Mangroves as indicators of coastal change

F. Blasco, P. Saenger, E. Janodet
1996 CATENA  
Consequently, the use of remote sensing data for mangrove ecosystems offers excellent potential as a tool for monitoring coastal change.  ...  In view of the unique biological characteristics of mangroves, it is interesting to assess the extent to which these ecosystems can be used as indicators of coastal change or sea-level rise.  ...  Here again, the rapidity and the scale of changes make the application of satellite data extremely useful for measuring the extent of changes and evaluating their consequences.  ...
