DEMNA-DNE : Exotic plant occurrences in Wallonia

Exotic plant occurrences in Wallonia is a merged occurrence-only dataset, compiling records of exotic taxa from various floristic data sources covering Wallonia (Southern Belgium). Data compilation, cleaning and validation were performed by the Département de l’Étude du Milieu Naturel et Agricole (SPW – DGARNE - DEMNA), in particular the 'GT-Flore', a working group bringing together plant experts from the department and external collaborators from regional naturalist networks. The types of primary sources compiled in this dataset are heterogeneous, including specific surveys, citizen observations, digitized collections, etc. Attention should therefore be paid to the "DC term: DataSetName" when figuring out record features. Also, Reference should be made to 'FootprintWKT' for spatial referencing, as the dataset includes both grid-derived and punctual data. "Flore OFFH and Co" (87 332 records) is the core of the DEMNA database. It covers monitoring carried out by the department officers or by partners under agreement, data from digitization calls, etc. "Encodage en ligne OFFH" (32 941 records) is the database associated to an online recording system for registered citizens (http://observatoire.biodiversite.wallonie.be/encodage/). The system includes georeferencing facilities and allows users to provide pictures. "BD Berce du Caucase", "Enquetes OFFH","Rinse", "Inv. Perm. des Res. For.","Natura 2000", "Contrats rivières" are topical surveys, limited in time and/or taxonomically oriented. All records have been subject to a validation procedure performed by the department experts. Validation rules were based on pictures, observer’s expertise, ecological relevance, or additional information provided by the observer. This dataset content is under a CC-BY license. Please make sure to quote the Département de l’Étude du Milieu Naturel et Agricole (SPW – DGARNE - DEMNA) if you make any use of the data, using preferably the form 'Origin of the Information: SPW-DGARNE – DEMNA – GT Flore & collaborators' whenever it is possible. Additional information is accessible upon specific and motivated request addressed to: http://observatoire.biodiversite.wallonie.be/cmdd/. Please contact the department for additional information about the dataset, about the Walloon 'GT-Flore', or about our biodiversity related activities.

Perm. des Res. For.”“Natura 2000”“Contrats rivières”均为专题调查数据集，具有时间限制或分类学针对性。 所有记录均经过该部门专家的验证流程，验证依据包括观测照片、观测者专业经验、生态相关性以及观测者提供的补充信息。 本数据集内容采用CC-BY授权协议发布。若您使用本数据集，请务必注明数据来源为自然与农业环境研究部（SPW – DGARNE - DEMNA），建议优先采用“信息来源：SPW-DGARNE – DEMNA – GT Flore 及合作者”的标注格式。 如需获取更多信息，请提交具体且有合理依据的申请至：http://observatoire.biodiversite.wallonie.be/cmdd/。您可联系该部门咨询本数据集、瓦隆地区“GT-Flore”工作组或我方生物多样性相关活动的更多信息。我们热忱欢迎您的反馈与意见。
