Project in Thailand

A project in Thailand which is using mycorrhizas for growing native trees

Background

In facing the land degradation in Thailand, using local mycorrhizas can greatly speed up reforestation by enhancing the growth rate of native trees. Also, inoculating with some ectomycorrihizae when we plant the native trees especially at the seedling stage, the land could produce valuable edible mushrooms for community’s consumption after 2 to 3 years. For example, if we plant Yang Na seedlings that are inoculated with edible mycorrhizal fungi, we and our generations could harvest these mushrooms continuously.

Project Objectives

The goal of this project is to carry out community-based reforestation/restoration in deforested or plantation areas in Thailand. The work involves:

  1. To identifying local mycorrhizas for native tree planting;
  2. To set up a community based demonstration site for planting indigenous trees with these fungi;
  3. To conduct community training workshops to train villagers in identifying and managing mycorrhizas, native tree nursery management and tree planting practices. The demonstration plot will be established using a participatory approach. Community members and members of tree nurseries in this area will be recruited to plant and manage trees by using mycorrhizas in a deforested portion of the forest or a plantation area in Thailand;
  4. To increase the ability of carbon sequestration of the reforestation lands.

Project Highlights

Mycorrhizal fungi associated with plant roots increase the absorption of nutrients, particularly phosphorus, and thus enhance the growth of trees. By this reason, the technology to use mycorrhizal fungi is a noval and effective method in reforestation. We have finally identified 10 project sites for 4 regions. In these sites we choose native tree species Anisoptera costata, Shorea roxburghii, Dipterocarpus obtusifolius, Dipterocarpus alatus and Hopea odorata. We have already prepared a large number of seedling inoculated with EcM for experiments to establish the most effective operative method for our project. The seedlings was planted for reforestation in the lands which are ready. Besides, aftercare activities are also being prepared for the anticipated severe drought in dry season.

One of the collaborator NSRF have set up a website and Facebook to educate people and promote the project. The website is now on the developing process (a demo version: http://nsrf.smartsult.com/) and will be published soon. For carbon sequestration, we collect the baseline trees data in project sites and measure the total carbon content in soil in every year in order to find out the positive effect of the reforestation process in carbon sequestration.

To develop biodegradable pots for seedlings. Workshops from the university teams have been conducted including eco-pot workshop by Ubon Ratchathani University on February 10, 2019. The pots have been experimented with different formulas mainly using mushroom sawdust, dry cow dung, and rice starch glue. Another natural seedling container was experimented by NSRF using coir fiber, coir dust and natural glue. After testing durability and assessing cost-effectiveness, NSRF natural pot formula is selected and ready to be used for the project.
