Revision summary
U.P. tarai sanctuaries are Dudhwa TR (Kishanpur, Katarniaghat), Pilibhit, Suhelwa, and Sohagibarwa. They protect a rare sal–grassland–floodplain mosaic on the Nepal edge. Fauna include tiger, elephant, barasingha, rhino effort, and grassland specialists. Rivers add dolphin and gharial value at Katarniaghat. Importance is process: flood, grass, corridor, and recharge, not only tourism.
Model answer
Introduction
The Tarai sanctuaries of Uttar Pradesh — Kishanpur and Katarniaghat with Dudhwa as the tiger-reserve core, Pilibhit’s forests, Suhelwa, Sohagibarwa, and allied wetlands — are the last great sal–grassland–floodplain mosaic on the Indo-Nepal edge. Ecological importance is tiger and elephant room, swamp deer and grassland birds, river corridors, and recharge. They are not ornamental parks on a tourist poster.
Body
The Tarai set
- Dudhwa National Park plus Kishanpur and Katarniaghat Wildlife Sanctuaries form Dudhwa Tiger Reserve, the state’s flagship tarai block.
- Pilibhit Tiger Reserve continues the sal–grass belt westward; Suhelwa (Balrampur–Shravasti) and Sohagibarwa (Maharajganj) hold the eastern tarai–bhabar forests.
- Floodplain wetlands and riverine stretches (Ghaghara, Sharda, Mohana, Suheli) are part of the same ecology even when notified separately.
Why the mosaic matters
- Terai-Duar savanna and grassland is a globally rare ecoregion: tall grassland, swamp, and sal on a flood-pulse. Drain it for farm and the barasingha goes with the grass.
- Swamp deer (barasingha) at Dudhwa, tiger, elephant, rhino reintroduction, hispid hare, hog deer, and Bengal florican make the belt a unique plains fauna, not a leftover of the hills.
- Trans-border corridors toward Nepal’s Bardia and Shuklaphanta keep genes moving; a fenced sanctuary without a corridor is an island that will inbreed.
Services beyond the charismatic
- Flood attenuation, groundwater recharge, and sediment capture on the tarai fan protect the sugarcane-paddy belt that pressed against the forest.
- Carbon in sal and grassland, and non-timber livelihoods for Tharu and other forest-edge communities, are ecological-economic services if rights and grazing are managed, not denied in name only.
- River dolphin and gharial stretches on Ghaghara–Gerua (Katarniaghat) extend importance from forest to aquatic.
Threats that define importance
- Encroachment, sugarcane right up to the grass, railway and NH kills, and invasive species shrink the mosaic the sanctuaries exist to hold.
- Ecological importance is therefore conservation of process — flood, fire in grassland, corridor — not only a tiger photograph.

Conclusion
Tarai wildlife sanctuaries in U.P. matter as the sal–grassland–floodplain engine of Dudhwa–Katarniaghat–Kishanpur, Pilibhit, Suhelwa, and Sohagibarwa. They keep tiger, elephant, barasingha, and river fauna, recharge the fan, and hold a Nepal corridor. Lose the grass and the flood pulse, and the sanctuary is only a sal woodlot.

-
Is Dudhwa a sanctuary or a national park?
Dudhwa itself is a national park. Kishanpur and Katarniaghat are wildlife sanctuaries; together they form the tiger reserve that is the tarai core.
-
Why are grasslands as important as sal?
Because barasingha, florican, and hog deer are grass species. Sal alone is a timber story; the mosaic is the ecology.

Agriculture and forestry of UP
U.P. Agriculture Export Policy 2019 applies the national export frame to state clusters. ODOP and GI products are the named commodities, not a new crop list. Pack houses, cold chain, and Budget-backed logistics are the hardware. Invest U.P. and MSME processing convert surplus into a shippable pack. A cluster without phytosanitary discipline and a buyer remains a slogan.

What are the key features and significance of the Lower Ganga Canal System in Uttar Pradesh?
Geography of UP
The Lower Ganga Canal takes off at Narora Barrage in Bulandshahr. It irrigates the central and lower Ganga–Yamuna doab through Kanpur and Fatehpur branches. It is a surface irrigation system, not a hill power canal. Significance is food security and a possible brake on groundwater mining. Tail-end supply, lining, and drainage decide whether that significance is real.
