我们提供了1971年至2013年澳大利亚北方昆士兰州20个0.5公顷（100 × 50米）永久性雨林地块的重复树干测量数据。这些地块的降雨量范围为1200至3500毫米，代表11种植被类型，6种母质，海拔15至1200米。除了与两个地块上的选择性采伐有关的轻微干扰外，这些地块都是在古老的森林中建立的，此后所有地块都得到了保护。定期调查样地，每次调查时记录所有≥10 cm胸径的树干的胸径。数据为10 998个个体茎，建立时的地块茎密度范围为476至1104茎/公顷。由于地块的地理范围很广，没有物种占主导地位，尽管樟科，芸香科和桃金娘科贡献了大量的物种。建立时的断面积值范围为28.6至63.3平方米/公顷，并没有随着时间的推移而增加或减少的趋势，主要是由于定期干扰和自然事件（如旋风）的恢复。除了茎≥10厘米DBH数据，我们提出的高度数据，植物区系数据从林下茎（≥50厘米的高度，<10厘米DBH），辅助物种列表（包括藤蔓植物，附生植物，蕨类植物，草，草本植物，和其他生活形式），和凭证标本存放在标本库的列表。从20个地块收集的数据提供了深入了解澳大利亚热带雨林的植物区系，结构和长期森林动态，并允许在全球范围内与长期监测地块进行直接比较。
We present repeated stem measurement data from 20 0.5-ha (100 × 50 m) permanent rain forest plots in northern Queensland, Australia, from 1971 to 2013. The plots have a rainfall range of 1200 to 3500 mm, represent 11 vegetation types, six parent materials, and range from 15 to 1200 m above sea level. Except for minor disturbances associated with selective logging on two plots, the plots were established in old growth forest and all plots have thereafter been protected. Plots were regularly censused and at each census the diameter at breast height (DBH) of all stems ≥10 cm DBH were recorded. Data is presented for 10 998 individual stems with plot stem densities at establishment ranging from 476 to 1104 stems/ha. Due to the wide geographical range of the plots, no species dominate, although the families Lauraceae, Rutaceae, and Myrtaceae contribute a large number of species. Basal area values at establishment ranged from 28.6 to 63.3 m2/ha and showed no trend of increasing or decreasing over time due mainly to regular disturbance and recovery from natural events such as cyclones. In addition to stems ≥10 cm DBH data, we present height data, floristic data from understory stems (≥50 cm height to <10 cm DBH), an auxiliary species list (including vines, epiphytes, ferns, grasses, herbs, and other life forms), and a list of voucher specimens lodged in herbaria. The data collected from the 20 plots provides an insight into the floristics, structure, and long-term forest dynamics of Australian tropical rain forests and allows direct comparisons to be made with long-term monitoring plots at a global scale.
