The fast disappearing 'kavu' (small bushy thick forest) and ponds and other water bodies are the remnants of this ancient geography of the region.

Being a mangrove forest, biodiversity thrived in the region- varieties of fishes, plants, animals, birds.

It might have taken a long time to start the settlement in ancient Kandalloor because of scarcity of fresh water, land unsuitable for agriculture, non-navigable land covered with thick forest, plenty of insects and poisonous creatures, etc.

A big population of 'Mukkuvan' community still live in the western bank of Kayamkulam backwater ('Kayal' in local language).

Next major settlement might have started by people migrating from north towards south clearing the forest changing the land shapes to make it inhabitable.
