This is called blue carbon. With their roots submerged in water, mangrove trees thrive in hot, muddy, salty conditions that would quickly kill most plants. >> 27-29 March, 1991 pp. 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. Part of her research includes carefully dosing individual mangrove trees with small amounts of nitrogen and phosphorus to understand howexcess nutrients, which are a major global threat to mangroves and other coastal ecosystems like those from industrial, residential, and agricultural sourcesaffect mangrove ecosystems.

While most terrestrial plants use whats called a taproot to burrow deep into the ground for support, several mangrove species rely on sprawling cable roots that stay within a few centimeters of the soils surface for stability and access to oxygen.
