a) Forests newly planted on non-forest land;

b) Replanted forests;

c) Forests naturally regenerated from planted forests after exploitation.

Article 5. Classification of forests by geological formation conditions

1. Earth mountain forests, including forests growing on earth hills and mountains.

2. Rocky mountain forests, including forests growing on rocky mountains or rock-revealing areas without or with less soil on the surface thereof.

3. Regularly or periodically flooded forests, including:

a) Saline-submerged forests, including those growing along marine shorelines and estuaries which are swamped by tidal saline water on a regular or periodic basis;

b) Alkaline forests, including forest areas growing on alkaline and brackish-flooded land;

c) Regularly or periodically freshwater-flooded forests.

3. Timber – bamboo mixed forests and bamboo – timber mixed forests.

4. Palm forests.

Article 7. Classification of forests by stock or volume

1. Timber forests are classified into the followings:

a) Rich forests with the standing stock of greater than 200 m³/ha;

b) Average forests with the standing stock ranging from greater than 100 to 200 m³/ha;

c) Poor forests with the standing stock ranging from greater than 50 to 100 m3/ha;

d) Extremely poor forests with the standing stock ranging from 10 to 50 m3/ha;

dd) Non-stock forests with the standing stock of less than 10 m³/ha.

2. Bamboo forests are classified by tree species, diameter class and density class; detailed classification shall be subject to regulations laid down in the Appendix I hereto.

Article 8. Non-forest areas

1. Areas where regenerating timber trees are under protected cultivation and restoration to be turned into forest areas.

2. Areas which are cultivated with forest plants but fail to satisfy criteria for being qualified as forests.

3. Areas currently in use for forest protection and development purposes.
