Wildlife of
Odisha

The main land biome in much of Odisha is tropical deciduous forests (sal and mixed deciduous), with drier scrub in rain-shadow areas; large blocks in Eastern Ghats and Similipal, fragmented woodlands in plains.

Widespread inland; the largest share of natural terrestrial cover, especially in hill/plateau districts and reserved forest tracts.

Occurs as small, localized moist evergreen to semi-evergreen patches and riparian evergreen stretches in wetter parts of the Eastern Ghats and sheltered valleys; also includes structurally 'rainforest-like' semi-evergreen forest remnants within a broader deciduous matrix.

Patchy and limited; mainly in wetter hill pockets and along perennial stream valleys.

Open forest-grassland mosaics and park-like woodlands, including grassy openings in forest landscapes (e.g., meadows/grasslands within large protected areas) and coastal/inland open habitats maintained by flooding, grazing, fire, or soil constraints.

Local to scattered; embedded within forest landscapes and parts of the coastal/inland plains.

Large river networks, floodplains, reservoirs and oxbow/seasonal wetlands; strong monsoonal flow regime shaping sandbars, riparian belts, and floodplain lakes/pond systems.

Statewide along major basins (Mahanadi system; Brahmani-Baitarani; Subarnarekha; Rushikulya) and associated floodplains/reservoirs.

Extensive deltaic and floodplain wetlands, marshes, swamps, and brackish lagoons; includes globally significant wetland complexes such as Chilika (brackish lagoon) and Bhitarkanika's tidal wetlands/mudflats.

High along the coast and river deltas; also common as inland floodplain/seasonal wetlands during and after monsoon.

Nearshore Bay of Bengal waters with sandy seabeds, estuarine plume zones, and productive coastal fisheries; includes turtle nesting beaches and nearshore feeding areas influenced by river discharge and seasonal currents.

Along the entire Odisha coastline and adjacent continental shelf waters.

Large protected and managed forest tracts in the Eastern Ghats and northern uplands; key tiger/elephant landscapes include Similipal and Satkosia-linked forests (where contiguous habitat remains).

Sal (Shorea robusta) and mixed deciduous forests dominate many hills and plateaus; strong seasonality with leaf-fall in dry months and monsoon-driven regeneration.

Small semi-evergreen/moist evergreen pockets in wetter hill tracts and sheltered valleys; higher canopy complexity and evergreen understory relative to surrounding deciduous forests.

Degraded forest edges, secondary growth, and open-canopy sal/mixed stands forming transition zones between villages/agriculture and denser forests.

Natural and semi-natural grasslands in riverine sandbars, floodplains, coastal stretches, and grassy openings within protected areas; important for grazing and ground-nesting fauna.

Dry scrub and thorny secondary vegetation in rain-shadow or heavily disturbed areas; common on poor soils and around degraded forest margins.

Eastern Ghats hill ranges and associated plateaus/valleys create elevational and microclimatic gradients, with cool moist pockets and rocky slopes supporting distinct plant communities.

Major monsoon rivers (Mahanadi, Brahmani, Baitarani, Subarnarekha, Rushikulya) with braided reaches, riparian belts, and dynamic sandbar habitats.

Chilika Lagoon (brackish, lagoonal 'lake' system) as a flagship; also includes inland reservoirs and natural lakes/large ponds supporting waterbirds and fisheries.

Village tanks and seasonal ponds widely distributed in agrarian landscapes; important for amphibians, waterbirds, and local water storage.

Deltaic/floodplain wetlands and seasonal inundation zones across coastal plains; key bird habitats and flood buffers.

Backswamps and low-lying waterlogged areas in deltas and floodplains, including freshwater and mildly brackish swampy tracts in the coastal plain.

Reedbeds and sedge marshes around Chilika and in floodplain wetlands; critical for migratory waterfowl and nursery habitat for fish.

Bhitarkanika and associated Mahanadi-Brahmani-Baitarani delta mangrove systems, with tidal creeks, mudflats, and high estuarine productivity (noted for salt-tolerant mangrove assemblages and estuarine crocodile habitat).

Large estuaries and tidal creek networks where major rivers meet the Bay of Bengal (e.g., Mahanadi delta complex), driving salinity gradients and nutrient-rich waters.

Long low-lying coastline with dunes, strand vegetation, and coastal wetlands; strong cyclone and storm-surge influence shapes geomorphology and habitat turnover.

Extensive sandy beaches including key nesting areas for olive ridley sea turtles (notably along parts of the Odisha coast such as Gahirmatha/Rushikulya sectors).

Limited and localized compared with sandy coastlines; small rocky/intertidal patches occur around certain headlands and engineered coastal stretches, supporting distinct intertidal assemblages where present.

Coastal Bay of Bengal waters supporting pelagic fisheries and migratory marine fauna; influenced by monsoon-driven upwelling/river plumes seasonally.

Predominantly sandy and muddy continental shelf seabeds offshore from deltas/estuaries; benthic habitats shaped by sediment loads and turbidity.

Intensive rice-based systems in coastal plains and deltas; mixed cropping inland; agriculture strongly coupled to monsoon hydrology and wetland mosaics.

Localized plantations (e.g., cashew on coastal uplands/dunes; timber and fuelwood plantations such as eucalyptus/acacia in some areas) embedded within agricultural/forest matrices.

Urban and industrial-coastal nodes (e.g., Bhubaneswar-Cuttack region, coastal ports) creating fragmented habitats and peri-urban wetlands under pressure.
