Centre Seeks Action from Maharashtra on Flamingo Habitat Concerns in Navi Mumbai

The growing ecological crisis in Navi Mumbai’s wetlands has drawn urgent attention from the Centre, which has directed the Maharashtra government to act swiftly to protect flamingo habitats that are rapidly deteriorating due to pollution and disruption of natural systems.

Flamingos, known for their striking pink plumage, are not just seasonal attractions but play a crucial role in maintaining ecological balance. By feeding on algae and small organisms, they help regulate nutrient levels in wetlands, preventing excessive algal blooms and supporting biodiversity. Their presence is widely regarded as an indicator of a healthy wetland ecosystem.

Globally, species such as the Greater Flamingo and Lesser Flamingo are classified under the International Union for Conservation of Nature ( IUCN ) Red List as “ Least Concern .” However, experts warn that this status does not diminish the growing regional threats they face, particularly due to habitat degradation, pollution, and human interference in critical wetland areas.

The alarm was raised on World Water Day , when environmental activists flagged a “ wetland emergency ” after water sample tests revealed severe contamination in the DPS, NRI, and T S Chanakya lakes at Nerul. These lakes serve as important satellite wetlands for the Thane Creek Flamingo Sanctuary , a Ramsar site that hosts thousands of migratory flamingos every year.

Tests conducted by the NatConnect Foundation revealed alarming levels of TDS , abnormal pH , and high BOD and COD , all pointing to severe ecological stress. Experts attribute this to blocked tidal flow , which has turned these wetlands into stagnant, polluted basins instead of naturally flushed ecosystems.

The situation is further underscored by the unusual absence of flamingos this season, particularly during the peak migration months. Environmentalists say this is a clear sign that the habitat is no longer suitable for the birds, reflecting a deeper environmental imbalance.

Key threats to these wetlands include discharge of untreated sewage and industrial effluents , encroachment , dumping of solid waste , and unregulated urban development. Obstructions such as fishponds and land reclamation activities have also disrupted tidal channels, preventing the natural cleansing process essential for wetland health.

Taking note of these concerns, the Union Ministry of Environment, Forest and Climate Change ( MoEFCC ) has asked the Maharashtra State Wetland Authority to address the issue on priority and submit an action taken report. The Centre has reiterated the provisions of the Wetlands Rules, 2017 , which strictly prohibit activities that alter the ecological character of wetlands.

Activists have held agencies like CIDCO (City and Industrial Development Corporation) and regulatory bodies accountable, alleging negligence and lack of enforcement. They warn that continued inaction could lead to irreversible damage to these vital ecosystems.

With flamingos serving as a symbol of wetland health, their disappearance from Navi Mumbai is being seen as a serious ecological warning. Experts stress that immediate restoration of tidal flow, strict pollution control, and protection of wetland boundaries are essential to revive the habitat and ensure the return of these iconic birds.
