1. MDF production: Global industry development and prospects in Vietnam

(Nguyen Manh Hoat)

Medium Density Fibre (MDF) board production technology was first launched 40 years ago, and with a very high growth of over 15% annually it now occupies an important place in the composite board market. In the future, MDF is expected to continue to be the preferred composite board since it is widely used for furniture production, in many different forms and dimensions. These qualities make it suitable for many different processing technologies and consumer demands. Vietnam is developing an efficient MDF production capacity which will assist in the future for taking initiatives for export furniture processing.


2. CDM — A new opportunity for the forestry sector

(Cao Lam Anh)

According to a Ministry of Agriculture and Rural Development Report in 2003, forestry made a contribution of about 5% to the total income of the agricultural sector. This figure is mostly the value obtained from exporting wood products. However less tangible or direct values generated by the forestry sector are also considerable, for example from tourism, conservation, biodiversity, soil and water protection, environmental protection, etc. In practice, these values have not been studied or quantified, and little attention has been paid to the forest’s environmental functions by the relevant agencies.


3. Assessment of some models of mixed plantation in Northern provinces

(Hoang Van Thang)

Assessment of the existing models of mixed plantation in Northern provinces has shown that due to a poor choice of tree species and afforestation spacing arrangements and other technical constraints most mixed afforestation models under Program 327 are not effective. Most of the main tree species under these models perform poorly and are being outgrown by understorey trees. However, on some categories of degenerated land, some models of mixed plantation with indigenous broad-leaf trees are successful. In order to successfully develop these models further, monitoring growth with timely measurement is essential.


4. Pure forest transformation and orientation for mixing with indigenous large-leaved trees in the afforestation project in Lang Son and Bac Giang

(Vu Van Hung)

The “Afforestation project in Lang Son and Bac Giang – KfW1” funded by the German Federation has been implemented since 1995. Until now, the stands of pure Pinus massoniana and A. mangium and A. auriculiformis have a closed canopy, especially the stands grown in 1997 and 1998 which are growing well. There is strong competition for nutrition between individuals; at the same time, micro-climates under the canopy in the forest have been improved since the start of the project and naturally regenerated trees have started to appear in some places under the new forest. In order to make this forest development sustainable, apart from techniques such as pruning, trimming and caring for the forests, studies are necessary for promoting natural regeneration under the forest and identifying suitable indigenous plants to grow under the forest canopy.


5. Status of non-timber forest products and their role in the social and economic life in Van Yen commune, Van Don district, Quang Ninh province

(Dang Thinh Trieu)

Dai Mo and Dai Lang are two villages with great potential for non-timber forest products in Van Yen commune, Van Don district, Quang Ninh province. Surveys show that there are up to 44 species of non-timber forest products of high value. However, because techniques for growing and exploitation are not available, many species of non-timber forest products have been exhausted through exploitation – with current reserves reduced by 50-80% from the levels of previous years. In order to restore and develop the non-timber forest products resources at this locality, it is necessary to carry out training and instruction for the local people on techniques for growing and exploiting these products. This is the basis for sustainable development of non-timber forest products at the locality.


6. Assessment of upstream protection forest quality in Ha Tinh

(Dang VanThuyet)

From survey and assessment of watershed quality for the 5 million hectare reforestation program in 1998-2004, prospective models and solutions for improving watershed quality for 2006-2010 are suggested.

Generally, afforestation models at 1-3 years can grow and develop well. However in some stands on steep slopes or in designs to meet local preferences, the quality of protection forest is not satisfactory or consistent with the regulations for the protection afforestation process. Thus, protection plantation quality should be reviewed in each specific case in terms of soil, species suitability and land use needs of the local people. In addition, investment for watershed should be appropriate to the actual situation in the field.


7. Effect of land and forest allocation on productive plantation development in some mountainous provinces of the North

(Vo Dai Hai)

The project has re-evaluated results of land and forest allocation and its effects on productive plantation development in mountainous provinces of the North. The research has taken place in three forestry ecological zones, Northwest, Central and Northeast; and direct, indirect interviewing and productive plantation surveys have been carried out in some mountainous provinces in the North.


8. Some obstacles to the exploitation of wood and other forest products (Decision No. 40/2000/QD-BNN, dated 7th July 2005)
