REHABILITATION THROUGH
REFORESTATION IN THE PHILIPPINES
The objective of Reforestation in the
Philippines is to revitalize marginal and degraded public areas.
 It employs replanting, natural regeneration, direct seeding, and various combination of these techniques.
 Many organizations undertook different programs and participated in government reforestation projects, either on a voluntary or compulsary basis.

The Philippine forestry statistics of 19881992 revealed that the tree species used in reforestation were mostly exotic species.
