Background:

kesiya forest is the component of Vietnam montane forest which stands out in Asia for their richness of conifer species (Sterling et al 2006). It dominated in dry montane area in southern Vietnam and acted as main vegetation of evergreen coniferous in Da Lat Plateau. Together, the wide spread P. kesiya, the Indochina endemic pine P. dalatensis, Da Lat Plateau endemic pine P. krempfii and the mainland Southeast Asian pine P. latteri covered a narrow area of the most interesting nest of pine in the world limited by Bi Doup Nui Ba National Park, Phuoc Binh National Park and Chu Yang Sin National Park.

Most of studies about ectomycorrhizas of P. kesiya focused on some limited target fungal species in forest and not included the succession of ectomycorrhizal fungi with sporocarps. Understanding the ECM fungal communities attached with P. kesiya in several stage of forest will give the full image of the sustainability of pine’s forest.

Until now, almost cultivated area of P. kesiya in Vietnam were planted by seedlings. Many trials about directly germinating were not success with less than 30% area can be cover after 3 years (From the records of Da Nhim Watershed Protection Forest). It should be caused by the lack of ECM germs in the new planting area. Understanding clearly the role of ECM community in primary success of P. kesiya will contribute to the approach of directly germinating pine seeds in field and can cut off the cost in nursery as well as the pollution of nylon bags using for seedlings.

 

Our project highlight:

This study is the first study about ectomycorrhizal fungal communities of cultivated pine forests in Southeast Asia. An original idea of this study is using the ECM fungal communities to understand the succession of cultivated pines forest. Another original idea is using data of ECM fungal communities to understand the primary succession of pines and apply in sustainability reforestation.

Also, this project will set up the model for reforestation of P. kesiya forest for local communities from setting up the reforestation to income generating without destroying nature from their land.  We will work together with the communities, officers and related groups to develop a community-based ecotourism project.  It is a very important economic incentive for the communities to protect the forest sustainably.

The carbon accumulation will be investigated by exchanging the volume of wood by previous research model (Vien & Ton 2010). The project sites will be monitored and calculated the carbon accumulation using the previous model.  The proceed is adapted to the international standard of carbon measurement. The data will be used to evaluate the growth of pine and impact of the project.

 

Demonstration sites:

Two Demonstration sites will be conducted in southern Vietnam.  Those areas are near the famous tourist attraction located near Da Lat.  One is the land near the nature forest in Da Nhim Watershed Protection Forest (2 has shown in Fig 1) and another one is the degraded forest of Tay Nguyen Institute of Scientific Research (1 hectare spare land out of 10 hectares degraded forest), Lam Dong Province (Fig.2 ,3), Vietnam.  The forest of Tay Nguyen Institute of Scientific Research was damaged by forest fire in 2015 and in the recover stage.

The land in in Da Nhim Watershed Protection Forest is more bared and could be destroyed by human activities. In both sites, the land is not bared and scatteredly cover by natural seedlings of P. kesiya. All seedlings of P. kesiya will be kept as natural.
