Upland Heath Swamps Plot Network: Plot Details - Spatial Coordinates, Dharawal National Park, Sydney Basin, NSW, Australia

This dataset contains spatial information for plots established in the Dharawal National Park. Sampling of soil is stratified along the soil moisture gradient and across the range of structural variability in the vegetation. Thus three categories of soil moisture and three categories of vegetation structure (based on the height and form of shrubs) are sampled in a factorial design at 60 sites in upland swamps scattered throughout the study area (Keith and Myerscough 1993). Each permanent swamp monitoring site consists of a belt transect of 30 contiguous 0.5x0.5 metre quadrats. Quadrats 1 and 30 are marked with steel star pickets, extending approximately 1.5 m above ground surface. This spatial data complements data collected from soil moisture, soil properties, vegetation and hydrological climate surveys conducted at these sites. A synopsis of related data packages which have been collected as part of the Upland Heath Swamps Plot Network’s full program is provided at http://www.ltern.org.au/index.php/ltern-plot-networks/upland-health-swamps.

本数据集包含达拉瓦尔国家公园（Dharawal National Park）内设立样地的空间信息。土壤采样沿土壤水分梯度分层开展，并覆盖植被结构的全部变异范围。因此本研究在遍布研究区域的高地沼泽60个样地中，采用析因设计（factorial design）对3类土壤水分等级与3类植被结构等级（基于灌木高度与形态）进行了采样（Keith与Myerscough，1993）。每个永久性沼泽监测样地由包含30个连续0.5×0.5米样方的带状样带构成。样方1与样方30处设有钢制星状桩，其地面以上延伸高度约1.5米。本空间数据集可补充在上述样地开展的土壤水分、土壤理化性质、植被与水文气候调查所获取的数据。作为高地石楠沼泽（Upland Heath Swamps）样地网络完整项目的一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/upland-health-swamps。
