GENERAL PROVISIONS

Article 1. Scope of Regulation

This Circular regulates forestry measures, including:

2. Forest tending; forest enrichment;

3. Natural forest improvement;

4. New forest plantation; replanting forests; caring for and nurturing planted forests.

Article 2. Applicability

This Circular applies to organizations, households, individuals, and community residents involved in forestry measures as stipulated in Article 1 of this Circular.

1. Encirclement and nurturing to promote natural regeneration is a forestry measure that maximizes the natural regeneration and succession capabilities to restore forests through protective measures against cutting, fire prevention and firefighting, clearing vines and shrubs to promote forest formation within a specified period.

2. Encirclement and nurturing to promote natural regeneration with supplementary planting is a forestry measure that maximizes the natural regeneration and succession capabilities to restore forests through protective measures against cutting, fire prevention and firefighting, clearing vines and shrubs, combined with supplementary planting of a certain number of trees in areas lacking regenerating trees to promote forest formation within a specified period.

3. Forest tending is a forestry measure that adjusts density and species composition by removing non-purpose trees, low-quality trees, and nutrient-competing vines, retaining high-quality purpose trees to enhance productivity, quality, and value of the forest.

4. Forest enrichment is a forestry measure that combines forest tending with supplementary planting of a certain number of purpose trees while retaining existing purpose trees in the forest.

5. Natural forest improvement is a forestry measure that replaces depleted natural forests with planted forests having higher productivity, quality, and economic efficiency.

6. New forest plantation is a forestry measure that establishes forests for the first time on land without existing forests.

8. Caring for planted forests is a forestry measure that promotes better growth and development of forest trees through grass removal, soil cultivation, fertilization, and other activities.

9. Large timber planted forest is a forest where at least 70% of standing trees on a unit area have a diameter at breast height of 20 cm or more for fast-growing trees or 30 cm or more for slow-growing trees at the main harvesting age.

10. Small timber planted forest is a forest where less than 70% of standing trees have a diameter at breast height of 20 cm or more for fast-growing trees or 30 cm or more for slow-growing trees at the main harvesting age.

11. Conversion of small timber planted forest to large timber planted forest is the application of technical forest tending measures to change the business purpose from small timber production to large timber production.

12. Companion tree is a tree planted alongside the purpose tree for a certain period to promote better growth and development of the purpose tree.

13. Non-purpose tree is a tree that does not meet the forest usage purpose.

14. Purpose tree is a tree that meets the forest usage purpose.

17. Recovered forest is a forest formed by natural regeneration on land that has lost its forest due to shifting cultivation, forest fires, or over-exploitation.

18. Land without forest is land for planting or land with ground cover consisting of reeds, sedge, shrubs, scattered trees, bamboo, and regenerating trees but not meeting the criteria for a forest.

19. Regenerating tree is a naturally grown sapling from seeds or root sprouts of trees.
