Vegetation Demographic Cover and Floristic Data, Great Western Woodlands SuperSite, 2012-2013

Tree demographic, tree biomass and shrub count data for two Ausplots adjacent to Credo Flux tower (Salmon Gum, SG100E and Gimlet, Gim100W). Floristic survey data and 1000 points of cover. Tree demographics was measured using a tape at 130cm for diameter and 2 different laser height finders. These gave consistently different measures and both are presented. Plot biomass was calculated from allometric regression published by Jonson and Freudenberger (2011). All shrubs with mature heights of over 0.5m were measured in ten, 10m wide by 100m transects to ensure all shrubs in the one hectare plots were counted. Floristic survey was undertaken and 1000 point intercepts recorded along 10 lines (5 north-south, 5 east-west with one point per meter) for SG100W according to Ausplots methodology (Foulkes et al., 2011)

本数据集包含毗邻克雷多通量塔（Credo Flux tower）的2个澳大利亚样地计划（Ausplots）样地的树木种群统计、树木生物量及灌木数量数据，涉及银叶桉（Salmon Gum）样地SG100E与吉木桉（Gimlet）样地Gim100W。数据集涵盖植物区系调查数据与1000个覆盖度样点数据。树木种群统计指标的测定方式为：使用卷尺测量130cm处的胸径，采用2台不同型号的激光测高仪测定树高；两类仪器的测量结果存在稳定的系统性差异，故两种数据均予以收录。样地生物量通过Jonson与Freudenberger于2011年发表的异速生长回归模型计算得出。针对所有成熟株高超过0.5米的灌木，在10条宽10米、长100米的样带内开展调查，以确保1公顷样地内的所有灌木均被统计在内。依据澳大利亚样地计划（Ausplots）的方法（Foulkes等，2011），针对SG100W样地开展了植物区系调查，并沿10条样线（5条南北向、5条东西向，每米设置1个样点）记录了1000个样点的植被截获数据。
