Abstract

Aerial roots are a common adaptation of mangrove trees
to their saline wetland habitat, allowing root respiration in the anaerobic substrate. While mangroves flourish on
sedimentary shorelines, it is shown here that excess input
of sediment to mangroves can cause death of trees owing
to root smothering. Descriptions of 26 cases were found in
the literature or described here, where mangroves have
been adversely affected by sediment burial of roots. The
impacts ranged from reduced vigour to death, depending
on the amount and type of sedimentation, and the species
involved. There are insufficient data to establish speci®c
tolerances. For rehabilitation, where the disturbance was a
past event, the elevation change must be assessed in
selection of species for replanting, and field trials are
required in areas where rapid accretion is an ongoing
problem.
