The Native Vegetation of the Sydney Metropolitan Area - Version 3.1 (OEH, 2016) VIS_ID 4489

This layer contains digital mapping of the native vegetation communities of the Sydney Metropolitan area. Vegetation communities have been derived from the analysis of 2200 floristic sites collated for the study area. Identified vegetation communities have been related to currently listed threatened ecological communities listed under the NSW TSC Act, 1995 and the Commonwealth EPBC Act, 1999. Native vegetation communities have been mapped using a combination of detailed image interpretation, relationships between sample sites and abiotic environmental variables. The derived digital data layer includes fields that describe the vegetation community, interpreted dominant species and understorey characteristics, interpretation confidence, disturbance type and severity, NSW vegetation formation and classes and related NSW Plant Community Types. These are described in detail in technical reports OEH (2016) The Native Vegetation of the Sydney Metropolitan Area. Volume 1: Technical Report. Version 3.0. Office of Environment and Heritage Sydney. OEH (2016) The Native Vegetation of the Sydney Metropolitan Area. Volume 2: Vegetation Community Profiles. Version 3.0. NSW Office of Environment and Heritage, Sydney.\r\nVersion 3.0 of the Native Vegetation of the Sydney Metropolitan Area updates the Plant Community Type and Biometric Vegetation Type of each map unit. \r\n\r\nVersion 3.0 replaced version 2.0 (VIS_ID 3817) and created a seamless alignment between the GIS layer and the Plant Community and Biometric Vegetation Types in the Biodiversity Assessment Method tool. These were the only significant updates from version 2.0.\r\n\r\nVersion 3.1 is a minor update. Two new attribute fields were added - PCTID and PCTName. These fields align with the Bionet Vegetation map data standard v1.0(https://www.environment.nsw.gov.au/research-and-publications/publications-search/bionet-vegetation-map-data-standard-version-1). PCTID was populated by the v3.0 attribute field, PCT_code. PCTName was populated by extracting the corresponding PCT common name from the Bionet Vegetation Classification web service (https://data.bionet.nsw.gov.au/). No other changes were made to the vegetation map.\r\n\r\nVIS_ID 4489

本数据集图层包含悉尼都会区原生植物群落的数字化制图成果。本次研究区内整理的2200个植物区系样地的分析结果，为本数据集的植物群落划分提供了依据。本次识别出的植物群落，已与1995年《新南威尔士州濒危物种保护法》（TSC Act）及1999年《联邦环境保护与生物多样性保护法》（EPBC Act）中当前收录的濒危生态群落建立关联。原生植物群落的制图工作，综合运用了精细影像解译、样地与非生物环境变量间的关联关系等方法。生成的数字化数据图层包含多个属性字段，用于描述植物群落、解译得到的优势物种与林下层特征、解译置信度、干扰类型与强度、新南威尔士州植被群系及分类单元，以及相关的新南威尔士州植物群落类型。上述内容的详细说明可参见两份技术报告：OEH（2016）《悉尼都会区原生植被》第一卷：技术报告（3.0版），悉尼环境与遗产局；以及OEH（2016）《悉尼都会区原生植被》第二卷：植物群落概览（3.0版），新南威尔士州环境与遗产局，悉尼。

《悉尼都会区原生植被》3.0版更新了每个制图单元的植物群落类型与生物特征植被类型。

3.0版替代了2.0版（VIS_ID 3817），实现了地理信息系统（GIS）图层与生物多样性评估方法工具中的植物群落类型及生物特征植被类型的无缝匹配。上述两项为2.0版以来的核心更新内容。

3.1版为小幅更新，新增了两个属性字段：PCTID与PCTName。这两个字段符合《Bionet植被制图数据标准v1.0》（https://www.environment.nsw.gov.au/research-and-publications/publications-search/bionet-vegetation-map-data-standard-version-1）规范。其中PCTID取自3.0版的属性字段PCT_code，PCTName则通过Bionet植被分类网络服务（https://data.bionet.nsw.gov.au/）提取对应的植物群落类型通用名称获取。本次植被制图未进行其他修改。
