For the first time, Uttar Pradesh is taking a census of otters in its protected areas. The census has begun in the Pilibhit Tiger Reserve (PTR).
Otters live on fish and spend much of its time in or close to water bodies. A thriving population of otters means a healthy ecosystem. A growing or healthy population of otters means the water bodies are pollution-free. Clean water bodies mean a healthy ecosystem of the forest. Otters thriving and getting sufficient food to eat means the water bodies in the reserve are in a fine state and the aquatic life in them is healthy.
India is home to 3 of the 13 species of otters found worldwide. These are :
- Eurasian Otter (Lutra lutra) – IUCN status: Near Threatened.
- Smooth-coated Otter (Lutra perspicillata) – IUCN status: Vulnerable.
- Small-clawed Otter (Aonyx cinereus) – IUCN status: Vulnerable.
Pilibhit Tiger Reserve
Pilibhit Tiger Reserve spreads across Pilibhit district, Lakhimpur Kheri District and Bahraich District of Uttar Pradesh. The Northern edge of the reserve lies along the India-Nepal border while the southern boundary is marked by the river Sharada and Khakra.

The bomb cyclone swept has through the US Great Plains resulting in blizzard conditions, hurricane-like winds, snow and heavy rain and subsequent flooding.
Bomb Cyclone or Bombogenesis
Bomb Cyclone or bombogenesis refer to a rapidly intensifying area of low-pressure winter storm when there is a pressure drop by at least 24 millibars in 24 hours. The decrease of the pressure intensifies the storm. This pressure drop intensification and subsequent winter storms result in strong winds, beach erosion and coastal flooding, especially with high tide.
Bombogenesis storm can be tropical or non-tropical and proximity to a large body of water, particularly an ocean, during cold months contributes to the creation of a bomb cyclone.
Bomb Cyclone is caused by a collision of warm air and cold air which develop into rotating storm-like pattern and lead to an explosive deepening of pressure. Worldwide about 40 to 50 ‘bomb cyclones brew each year.
