Data from: A comprehensive dataset on cultivated and spontaneously growing vascular plants in urban gardens

Rawdata of a survey of vascular plants in 85 urban gardens of the city of Zurich, Switzerland. Two sampling approaches were applied: (i) a floristic inventory of entire garden lots based on repeated garden visits, including all vegetation periods; and (ii) floristic sampling on two plots of standardized size (10 m2) per garden during the summer. We identified a total of 1081 taxa and report the origin status, i.e., whether a taxon is considered native or alien to Switzerland. Furthermore, the origin of a plant or garden population was estimated for each taxon and garden: each taxon in each garden was classified as being either cultivated or spontaneously growing. For each garden, the number of all native, cultivated, and spontaneously growing plant species is given, along with additional information, including garden area, garden type and the landscape-scale proportion of impermeable surface within a 500-m radius.

瑞士苏黎世市85个城市园林的维管植物（vascular plants）调查原始数据。本研究采用两种采样方案：其一为基于多次入园调查（覆盖所有植被季）的完整园林地块植物区系清查；其二为夏季于每个园林内设置2个标准面积（10 m²）样地开展的植物区系采样。本研究共鉴定出1081个植物分类群（taxa），并记录了各分类群的起源属性，即该分类群对于瑞士而言是本土物种还是外来物种。此外，针对每个分类群及其所在园林，研究还估算了其植物或园林种群的起源：每个园林内的各分类群被划分为栽培物种或自然逸生物种。本数据集同时提供了每个园林的本土、栽培及自然逸生植物物种数量，以及其他补充信息，包括园林面积、园林类型，以及该园林周边500米半径范围内的景观尺度不透水面（impermeable surface）占比。
