 The mangrove in Indonesia is really, really important for us and our country because the mangrove is the highest of carbon stocks compared to all the tropical forests and also the mangrove can have the function to preserve and conserve the ecosystem. We monitor the mangrove, we use the remote sensing technology and we also do the terrestrial monitoring that we measure from the field and also mapping the mangrove and so we know how the dynamical of the mangrove in Indonesia. The FIO Surfei using remote sensing really helps us to monitoring the dynamical of the mangrove and also to monitor the area they have potential for mangrove so we can mapping the area for potential mangrove and also we can comparable with our national data and so improve our validation of the data. We have successfully restoration mangrove in Indonesia, for example in Kalimantan. We know the result is the ecosystem of mangrove is back for example for spawning fish and also the monkey is back and also we have the crocodile and also live in the mangrove ecosystem.
