Map of Critically Endangered Ecological Communities NSW Version 6.0

As of __05 May 2021__ this map data has been superseded for operational use by [Threatened Ecological Communities Greater Sydney](https://datasets.seed.nsw.gov.au/dataset/threatened-ecological-communities-greater-sydney). The CEEC product is no longer being maintained.\r\n\r\nThese map data contain a subset of NSW and Commonwealth listed Critically Endangered Ecological Communities (CEEC) within NSW. Version 6.0 (February 2020) contains minor adjustments to reflect change in NSW listing status of Sydney Turpentine-Ironbark Forest in the Sydney Basin Bioregion from EEC to CEEC. Version 1 only contained NSW CEECs. Further details regarding the updating of previous versions are provided under Lineage.\r\n\r\nThis composite map was derived from the extraction of relevant vegetation map units contained in a variety of existing vegetation maps held in the Office of Environment and Heritage (OEH) VIS (Vegetation Information System) Map Catalogue. Please note that not all Listed CEECs are currently represented in this dataset. Reasons include: \r\n\r\n1. the CEEC has not yet been mapped; \r\n2. the CEEC has been mapped but the source data are not yet openly available (see Supplemental Information for details). \r\n\r\nFurther CEECs may be added in future versions of this dataset.\r\n\r\nNote, there is no formal process in place to guarantee correction in the source maps that are transferred to this composite map product.\r\n\r\nEcological communities are included in the critically endangered category of the Threatened Species Conservation Act, 1995, if they are facing an extremely high risk of extinction in NSW in the immediate future. Critically Endangered is also a category under the Environment Protection and Biodiversity Conservation Act, 1999.

截至2021年5月5日，本地图数据的业务使用已被[大悉尼受威胁生态群落](https://datasets.seed.nsw.gov.au/dataset/threatened-ecological-communities-greater-sydney)替代，本极危生态群落（Critically Endangered Ecological Communities，CEEC）产品已停止维护。

本套地图数据收录了新南威尔士州（New South Wales，NSW）及澳大利亚联邦名录中收录的部分新南威尔士州境内极危生态群落（CEEC）。6.0版本（2020年2月）针对悉尼盆地生物区内的悉尼番樱桃-铁桉林的新南威尔士州名录等级调整作出小幅修正，将其从濒危生态群落（Endangered Ecological Communities，EEC）升级为极危生态群落（CEEC）。首个版本仅收录新南威尔士州境内的CEEC。各旧版本的更新详情详见「谱系（Lineage）」章节。

本合成地图的制作源自环境与遗产局（Office of Environment and Heritage，OEH）植被信息系统（Vegetation Information System，VIS）地图馆藏中各类现有植被地图的相关植被制图单元提取。请注意，本数据集并未收录全部名录收录的CEEC，具体原因包括：
1. 该CEEC尚未完成制图；
2. 该CEEC已完成制图，但源数据尚未公开（详细信息见补充材料）。

本数据集的后续版本或将新增更多CEEC。

请注意，本合成地图所依托的源地图未设置正式校正流程，无法确保其修正的准确性。

依据1995年《濒危物种保护法》，若某生态群落在新南威尔士州境内面临极高的近期灭绝风险，则将其归入极危等级。「极危」同时也是1999年《环境保护与生物多样性保护法》中的分类等级。
