion of non-native plants like ‘Paragrass’.
? About ‘Phumdi’: The brow-antlered deer is found in Keibul Lamjao National Park in Manipur. It is largely seen over the floating biomass, locally called “phumdi” in the South Eastern part of Loktak Lake inside the park. Phumdi is the most important and unique part of Sangai’s habitat. It is the floating mass of entangled vegetation formed by the accumulation of organic debris and biomass with soil. Its thickness varies from few centimeters to two meters. It floats with 4/5 part under water.
? The Manipur Forest Department plans to translocate a section of the rare species of the endemic deer to ‘Pumlen Pat’, which is close to its existing habitat in Loktak.
