Victorian Tall Eucalypt Forest Plot Network: Vegetation Survey Data, Central Highlands of Victoria, Australia, 2012

The Victorian Tall Eucalypt Forest Plot Network Vegetation Survey Data contains transect, plot- and subplot-based vegetation data collected from 175 spread across the montane ash forests of the Central Highlands in Victoria, Australia. Vegetation related data is collected annually from 105 of 175 sites (mainly sites burnt in 2009) and every 2 to 3 years from the remaining 70 sites (unburnt sites). Vegetation species are recorded along transects. A Height versus Diameter matrix is used to record all woody plants and tree ferns over 2m in height within the three 10 x 10 m plots situated along the transect. A basal sweep is done in the middle of each 10 x 10 m plot. Basal Area Factor 1m squared is used with the number of Acacia species recorded, as well as whether the tree is alive or dead. Seedling plots (1mx1m) are located in the middle of each of the three 10mx10m plots and all living plant species which are less than 5 m in height with their bases rooted within the 1 x 1 m plots are recorded by height increments in the table. This is part of a much larger dataset that began in 1983, when the Victorian Tall Eucalypt Forest Plot Network research plots commenced.

维多利亚州高大桉树林样地网络植被调查数据，收录了采自澳大利亚维多利亚州中部高地山地灰林的175个样地的样带(transect)、样地(plot)及亚样地(subplot)尺度植被数据。175个样地中的105个（主要为2009年过火样地）每年开展一次植被调查，剩余70个未过火样地则每2至3年开展一次调查。

植被物种沿样带进行记录。沿样带设置的3个10×10米样地内，所有株高超过2米的木本植物与树蕨(tree ferns)，均通过高度-直径矩阵进行登记。在每个10×10米样地的中部开展基径扫测(basal sweep)，采用断面积系数(Basal Area Factor)为1平方米的方法，记录金合欢属(Acacia)物种的数量，以及树木的存活与死亡状态。在每个10×10米样地的中部设置1×1米的幼苗样方(seedling plots)，对所有株高小于5米、基部扎根于该1×1米样方内的活植物物种，按高度分级在表格中记录其相关信息。

本数据集是1983年启动的更大规模数据集的组成部分，当年维多利亚州高大桉树林样地网络的研究样地正式设立。作为该网络完整调查计划一部分采集的相关数据包概要，可通过以下链接查阅：http://www.ltern.org.au/index.php/ltern-plot-networks/victorian-tall-eucalypt-forest
