Biological Surveys of South Australia, Vegetation Surveys

The Biological Databases of South Australia (BDBSA) is South Australia's flora and fauna database that stores and manages specimen and observation records. This record is a subset, focusing on the methodology known as the 'Biological Survey of South Australia Vegetation Surveys' and forms an important component of the BDBSA. This dataset includes vegetation structural attributes, observations on individual plants such as stem diameter, growth form, plant height, and plant community measures such as crown density, canopy cover, as well as plant occurrence data. Preliminary data associated with site description that include soil and landform related parameters are also included in this record. The resulting dataset provides a comprehensive record of plant diversity across sites ground-truthed during a diverse range of biological survey projects undertaken in South Australia and provides a basis for future updating of mapping or other relevant work such as species modelling.

Only validated BDBSA data is made publicly available and all records of sensitive taxa have been masked from the dataset. Data is accessible from the TERN Data Infrastructure, which provides the ability to extract subsets of vegetation data across multiple data collections and bioregions for more than 31 variables including stem diameter, tree crown extent, and number of individual plants.

南澳大利亚生物数据库（Biological Databases of South Australia, BDBSA）是南澳本土的动植物数据库，用于存储和管理标本与观测记录。本数据集为其子集，聚焦于名为“南澳大利亚生物调查之植被调查（Biological Survey of South Australia Vegetation Surveys）”的方法体系，是BDBSA的重要组成部分。本数据集涵盖植被结构属性、单株植物观测数据（如茎直径、生长型、株高）、植物群落指标（如冠层密度、郁闭度）以及植物出现数据。本记录还包含与样地描述相关的前期数据，涵盖土壤与地形相关参数。本数据集完整记录了南澳大利亚各类生物调查项目中经实地验证的样地植物多样性情况，可为后续的地图更新或物种建模等相关工作提供基础支撑。仅经过验证的BDBSA数据可对外公开，数据集已对所有敏感类群的记录进行了脱敏处理。数据可通过TERN数据基础设施（TERN Data Infrastructure）获取，该平台支持从多数据集集合与生物区中提取植被数据子集，涵盖茎直径、树冠范围、单株植物数量等超过31个变量。
