DEMNA-DNE : Early warning system on Introduced Species in Wallonia

Early warning system on Introduced Species in Wallonia is a presence-only dataset aimed to deliver in real time the occurrence records of introduced species within Wallonia. Data are aggregated from various online recording systems that are maintenaid by the Département d'Étude du Milieu Naturel et Agricole (SPW-DEMNA). Among these encoding systems, we find OFFH (Observations Faune Flore Habitats), the main occurrence encoding platform for the department experts and partners. But also specific surveys on exotic species (e.g. on the Giant Hogweed) open to the general public and thus based on citizen participation. As this dataset aims to feed an alert system on exotic species, it also include non-validated data and attention should be paid to the validation status of the records! If you have any return or remark, please do not hesitate to contact the Department for further details.瓦隆大区外来引入物种预警系统数据集是一份仅存在记录数据集（presence-only dataset），旨在实时提供瓦隆大区境内外来引入物种的出现记录。本数据集的数据由比利时瓦隆大区自然与农业环境研究部（SPW-DEMNA）维护的各类在线记录系统汇总整合而来。 在这些记录系统中，既有OFFH（动植物与栖息地观测系统，Observations Faune Flore Habitats）——该部门专家与合作方主要的物种出现记录编码平台，也包含面向公众、依托公民科学参与的外来物种专项调查数据（例如针对大猪草的调查）。 由于本数据集旨在为外来物种预警系统提供数据支撑，其中包含未经审核验证的记录，因此请务必关注各条记录的审核状态！ 若您有任何反馈或意见，敬请联系该部门以获取详细信息。
