Wetland Havens Decline Amidst Bird Population Rise

The recent Asian Waterbird Census in Thiruvananthapuram district has revealed a complex picture for local wetlands. While the overall waterbird population saw a slight increase, with 4,868 birds from 73 species recorded, four vital sites are experiencing significant habitat degradation. These affected areas include the Punchakkari wetlands, Akkulam Lake, Veli Lake and beach, and the Kannammoola canal.

Volunteers identified unscientific infrastructure development, intense tourism, and other human pressures as primary drivers of this decline. Invasive plant species like water hyacinth are also proliferating, further impacting habitat quality. Despite these challenges, the presence of 37 migratory species highlights the importance of these wetlands for conservation efforts.
