SALINITY IMPACTS UPPER SOUTH EAST Survey, Biological Survey of South Australia - Vegetation Survey, Biological Database of South Australia

To investigate the effect of rising groundwater and salinity on the health of low-lying vegetatin in the Bunbury-Taunta area, 14 vegetation survey sites were conducted in 1992.Survey site methodology was the Biological Survey of SA, with quadrats generally being 30 x 30 m but some were 5 x 50 m. The study's objectives were to map and describe the different health classes and extent of vegetation degradation, describe the process and timing of vegetation decline, and predict future decline in vegetation health. At each site, species presence and abundance data was collected, samples of soil, groundwater and surface water were collected for salinity readings and a general description of the area was made. Photopoints were also established. The data was then analysed subjectively to determine the typical characteristics for each health class. The report resulting from the study is: Webb, L (1993), An investigation into the environmental effects of rising groundwater and salinity on native vegetation in the Bunbury-Taunata area (including the proposed Lesron Conservation Park) in the Upper South East of South Australia. The SALINITY IMPACTS UPPER SOUTH EAST Survey is part of the Biological Survey of South Australia Program which is a series of systematic surveys conducted across the state between 1971 and the present with the broad aim of providing a baseline inventory of South Australia's flora and fauna biodiversity.

为调查邦伯里-汤塔（Bunbury-Taunta）地区地下水位上升与盐度变化对低洼植被健康的影响，研究团队于1992年布设了14个植被调查样地。调查样地方法采用南澳大利亚生物调查法（Biological Survey of SA），样方（quadrats）规格一般为30×30米，部分样方为5×50米。本研究的目标为：绘制并描述不同植被退化健康等级与退化范围，阐明植被衰退的过程与时间节点，并预测植被健康的未来衰退趋势。在每个样地中，研究人员采集了物种存在度与多度数据，收集土壤、地下水与地表水样本以测定盐度，并对调查区域进行综合描述；同时建立了定点摄影监测点（Photopoints）。随后通过主观分析确定各健康等级的典型特征。本研究形成的最终报告为：Webb, L (1993), 《南澳大利亚东南部上区邦伯里-汤塔塔（Bunbury-Taunata）地区（含拟建莱斯伦保护区）地下水位上升与盐度对本土植被的环境影响调查》。本数据集所属的"南澳东南部盐度影响调查"（SALINITY IMPACTS UPPER SOUTH EAST Survey）是南澳大利亚生物调查计划（Biological Survey of South Australia Program）的组成部分，该计划自1971年起在全州范围内开展系统性调查，其核心目标是建立南澳大利亚动植物生物多样性的基线名录。可通过以下链接获取本数据集：http://aekos.org.au/collection/sa.gov.au/bdbsa_veg/survey_1082
