Environmental and allometric drivers of tree growth rates in a north Australian savanna

Frequent fire is a feature of the mesic Australian savannas, yet little is known about its effect on tree growth rates. Growth data are critical for the development of demographic models to understand the consequences of different land management regimes. We used generalized linear mixed effects models and information-theoretic multi-model inference to analyse annual diameter growth of adult trees (≥5 cm diameter at breast height, DBH) and saplings (≥1.5 m height and
