Assessing invasive alien species pressures on biodiversity in New South Wales (impact dimension): Data packages for the Biodiversity Indicator Program, first assessment

This data collection contains the data inputs, analytical processes and derived outputs including indicator metrics for the first assessment of the impact dimension of the invasive species (pests, weeds, disease) indicator in the New South Wales Biodiversity Indicator Program. If the same workflows and metrics implemented in this first assessment are repeated in future assessments, this will enable change detection over a five-year timescale.\n\nDetails on indicator design, implementation methods and findings from the first assessment are provided in a technical implementation report: Froese JG, Gooden B, Hulthen AD, Ponce-Reyes R, Burley AL, Cherry H, Hamilton M, Nipperess DA, Russell B, West P & Williams KJ (2021), Assessing invasive alien species pressures on biodiversity in New South Wales, Biodiversity Indicator Program Implementation Report, Department of Planning, Industry and Environment NSW, Sydney, Australia.\n\nThe key results and highlights of the first assessment are presented in a supplement report card: DPIE (2021), Report card: Invasive species, Supplement to the NSW Biodiversity Outlook Report, Department of Planning, Industry and Environment, Sydney, Australia.\nLineage: The indicator reports on two linked but separately measured dimensions by which invasive alien species (IAS) pressures on native biodiversity and ecosystem quality in New South Wales can be quantified: (i) exposure, which refers to the presence, size and extent of IAS pressures on native biodiversity and ecosystem quality; (ii) impact, which refers to the detrimental consequences of IAS pressures to native species and ecological communities. In the first assessment, several metrics were implemented to quantify exposure and impact from data and knowledge sources that were readily available and accessible at the time of implementation. \n\nRelevant explanatory notes for the invasive alien species impact dimension were extracted from the technical implementation report and attached to this data package. These explanatory notes comprise (i) a brief summary of the indicator design and implementation methods, and (ii) a technical workflow diagram and description of data inputs, analytical processes and derived outputs including indicator metrics.

本数据集涵盖新南威尔士州生物多样性指标计划中入侵物种（害虫、杂草、病害）指标影响维度首次评估的各类数据输入、分析流程及衍生输出（含指标度量值）。若后续评估沿用本次首次评估的相同工作流与度量标准，即可实现五年时间尺度下的变化监测。

本次首次评估的指标设计、实施方法与研究结果详情，已收录于技术实施报告：Froese JG、Gooden B、Hulthen AD、Ponce-Reyes R、Burley AL、Cherry H、Hamilton M、Nipperess DA、Russell B、West P 与 Williams KJ（2021），《评估新南威尔士州外来入侵物种对生物多样性的威胁》，新南威尔士州规划、产业与环境部生物多样性指标计划实施报告，澳大利亚悉尼。

本次首次评估的核心结果与重点内容，已呈现于补充评估简报：DPIE（2021），《入侵物种：新南威尔士州生物多样性展望报告补充材料》，新南威尔士州规划、产业与环境部，澳大利亚悉尼。

指标说明：本指标围绕两个相互关联但独立测量的维度，量化新南威尔士州外来入侵物种（Invasive Alien Species, IAS）对本土生物多样性及生态系统质量造成的威胁：（i）暴露度，指外来入侵物种对本土生物多样性及生态系统质量的威胁存在范围、规模与程度；（ii）影响度，指外来入侵物种威胁对本土物种及生态群落造成的有害后果。在本次首次评估中，研究团队基于评估实施时易于获取的数据与知识来源，构建了多套度量标准以量化暴露度与影响度。

本数据集附带从技术实施报告中提取的外来入侵物种影响维度相关说明文档。该说明文档包含：（i）指标设计与实施方法的简要概述，（ii）涵盖数据输入、分析流程及衍生输出（含指标度量值）的技术工作流示意图与说明。
