Figure 3: Simulation output showing distribution of mangrove (dark) and hardwood hammocks on a  m2 model landscape. (a) Simulation with both spatial gradients in salinity input due to tides. (b) Simulation in which there is no environmental gradient of salinity input; the groundwater salinity is such that alternative stable states can occur over the whole area (from [44]).
