Management strategies for Acacia plantation diseases in Indonesia and Vietnam;

The project aims to reduce the effects of diseases that limit productivity of Acacia plantations and build capacity and collaboration on forest health in Indonesia, Vietnam and neighbouring Southeast Asian countries.
Plantation forests of Australian hardwood species in Southeast Asia now exceed 7 million hectares. Diseases and pests threaten the viability of these plantations. Due to tree mortality, growth rates of Acacia mangium in Sumatra in those areas affected by fungal diseases (Ganoderma and Ceratocystis) have been reduced to less than 15 m3/ha/yr, while non-affected areas grow 22 to 35 m3/ha/yr. Ceratocystis is considered an extreme threat in both Vietnam and Malaysia, with up to 20% damage in some Vietnamese acacia plantations.
The research includes aspects of forest silviculture, genetics, biological disease control, forest health surveillance, information technology and extension. Screening for tolerant acacia germplasm and developing biocontrol agents will reduce mortality of acacias caused by Ceratocystis and Ganoderma. Diseases may influence the success of management strategies, so research into these diseases will support the activities.
