| Outline of Final Research Achievements |
Tree density and species of mangrove forests were investigated at the central Philippine islands, both at planted forests of Rhizophora stylosa and natural ones. It is elucidated that the nearly 100% was occupied by planted species at planted sites, compared to low percentage of natural forests. The tree density of planted forest deliberately decreased with average tree height by natural self-thinning and has regressed to 1000~2000 ind/ha at maximum after 50 years.
