Maximising productivity of Eucalyptus and Acacia plantations for growers in Indonesia and Vietnam

This project will help Indonesian and Vietnamese growers of short rotation Eucalypt and Acacia plantations to improve their productivity and profitability, and make growers aware of the benefits and limitations of eucalypts as replacement for acacias. Indonesian and Vietnamese smallholders and private sector growers have widely adopted Eucalypt and Acacia plantation technologies over the past 20 years, but now face threats from bacterial wilt and root rot diseases.
Acacias have been a plantation species of choice in both Indonesia and Vietnam, but diseases threaten this resource. Ceratocystis fungal stem wilt/canker disease is spreading rapidly and reducing the productivity of many plantings to a level where they are not commercially viable to harvest, especially in larger scale plantations in Sumatra and Kalimantan.
Eucalyptus pellita are replacing acacias over large areas of Sumatra and Kalimantan, as it grows reasonably quickly, and can be both pulped and sawed well. Eucalyptus pellita has two key drawbacks compared to acacias. Its growth rates are significantly lower than A.mangium with the same level of management inputs. Little is known about the factors that affect its performance across different site types; it grows poorly on some site types compared to Acacia. Understanding its productivity and increasing its profitability are needed to maximise returns to growers. This project aims to address these issues.
