Atlas of the vascular flora of the Iberian Peninsula biodiversity hotspot (AFLIBER)

Motivation: We accessed published and unpublished floristic sources to compile a comprehensive species list of the Iberian-Balearic terrestrial vascular flora and generate AFLIBER, an accurate floristic database of georeferenced plant occurrence records.

Main type of variable contained: Species distribution data totaling 1,824,549 plant occurrence records corresponding to 6,456 species and subspecies.

Spatial location and grain: The western Mediterranean, including inland territories of Spain, Portugal and Andorra and the adjacent archipelagos of Berlengas, Columbretes, and Balearic Islands, covered by 6,316 UTM quadrangular grid-cells of 10-km resolution.

Time period: All distributional trustable records were considered to create the AFLIBER database, most of them dating from the 1960s onwards.

Major taxa and level of measurement: Terrestrial vascular plant species and subspecies.

Software format: Data are supplied as comma‐separated text files (csv).

研究动机：本研究通过检索已发表及未公开的植物区系文献资料，整理得到伊比利亚-巴利阿里群岛陆生维管植物的全面物种名录，并构建AFLIBER数据库——一套包含精准地理参照的植物出现记录的高质量植物区系数据库。
数据集核心变量类型：共计1,824,549条植物出现记录，对应6,456个物种及亚种的分布数据。
空间范围与格网分辨率：研究区域覆盖西地中海区域，包含西班牙、葡萄牙、安道尔的内陆领土，以及周边的贝伦加斯群岛、科伦布雷特斯群岛与巴利阿里群岛；该区域被6,316个分辨率为10km的UTM四边形格网所覆盖。
时间跨度：为构建AFLIBER数据库，本研究纳入所有经过可信度验证的分布记录，其中绝大多数记录的采集时间可追溯至20世纪60年代并延续至今。
核心类群与分类层级：研究类群为陆生维管植物的物种及亚种。
数据格式：数据集以逗号分隔文本文件（CSV）格式提供。
