Limiting salt intake Red mangroves exclude salt by having significantly impermeable roots which are highly suberised, acting as Current estimates of mangrove coverage are 91.46 km2 in Trinidad and 2.23 km2 in Tobago. Black mangroves are vulnerable to changes in tidal fluxes due to the type of marsh impoundment used for mosquito control, as overflooding or hypersaline conditions can occur (Rey et al., 1990).
