Desert Ecology Plot Network: Vegetation Plot-data, Simpson Desert, Western Queensland, 2015

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 which are sampled every April-May. 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.

本植被数据包包含相关数据包中所述网格内选定点位的群落结构与植物区系数据。植被属性的调查区域为每个诱捕网格内6个诱捕器周边半径2.5米的范围，相关数据已聚合至网格尺度。本次记录了所有植物物种的盖度百分比、开花指数与结实指数（取值范围0-5，其中0代表无开花或结实，5代表开花/结实程度最高），并以样地平均值形式发布，该平均值代表各物种的平均开花或结实水平。本监测项目的核心布设12个固定样地，每年4至5月开展采样工作。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，这些驱动因子包括不可预测的降雨与干旱、火灾、野生捕食者以及放牧活动。作为沙漠生态完整监测计划一部分收集的相关数据包概要，可通过以下链接获取：http://www.ltern.org.au/index.php/ltern-plot-networks/desert-ecology。
