Tropical acacias are of considerable social and industrial importance for tropical reforestation and it is expected that about 2 million hectares will be established in South East Asia by the year 2000. Reports from Malaysia, Indonesia, Thailand and northern Australia suggest that the future productivity of some of the important species may be prejudiced by fungal pathogens including leaf spots, shoot blights, stem cankers, heart rot, root rot and gall rusts. As part of the original study during 1995-96, a series of disease surveys of tropical acacias have been undertaken in native stands, trials operational and social forestry plantings in India, Malaysia, Thailand, Indonesia and Australia to assess the potential of fungal pathogens as limiting factors to tree growth and productivity and to assess the relative importance of individual fungal species.
Lead scientists from these countries met with research managers from Indonesian companies and government business enterprises from April 28 - May 3 1996 at Subanjeriji in Sumatra at the base camp of Musi Hutan Persada to present the results of the surveys. A publication on the status of acacia diseases in the several countries based on these reports will be the main output of the initial project. The preparation of this proceedings is well advanced and will be published by CIFOR early in 1997.
