Describe the habitat condition, flora and fauna: the three ecozones of Uttar Pradesh.

Terai–Bhabar ecozone

• Habitat: high rainfall, high water table, bhabar pebbles that swallow streams, terai marshes, sal forest, and tall elephant grass; frost is rare, flood and waterlogging are not.
• Flora: sal, teak plantations, khair–sissoo on new alluvium, grasslands (elephant grass, Saccharum types), and swamp edge herbs.
• Fauna: tiger, elephant, rhino (reintroduced pockets), swamp deer, hog deer, hispid hare, Bengal florican, gharial and Gangetic dolphin in Girwa–Ghaghara; this is the big-mammal ecozone.
• Condition today: fragmentation by cane and paddy, railway and road cuts, and grass-fire or grass-loss that starve swamp deer.

Gangetic Plain ecozone

• Habitat: deep alluvium, monsoon rivers (Ganga, Yamuna, Ghaghara, Gomti, Rapti), oxbows, tals, and almost complete conversion to agriculture; natural habitat is now the river edge, floodplain pocket, and notified jheel.
• Flora: little climax forest left; mango, mahua, babul, dhak, and planted eucalyptus–poplar sit with crops; wetland macrophytes in sanctuaries such as Nawabganj and Samaspur.
• Fauna: Gangetic dolphin and turtles in main stems, sarus crane in paddy–wetland mosaics, migratory ducks, mugger in some rivers, and a thin jackal–nilgai farm fauna; gharial is largely a Chambal (plain-ravine edge) story.
• Condition today: pollution, sand mining, river training, and eutrophic jheels; the ecozone feeds India and still hosts river endangered species if flow and sewage are managed.

Vindhyan–Bundelkhand ecozone

• Habitat: Archaean and Vindhyan rocks, seasonal streams, tanks, ravines (Chambal–Yamuna), dry deciduous and thorn forest, hot summers and drought.
• Flora: teak and mixed dry deciduous (tendu, palash, kardhai, khair), grasslands on plateaus, and ravine scrub; sal is not the dominant terai story here.
• Fauna: sloth bear, leopard, wolf and hyena in ravines, blackbuck in open patches, gharial and rare turtles on Chambal sandbanks, and a returning tiger landscape at Ranipur–Kaimoor.
• Condition today: mining dust, fuelwood, and tank silt; ravines are both a gharial fortress and a degraded farm edge.

Reading the three together

• Do not plant a terai tiger answer on a Bundelkhand question, or a sal list on the doab.
• Conservation is zone-specific: grass and corridor in terai, river flow in the plain, tanks and dry forest in the south.
