Desert Ecology Plot Network: Vegetation Plot-data, Simpson Desert, Western Queensland, 1990–2011

This vegetation data package comprises structure and floristic data for selected points across grids described in related data packages. Vegetation attributes were recorded in an area occupying 2.5 m radius around six traps on each trapping grid and have been aggregated to grid level data. Percentage cover of all plant species, flowering index and seeding index (from 0-5, where 0 is no flowering or seeding and 5 is maximal flowering/seeding) were recorded and are presented here as plot averages which represent the mean amount of flowering or seeding per species. The network program uses a core of 12 sites. The trapping survey aims to quantitatively track long-term shifts in biodiversity and ecological processes in relation to key drivers, including unpredictable rainfall and droughts, fire, feral predators and grazing. A synopsis of related data packages which have been collected as part of the Desert Ecology's full program is provided at http://www.ltern.org.au/index.php/ltern-plot-networks/desert-ecology.

本植被数据集包含相关数据集中所述网格内选定样点的群落结构与植物区系组成数据。植被属性的调查范围为每个诱捕网格内6个诱捕器周边2.5米半径的区域，相关调查数据已聚合至网格尺度。本数据集记录了所有植物物种的盖度百分比、开花指数与结实指数（取值区间为0至5，其中0代表无开花或结实现象，5代表开花/结实程度达到最高水平），并以样地平均值形式呈现，该平均值为各物种的平均开花或结实强度。本监测网络以12个样地作为核心监测站点。本次诱捕调查旨在定量追踪生物多样性与生态过程的长期动态变化，及其与关键驱动因子的关联，这些驱动因子包括无规律降雨与干旱、火灾、野生捕食者以及放牧活动。作为沙漠生态学完整项目组成部分所采集的相关数据集概要，可通过以下链接获取：http://www.ltern.org.au/index.php/ltern-plot-networks/desert-ecology。
