Tropical Rainforest Plot Network: Rainforest Tree Demographic Data, Northern Queensland, Australia, 2015

The 2015 LTERN Tropical Rainforest Plot Network Rainforest Tree Demographic Data contains stem measurement data from 7 of its 20, 0.5 ha (100 m x 50 m) permanent rainforest plots in Northern Queensland, Australia. This is part of a much larger dataset that spans from 1971 to 2015 managed by CSIRO. The CSIRO permanent rainforest plots are located within 60 km of the north Queensland coast between Mackay (21.5ºS, 149ºE) and the Iron Range on Cape York Peninsula (12.5ºS, 143ºE). The plots have a rainfall range of 1200 to 3500 mm, represent eleven vegetation types, six parent materials, and range from 15 m 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 is recorded. 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. The data collected from these 7 plots provides an insight into the floristical composition, structure and long term forest dynamics of Australian tropical rainforests and allows direct comparisons to be made with long-term monitoring plots at a global scale (Bradford, M.G., Murphy, H.T., Ford, A.J., Hogan, D. and Metcalfe, D.J.

2015年LTERN热带雨林样地网络（LTERN Tropical Rainforest Plot Network）热带雨林树木种群动态数据集，包含澳大利亚昆士兰州北部7个0.5公顷（100米×50米）永久性热带雨林样地的茎干测量数据，该网络共设20个此类样地。本数据集为CSIRO管理的1971年至2015年大型数据集的组成部分。CSIRO永久性热带雨林样地分布于昆士兰州北部海岸60公里范围内，涵盖从麦凯（21.5°S，149°E）至约克角半岛铁格伦（12.5°S，143°E）的区域。样地年降雨量范围为1200至3500毫米，涵盖11种植被类型与6种母质类型，海拔跨度为15米至1200米。除两处样地存在选择性采伐引发的轻微干扰外，所有样地均设立于原始老龄林内，且自此之后均受到保护。样地均定期开展普查，每次普查均记录所有胸径（DBH，diameter at breast height）≥10厘米的茎干数据。由于样地地理分布范围较广，未出现单一优势物种，但樟科（Lauraceae）、芸香科（Rutaceae）和桃金娘科（Myrtaceae）包含大量物种。从这7个样地收集的数据，有助于深入解析澳大利亚热带雨林的植物区系组成、群落结构及长期森林动态，并可与全球范围内的长期监测样地开展直接对比（参考文献：Bradford, M.G.、Murphy, H.T.、Ford, A.J.、Hogan, D. 及 Metcalfe, D.J.
