This is a real incident that happened while I was doing research on mangroves in
Mangroves are trees that grow in the estuaries and their roots remain submerged during high tide. They have developed arial roots to breath. The mud flats are a very dangerous place to get stuck in. The mud is soft and just slides you into its clayey embrace very slowly indeed.
The Mangroves have a great ecological significance as it acts as a buffer zone against cyclones and tidal waves. A need to conserve and importantly, save them from being chopped down for development and as firewood. They are not easy to grow in nurseries and thus afforestation is not a viable option. It would rather be worthwhile to let them regenerate but restricting human activity. Completely sealing it off would result in a revolt, as local communities depend on it's rich waters for their livelihood.
