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 6^th 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 1^st 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.
