Luxembourg National Tree Registry

An integrated open dataset fusing Luxembourg's openly available individual-tree sources into one harmonized schema, with per-tree provenance, commune assignment, and cross-source de-duplication flags. Version 1.0 comprises 148,974 located tree records across all 100 Luxembourgish communes, from the ANF remarkable-tree (238) and Cormier (964) registers, the ACT national isolated-tree (43,900) and tree-row (16,738) layers, OpenStreetMap (87,131), and a small Wikidata heritage set (3). It is published as a Collective Database in separate files by licence: a CC0 core (the non-OSM sources, 61,843 records) and an OpenStreetMap layer under ODbL (87,131 records). Photographs are referenced (URL + attribution), not redistributed. See LICENSE.md and PROVENANCE.md. To our knowledge, this is the first fusion of these sources into one national tree registry. Further description is provided within the included markdown files.
