Why are flamingos avoiding Nerul wetlands in Navi Mumbai?

Flamingos are avoiding Nerul wetlands due to a sharp decline in habitat quality, caused by severe pollution, high TDS levels, alkaline pH, and critically low oxygen, making the ecosystem uninhabitable.

What are the main causes of pollution in Navi Mumbai's wetlands?

The deterioration is largely attributed to disrupted tidal exchange, where blocked drainage channels trap polluted water, leading to algal blooms and a collapsed ecosystem.

What steps are being taken to address the wetland crisis?

Authorities have initiated cleanup operations and are directed to address blocked inlets. A joint inspection is planned, with activists pushing for restoration of natural water flow as a long-term solution.

Flamingos Shun Toxic Navi Mumbai Wetlands

Migratory flamingos have begun avoiding crucial wetlands in Navi Mumbai, including those in Nerul, which were once reliable feeding grounds. Birdwatchers observed flocks flying over these areas without landing, indicating a significant decline in habitat quality and ecological health.

Recent water quality analyses commissioned by the NatConnect Foundation have highlighted severe ecological stress. The tests showed extremely high levels of Total Dissolved Solids (TDS) and alkaline pH, alongside critically low oxygen levels due to elevated Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD). This has created a 'suffocated' ecosystem unsuitable for life.
