Database

The EuPPollNet (European Plant-Pollinator Networks) database is a fully open European-level database containing harmonised taxonomic data on plant-pollinator interactions referenced in both space and time, along with other ecological variables of interest.

This dataset was produced in the framework of the work package 1 (task 1) of the Horizon EU project Safeguard. We aimed to mobilise EU experts and data to compile and make available distributional data for bees, butterflies, moths and hoverflies. This will allow us to assess the magnitude, scale and extent of status and trends in pollinator distributions, diversity, abundance, communities and plant-pollinator networks.

This dataset was produced in the framework of the work package 1 (task 2) of the Horizon EU project Safeguard. The dataset encompasses trait data for three groups of pollinators: wild bees, hoverflies and butterflies, as well as phylogenetic data extracted from the GenBank. Information on traits comes from different literature sources, as well as direct measurements in collections and published databases.

This dataset includes data files and R scripts supporting our European level, re-analytical, data-synthesis on impacts of pollinator-friendly management in urban habitats. These files include vegetation, floral and pollinator datasets from European case studies.

This dataset supports the study "Using total abundance as a proxy for wild bee species richness: A practical tool for non-experts". We collated a large dataset of published and unpublished primary data from 63 independent regional studies on wild bee communities sampled in different habitats and climates across Europe using both pan-traps and transect walks.

This study compared semi-natural grassland offsets and paired reference grasslands located across the Netherlands using transect walks, flower counts, and vegetation surveys. We assessed wild bee and hoverfly abundances, species richness, and community composition, and flower and vegetation diversity.

This study explores the potential of biodiversity offsetting through restoration of forests in supporting pollinators in temperate agricultural landscapes. We compared understory pollinator communities between 17 lowland oak-hornbeam restored forest patches older than 20 years with those observed in 17 natural forest remnants, referenced here as the target habitat of ecological restoration.

These files contain the data and code used in analysing the effect of road verge management and adjacent traffic impacts on abundance and diversity of pollinators within road verges.

The datasets for the manuscript “Landscape-level oilseed rape cover shapes seasonal patterns of wild bee abundance in conservation areas” include the name and coordinates of the sampling sites, the response variable bee abundance (distinguishing between the timing of OSR flowering and bee traits) and the predictor variables OSR cover (2022/2021), habitat area, mean field size, nesting sites, flower cover, flower richness and annual mean temperature.

In this study, we established diverse native wildflower plantings within heterogeneous and homogeneous agricultural landscapes, by two spatial configurations: one large field or three smaller strips, in Hungary. We sampled floral resources and wild pollinator insects (wild bees, hoverflies, butterflies), in early and mid-summer, for two years after establishment.
