Description

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.
