Data from: neglected puzzle pieces of urban green infrastructure: richness, cover, and composition of insect-pollinated plants in traffic-related green spaces

Insect-pollinated vascular plants in spontaneous vegetation provide
essential ecosystem services and benefit wildlife. However, floral
communities associated with traffic-related green spaces are rarely
considered valuable elements of urban green infrastructure (UGI). The
dataset contains information on species-based floral communities of
vascular insect-pollinated plants in traffic-related green spaces in three
highly populated Finnish cities. Those are Helsinki (665 558 inhabitants),
Tampere (244 029 inhabitants), and Turku (175 645 inhabitants). Data were
collected during the mean flowering phenophase of vascular plants in
July-August 2022 from two types of locations: (i) urban (city centers) and
(ii) suburban (city outskirts), and from three types of traffic-related
green spaces: (i) traffic islands, (ii) parking lots, (iii) road verges.
The dataset contains information for the 93 vascular insect-pollinated
plant species flowering during the survey. Sampling campaign was conducted
in 90 sampling sites, and the dataset contains information on the location
coordinates. In addition, the dataset possesses information on the amount
of garbage pieces (cigarette filters, plastic boxes, or scraps) revealed
for each sampling point in traffic-related green spaces.
