Tropical Rainforest Plot Network: Rainforest Tree Demographic Data (Plot EP40), Northern Queensland, Australia, 2011-2013

The LTERN Tropical Rainforest Plot Network Rainforest Tree Demographic Data contains stem measurement data for 1 of 20, 0.5 ha (100 m x 50 m) permanent rainforest plots in Northern Queensland, Australia from 2011 to 2013.

This is part of a much larger dataset that spans from 1971 to 2013 that is managed by CSIRO. This data publication refers specifically to observations made at Plot EP40, and this data is accessible as a composite data package at the following location:

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 the 20 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. (2014). Long term stem inventory data from tropical rainforest plots in Australia. Ecology 95:2362. http://www.rainforest-crc.jcu.edu.au/publications/permanent_plots1.pdf. This is part of a much larger dataset that spans from 2004 to 2014; a synopsis of related data packages which have been collected as part of the Tropical Rainforest Plot Network’s full program is provided at http://www.ltern.org.au/index.php/ltern-plot-networks/tropical-rainforest.

LTERN热带雨林样地网络雨林树木种群动态数据集，包含澳大利亚昆士兰州北部20块0.5公顷（100米×50米）永久热带雨林样地中1块样地2011年至2013年的茎干测量数据。

本数据集隶属于一套时间跨度为1971年至2013年的更大规模数据集，由澳大利亚联邦科学与工业研究组织（CSIRO）管理。本次发布的数据特指EP40样地的观测结果，可通过以下链接获取组合式数据包：

澳大利亚联邦科学与工业研究组织（CSIRO）的永久热带雨林样地分布于昆士兰州北部沿海60公里范围内，覆盖从麦凯（21.5°S，149°E）至约克角半岛铁岭（12.5°S，143°E）的区域。样地年降雨量介于1200至3500毫米之间，涵盖11种植被类型、6种母质类型，海拔跨度为15米至1200米。除两块样地存在选择性采伐带来的轻微扰动外，所有样地均设立于原始老龄林内，并在此后得到严格保护。样地定期开展普查，每次普查均记录所有胸径（diameter at breast height，DBH）≥10厘米的茎干的胸径。由于样地地理分布范围广泛，无绝对优势物种，但樟科（Lauraceae）、芸香科（Rutaceae）和桃金娘科（Myrtaceae）包含的物种数量较多。

基于20块样地收集的数据，可深入解析澳大利亚热带雨林的区系组成、群落结构与长期森林动态，并可与全球范围内的长期监测样地开展直接对比（Bradford, M.G., Murphy, H.T., Ford, A.J., Hogan, D. and Metcalfe, D.J. (2014). 澳大利亚热带雨林样地长期茎干清查数据. 《生态学》95:2362. http://www.rainforest-crc.jcu.edu.au/publications/permanent_plots1.pdf）。
