Summary Data: Introduced Species Occurrences by Terrestrial Ecoregion

Summary of species occurrence data from 1900 to 2020 for Australian terrestrial species organised by IBRA region and status as an introduced or invasive species using the Global Register of Introduced and Invasive Species (GRIIS) list for Australia. Counts are provided by species and IBRA region for:\r\n\r\n1.\tThe total number of occurrence records within the region, for a given GRIIS status and time period\r\n2.\tThe number of distinct species recorded within the region, for a given GRIIS status and time period\r\nThe GRIIS list identifies species that are known or believed to have been introduced to Australia. Species that are not included in the GRIIS Australia list are treated here as native species. The GRIIS list also identifies a subset of introduced species as invasive species based on knowledge that these species have had a harmful impact. This dataset organises species occurrences using these GRIIS data to assign species to one of three categories:\r\n\r\n1.\tNative – not an introduced species\r\n2.\tIntroduced – an introduced species that is not considered invasive\r\n3.\tInvasive – an introduced species that is considered invasive \r\n\r\nThe GRIIS lists have been compiled by experts with knowledge of introduced and invasive species in each country and are still being improved. It should particularly be noted that version 1.6 of the GRIIS Australia list includes a number of species which are native to Australia but which have been translocated to new parts of the country for conservation purposes. In future versions of the GRIIS Australia list, these species will be appropriately identified and can be excluded as required. This is important since the list does not indicate the areas in which the species is considered to have been introduced (including translocated). These species were manually excluded before the dataset was generated, but this version should be treated with caution. Future versions of this dataset will benefit from improvements to the GRIIS Australia list. \r\n\r\nOccurrence records were aggregated and organised by the Atlas of Living Australia (ALA, https://ala.org.au/) and include survey and monitoring data collected and managed by the Integrated Marine Observing System (IMOS, https://imos.org.au/) and the Terrestrial Ecosystem Research Network (TERN, https://tern.org.au/). \r\n\r\nTo find out more about this dataset, visit: https://ecoassets.org.au/data/summary-data-introduced-species-occurrences-by-terrestrial-ecoregion/\r\n\r\n__DOI: https://doi.org/10.26197/ala.206e6580-ac7c-42c3-aaca-79256897bd57__本数据集为1900年至2020年澳大利亚陆生物种的出现记录汇总，依托澳大利亚《全球外来入侵物种名录（Global Register of Introduced and Invasive Species, GRIIS）》，按IBRA区域（Interim Biogeographic Regionalisation for Australia）划分，并按外来/入侵物种状态进行分类。统计维度按物种及IBRA区域划分，涵盖以下两类指标： 1. 给定GRIIS物种状态与时间周期下，对应区域内的出现记录总数量 2. 给定GRIIS物种状态与时间周期下，对应区域内记录的不同物种总数 GRIIS名录用于识别已知或疑似已传入澳大利亚的物种。未纳入澳大利亚GRIIS名录的物种，本数据集将其视为本土物种。此外，GRIIS名录还基于物种已造成有害影响的判定依据，将部分外来物种归类为入侵物种。本数据集依托上述GRIIS数据对物种出现记录进行归类，将物种划分为以下三类： 1. 本土物种（Native）——非外来物种 2. 外来非入侵物种（Introduced）——已传入澳大利亚但未被认定为入侵的物种 3. 入侵物种（Invasive）——已传入澳大利亚且被认定为造成有害影响的物种 GRIIS名录由各国外来及入侵物种领域专家编制，目前仍在持续完善中。需特别说明的是，澳大利亚GRIIS名录1.6版包含部分本土物种——这些物种因保护目的被迁移至澳大利亚境内的新分布区域。在未来版本的澳大利亚GRIIS名录中，这类物种将被明确标识，并可根据需求剔除。由于该名录未标注物种被传入（包括人为迁移）的具体区域，因此这一点尤为关键。本数据集生成前已手动剔除了这类物种，但使用当前版本时仍需谨慎。后续版本的本数据集将随着澳大利亚GRIIS名录的完善得到优化。 本数据集的物种出现记录由澳大利亚生命图谱（Atlas of Living Australia, ALA）汇总整理，涵盖了综合海洋观测系统（Integrated Marine Observing System, IMOS）及陆地生态系统研究网络（Terrestrial Ecosystem Research Network, TERN）收集并管理的调查与监测数据。 如需了解本数据集的更多信息，请访问：https://ecoassets.org.au/data/summary-data-introduced-species-occurrences-by-terrestrial-ecoregion/ __DOI: https://doi.org/10.26197/ala.206e6580-ac7c-42c3-aaca-79256897bd57__
