Kadalundi Mudflats

Sand sedimentation is causing the mudflats of Kadalundi to vanish.

  • Kadalundi – A village on the southwest coast in Kozhikode, Kerala that had about 8 hectares of nutrient­ rich inter­tidal mudflats in the early 2000s.

Kadalundi River is the 6th longest River of Kerala. It originates from the Western Ghats and has 2 tributaries Olipuzha and Veliyar. The Kadalundi River and the Chaliyar River merges with the Arabian Sea at Kadalundi.

  • Threat - Today, it has reduced to about 1 hectare.
    • Sedimentation of sand deprives prey to migrant birds.
    • Mangrove proliferation is aggressively invasive and they never attracts migratory birds because of predator’s presence.
    • Kerala floods of 2018 and 2019 hastened the process of degradation in Kadalundi.

The Kadalundi Bird Sanctuary is home to over a 100 species of native birds and about 60 species of migratory birds.

Kadalundi-Vallikunnu Community Reserve (KVCR) is India's 1st river front community reserve. It spread across the 1.5km2 and endowed with good patches of Mangrove forest.

Mudflats

  • They are also known as tidal flats which are coastal wetlands that form when mud is left behind by tides or rivers.
  • They’re found in sheltered regions such as bayous, lagoons, estuaries, and bays.
  • The majority of the sediment in a mudflat is within the intertidal zone, therefore the flat is submerged and exposed about twice per day and is usually barren (without any vegetation).
  • Importance - It is vital in preventing coastal erosion and act as habitat for birds.

Soil contains nearly twice the amount of carbon compared to the combination of the atmosphere, vegetation, and animals.
