karsob@man.poznan.pl https://orcid.org/0000-0001-7012-9756 Data were compiled from field records and laboratory documentation. Geographic coordinates were standardized to the WGS84 system. Taxonomic names were harmonized, and authorship information was separated from scientific names. The dataset was structured according to Darwin Core standards and prepared for publication in GBIF. The study covers populations of Juniperus species distributed across Europe, Western Asia, and the Mediterranean region. Sampling was conducted between 2001 and 2015 in natural habitats representing the geographical range of the studied taxa. Samples of cones and short segments of shoots from the most recent growth were collected separately from the southern side of individual trees, at a height of approximately 1.0–2.5 m above ground level. Plant material was collected from natural populations, with samples taken from different parts of the canopy to ensure representativeness. Each sampled individual was georeferenced using GPS or, when necessary, later georeferenced based on locality descriptions. Species identification was verified by taxonomic experts. Geographic coordinates were checked for consistency and converted to decimal degrees when necessary. Data were standardized according to Darwin Core standards and validated prior to publication.
