Tannins and other dyes are extracted from mangrove bark. As this review highlights, however, hazard mitigation by tidal wetlands is limited to certain conditions, and not all hazards are equally reduced. (2) Microbial communities receive food from mangrove root exudates and can help recycle nutrients (Bashan and Holguin, 2002). Standing water covers the aerial roots, making it impossible for oxygen to reach these specialized roots as well as the underground root systems.
