Moreover, mangroves rely on mud buildup from rivers to help them make the transition, but studies suggest that in at least some parts of the world, mud.

Treating animal hides with tannin alters the hides protein structure so it becomes soft, pliable, and resistant to decomposition. As the salty water evaporates, noticeable salt crystals often form on the surface of the leaves. Mangroves further improve water quality by absorbing nutrients from runoff that might otherwise cause harmful algal blooms offshore. Parasitic species cause such diseases as 'die-back' of mangroves, but the majority are saprophytic on wood debris and leaf litter, contributing as decomposers to the mangrove ecosystem's food chain. >> Honey can be a sweet luxury, but for many it is a way of life.
