CHAPTER 1: INTRODUCTION
Plant conservation is one of the most important issues of concern to the world. The flora
is of the highest importance because of the habitat of living organisms. The survival and
development of plants are the basis for the evolution and evolution of the organism. Moreover,
plants contribute greatly to the healing of human disease from its use.
Vietnam is a tropical country, has the rich of vegetation cover with a variety of
medicinal plants. This precious herb resource contributes significantly to the initial health care
in our country, particularly to rural and mountainous communities. We have 54 ethnic groups
live together, each groups has their own traditional culture and experience in heathy care.
Medicinal plants in Vietnam are largely used empirically in each ethnic community.
Uniqueness in the use of medicinal plants have shown in the experience of the individual or
ethnic community. This valuable experience which has helped to build up the back group of
traditional medicine with a history of thousands of years.
However, the research, development, conservation and use of medicinal plants in
Vietnam is facing many challenges, such as many medicinal plants are exhausted and in danger
of extinction due to overexploitation. People in mountainous areas still have the habit of
exploiting available medicinal plants from natural forests. Moreover, they sell to male traders,
which leads to the danger of exhausting this resource quickly, and some high value species can
become extinct.
Xuan Son National Park in Tan Son district, Phu Tho province is considered as a region
with high biodiversity, which is the storehouse of gene sources of rare and precious plants and
animals of our country. There are 2,908 households in the national park, mainly Muong ethnic
(80%) and Dao ethnic (18%). The people still retain many traditional customs and tradition
characteristics in production as well as living and daily life. In particular, the use of medicinal
plants has been passed down through generations with many different remedies. But, in recent
times, the loss of many medicinal remedies, affecting indigenous knowledge in the use of
1
plants, medicinal herbs. In order to understand the status of conservation, exploitation and
provide the basis for proposing solutions to management of previous medicinal plants in the
study area, I do the topic: “Conservation and development of medicinal plant in Xuan Son
National Park, Phu Tho Province”.

The survey results show that:
- Forest cover accounts for 94%, in which the natural forest area accounts for 91% of
the forest cover and the remaining 3% of the forest area.
- Land without forests accounts for 6% of the total land area, including agricultural and
forestry land (non-agricultural land) and bare land (3.4 ha).
This shows that forest protection in the commune is very good. In the area, trees were
planted on the bare land.
3.2.2. Vegetation, animals and distribution of rare species
3.2.2.1. Ecosystems
- Evergreen forest with wet tropical rain : Distributed into relatively large patches below
700m in the south of Xuan Son Commune. Forest vegetation is quite rich, common in the family
: Dipterocarpaceae, Sapindaceae, Mimosaceae, Caesalpiniaceae....
- Evergreen forest with subtropical rain: Distributed in Ten mountain , Voi mountain
and a part of Xuan Son commune from 700 meters lattitude. The main plant species are the
broad-leaved trees of the family: Fagaceae, Lauraceae, Magnoliaceae, Aceraceae, Theraceae,
Sapotaceae...
11
- Tropical evergreen forest on limestone: Distribution concentrated in Can mountain,
typical species include: Excentrodendron tonkinense, Garcinia fagraeoides, guava, Streblus
spp., Chukrasia tabularis, Pometia pinnata ...
- Sub-tropical evergreen forest on limestone: Distributed into relatively large patches in
Can mountain from elevation 700m. Some coniferous species such as Amentotaxus argotaenia,
Podocarpus neriifolius and the rise of subtropical plants
- Secondary forest recovery after cultivation: Distributed scattered in the commune. The
species is represented such as: Trema oriantalis, Euvodia meliaefolia, Choerospondias
axillaries, Litsea cubeba, Shorea chinensis...
- Secondary forest: The bamboo forest occupies only a small area (56 hectares) in the
East of the Commune. Mainly Schizostachyum with small leaves, some species of wood trees
scattered. This type of forest is of poor economic value, but in terms of less fertile forest land
and high levels of illumination, bamboo forests has a major role in soil retention and erosion
control and create habitat conditions for some groups of wildlife.
- Plantation forest: distributed mainly in the lowlands located in the East and South of
the Commune. The restoration can be planted with indigenous species such as: Parashorea
chinensis H. Wang, Fibraurea tinctoria Lour., Dipterocarpus retusus Blume, Chukrasia
tabularis A. Juss.,....
- Grasslands, shrubs: scattered throughout the area, but most concentrated in the tropical
forests of the East of the commune. The ability to restore natural forests on land without forests
requires a long time.
- Cultivation, fields and residential: Scattered throughout the commune, but
concentrated into a large area in the East of the commune, where many villages, including paddy
rice fields, crops....

3.4. Situation of socio-economic development
3.4.1. Crop
- The main agricultural products are rice (50 hectares), potato, cassava, some products
for breeding (28.8 hectares). In addition, most of the irrigation water depends on natural
conditions, so the dry season is often lack of water, the area of rice is low, mainly cultivated
one crop.
- The area of sweet potato, cassava cultivated in the hillside, where the land is less
sloping and completely dependent on natural conditions, so productivity and output are not
high.
- Other crops: corn, beans, peanuts... are grown on high, flat land that is not suitable for
fields.

The survey results show, on the 4 transect lines in the National park, there are 182
medicinal plants belonging to 80 plant families, the variety of medicinal plants (182 species),
plant diversity (80 families), varied life forms (herbaceous plants, woody plants, vines), value
diversity (medicine, ornamental plants ...)
4.1.2. The status of using medicinal plant resources
The results of interviews with 60 villagers / 4 hamlets in the commune showed that 45
people knew how to use forest medicine (75%), 5 people knew the distribution of forest trees
and did not know how to use it, 10 people do not know how to use and do not know where to
distribute (17%).
4.1.3. The variety of parts used
The study of the components used to effectively source materials and orientation
when analyzing the chemical composition as well as its pharmacy. According to traditional
medicine experience in the use of medicinal plants, different parts of plants are used for
different purposes. On the other hand, the same part of the plant also has different effects but
depends on the way the physician uses it. We have listed the parts of medicinal plants used by
ethnic minorities for medical treatment. The results are shown in the following table:
