1. Ecological Overview & Biome Classification
Nalabana Bird Sanctuary (Chilika Lake) is a key protected wildlife sanctuary in Khordha, Odisha. Encompassing 15.53 square kilometres, the reserve occupies an essential conservation niche within the Eastern Ghats & Coastal Mahanadi Delta biogeographic zone of India. The terrain spans an elevation range from 0 to 2 above sea level, producing specialized micro-climates, undulating ridges, and secluded forest glades that sustain diverse indigenous flora and fauna.
The reserve provides an essential ecological buffer against habitat fragmentation in Khordha. Multi-tiered canopy cover, soil moisture retention, and perennial drainage sustain dense undergrowth and rich forage across the protected perimeter.
2. Conservation History, Legal Status & Biogeographic Role
The conservation history of Nalabana Bird Sanctuary (Chilika Lake) traces back to its formal notification in 1987 under the Wildlife (Protection) Act, 1972. Prior to statutory protection, the forest tract experienced pressures from timber harvesting and cattle grazing. Following notification, commercial felling was banned, livestock access regulated, and anti-poaching checkpoints established along sensitive ingress corridors.
Today, the sanctuary holds IUCN Category IV protected area status for species and habitat management. It forms an integral link within the regional conservation network of Odisha, establishing corridor connectivity with nearby reserve forests and national parks. This landscape connectivity prevents genetic isolation among wide-ranging mammals, facilitating seasonal dispersal across the wilderness matrix.
3. Hydrological Lifelines & River Catchments
Hydrologically, Nalabana Bird Sanctuary (Chilika Lake) is sustained by the drainage network of the Chilika brackish coastal lagoon / Daya and Bhargavi river distributaries of Mahanadi. Perennial streams, seasonal hillside nullahs, and natural forest pools traverse the valleys, creating essential drinking watering holes and seepages. These water bodies are vital for resident wildlife, drawing herbivores and dependent predators during early dawn and late dusk.
Seasonal rains replenish streams and forest pools across Khordha. Soil moisture retained in the humus layers enables vegetation to persist through dry spells, while forest department check-dams ensure reliable water availability year-round.
4. Forest Classification & Botanical Diversity
The forest cover of Nalabana Bird Sanctuary (Chilika Lake) is scientifically classified under Champion & Seth forest types as predominantly Submerged estuarine island wetland, intertidal mudflats, and halophytic marsh vegetation (Champion & Seth 4B/TS2). The botanical profile reflects the soil chemistry, elevation range, and rainfall patterns of Khordha, displaying distinct canopy layers ranging from mature timber trees to dense shrubby understories and ground cover.
The upper canopy features keystone trees including Phragmites karka, Scirpus littoralis, Potamogeton pectinatus, Ruppia maritima, Halophila ovalis, and extensive underwater macroalgal beds., offering vital nesting cavities and seasonal fruit. Beneath the primary canopy, intermediate trees and bamboo thickets provide sheltered forage for herbivores.
5. Flagship Fauna, Avifauna & Keystone Species
The biodiversity of Nalabana Bird Sanctuary (Chilika Lake) is distinguished by its flagship indicator species, the Greater Flamingo & Irrawaddy Dolphin (Phoenicopterus roseus & Orcaella brevirostris). The presence and steady population density of this indicator species reflect the ecological health and prey base of the reserve. Alongside the flagship species, the mammalian guild includes prominent herbivores and carnivores such as Bengal Tiger, Asian Elephant, Indian Leopard, Gaur, Sloth Bear, Sambar, Fishing Cat, Irrawaddy Dolphin.
The sanctuary's birdlife is remarkably diverse, making it a valuable destination for birdwatchers and ornithological researchers. Resident woodland avifauna including Greater Flamingo, Bar-headed Goose, Black-necked Stork, White-bellied Sea Eagle, Indian Skimmer thrive across the multi-tiered canopy. During winter months, wetlands and riverine stretches welcome migratory species arriving along continental flyways. Forest streams and leaf litter harbor Saltwater Crocodile, Olive Ridley Sea Turtle, King Cobra, Mugger Crocodile, Indian Rock Python, alongside diverse amphibians that underpin the food chain.
