1. Organizations and individuals
engaged in the management of forests and forest land shall implement this
Circular.
2. This Circular applies to all
forest areas, including consolidated forests and scattered forest trees
nationwide.
Chapter II
CRITERIA FOR FOREST IDENTIFICATION AND CLASSIFICATION
Article 3. Criteria for
forest identification
An area will be identified as a
forest if it meets all the following 3 criteria:
1. Being an ecosystem of which
the major component is perennial timber trees, bamboos and palms of all kinds
of a height of at least 5 meters (except new forest plantations which comply
with separate regulations below and some species of coastal submerged forest
trees and bamboos with a height of less than 5 meters at maturity), and capable
of providing timber and non-timber forest products and bringing about other
direct and indirect values such as biodiversity conservation, environmental
protection and landscape.
New forest plantations of timber
trees and newly regenerated forests after exploitation of forest plantations
will be identified as forests if they reach the average height of over 1.5
meters for slow-growing trees (for example, pine trees and some indigenous
trees) and over 3 meters for fast-growing trees (such as wattle and eucalyptus)
and a density of at least 1,000 trees per hectare.
Agricultural and aquacultural
ecosystems with scattered perennial timber trees, bamboos or palms will not be
regarded as forests.

3. Having forest plots of at
least 0.5 hectare each or forest tree strips of at least 20 meters in width and
be composed of at least 3 tree lines.
Consolidated forest trees on
areas of less than 0.5 hectare and forest strips of less than 20 meters in
width are called scattered trees.
Article 4. Classification of
forests based on use purposes

forests used mainly for protection of water sources and soil, prevention of
erosion and desertification, restriction of natural disasters, climate
regulation and environmental protection.
2. Special-use forests are
forests used mainly for nature conservation, preservation of standard specimens
of the national ecosystems and forest biological gene sources; scientific
research; protection of historical and cultural relics and landscape
preservation for recreation and tourism purposes in combination with
environmental protection.
3. Production forests are
forests used mainly for production and sale of timber and non-timber forest
products in combination with environmental protection.
Article 5. Classification of
forests based on
1. Natural forests are forests
which exist in the nature or are restored through natural regeneration,
including:
a/ Primary forests, which are
forests not yet or less influenced by humans or natural disasters and having a

- Restored forests, which are
forests formed through natural regeneration on land areas already deforested
due to milpa cultivation, forest fires or exhaustive exploitation;
- Post-exploitation forests,
which are forests undergone exploitation of timber or other forest products
2. Forest plantations are
forests formed through plantation, including:
a/ Forest plantations on land
without forests;
b/ Forest plantations on lands

c/ Forests naturally regenerated
after exploitation of forest plantations.
Based on growth time, forest
plantations are classified according to age levels. Depending on each tree
species, the time period prescribed for each age level may vary.

region.
c/ Freshwater-submerged forests,
which are forests growing on areas regularly or periodically flooded with
freshwater.
4. Dune forests are forests
growing on sand dunes or sand banks.
Article 7. Classification of
