Why there are issues & opportunities in mangrove
rehabilitation
Do we know enough about
mangrove ecosystem
Do we have enough information
about mangrove being
published, disseminated and
circulated to the general public
Do the policy makers aware &
appreciate the value and
function of mangroves. If they
do why there is still a conflict in
land use resulting more
mangroves being excised
The perception of the general
public about the mangroves

Coastal Protection
Mangrove Rehabilitation
Successful rehabilitation
Not all areas can be rehabilitated. Naturally this area
is not ready to support vegetation
ISSUE vs OPPORTUNITY
A movement is restricted but can be
overcome
The problem creates opportunity

Awareness & education by appreciating the
nature
Enhance coastal protection through rehabilitation
But rehabilitation is not always successful
Conclusion
• Muddy is beautiful
but highly vulnerable
to destruction
• The habitat needs
protection
• Habitat restoration is
difficult
• Rehabilitation is
possible but may not
always be successful
