Mixed species plantations: does diversity help tropical eucalypts grow faster, better, longer?

为了验证混合栽培优于单一栽培的假设，使用了来自实验（QFRI）和社区种植的数据。桉树（红桃花心木）的生长速度、习性（形态、分支）、木材和土壤特征应阐明混合物是否：

To test the assumption that mixtures are better than monocultures, using data from experiments (QFRI) and community plantings. Growth rate, habit (form, branching), timber and soil characteristics in Eucalyptus pellita (Red Mahogany) plantings should elucidate whether mixtures: 1. grow (above-ground woody biomass) faster than pure plantings; 2. have straighter trees with smaller branches; 3. improve soil fertility; and whether 4. differences are accentuated in subsequent rotations. E. pellita has valuable dark-red timber, and is widely planted in north Queensland, despite variable performance (3-30 m3/ha/yr, average 10m3/ha/yr). Analyses will reveal opportunities for conservation outcomes and sustainable timber production.
