In-Depth Highlights
1. Deep Dive: Kazhuvelli Wetlands
Kazhuvelli is the second-largest brackish water ecosystem in South India. Its dynamic tidal channels create a mosaic of habitats that sustain diverse flora and fauna. During migratory seasons it serves as a vital stopover and breeding ground for a variety of bird species, while also supporting vulnerable reptiles and native plant species. Historically renowned for salt extraction—and mentioned in ancient literature—the area now faces modern challenges such as overfishing and salt pan expansion. Conservation initiatives, including Ramsar designation and community-led restoration projects, are vital to safeguarding this unique ecosystem.
