Temporal Stability of Mangrove Multispectral
Sustainable management of mangroves depends on our ability to maintain ecosystem functions. It requires a careful monitoring of several forest characteristics such as the species composition. Very high resolution multispectral satellite images provide pivotal information at the individual tree scale that may support identification and mapping of species of mangrove trees emerging at the canopy level. In this study, we showed that fine scale spectral responses of 4 common Asian mangroves species were and remained distinct over one decade and, independently of both the satellite sensor and the angular configurations of images acquisitions. We began physical interpretation of such original and promising observations using a 3D radiative transfer modeling approach.
