Height-diameter allometry of tropical forest trees
Tropical tree height-diameter (H:D) relationships may vary by forest type and region making large-scale estimates of above-ground biomass subject to bias if they ignore these differences in stem allometry. We have therefore developed a new global tropical forest database consisting of 39 955...

Tropical tree height-diameter (<i>H:D</i>) relationships may vary by forest type and region making large-scale estimates of above-ground biomass subject to bias if they ignore these differences in stem allometry. We have therefore developed a new global tropical forest database consisting of 39 955 concurrent <i>H</i> and <i>D</i> measurements encompassing 283 sites in 22 tropical countries. Utilising this database, our objectives were: <br><br> 1. to determine if <i>H:D</i> relationships differ by geographic region and forest type (wet to dry forests, including zones of tension where forest and savanna overlap). <br><br> 2. to ascertain if the <i>H:D</i> relationship is modulated by climate and/or forest structural characteristics (e.g. stand-level basal area, <i>A</i>). <br><br> 3. to develop <i>H:D</i> allometric equations and evaluate biases to reduce error in future local-to-global estimates of tropical forest biomass. <br><br> Annual precipitation coefficient of variation (<i>P</i>V), dry season length (<i>S</i>D), and mean annual air temperature (<i>T</i>A) emerged as key drivers of variation in <i>H:D</i> relationships at the pantropical and region scales. Vegetation structure also played a role with trees in forests of a high <i>A</i> being, on average, taller at any given <i>D</ i>. After the effects of environment and forest structure are taken into account, two main regional groups can be identified. Forests in Asia, Africa and the Guyana Shield all have, on average, similar <i>H:D</i> relationships, but with trees in the forests of much of the Amazon Basin and tropical Australia typically being shorter at any given <i>D</i> than their counterparts elsewhere.
