  • This web map service shows bee nectar plant richness across Great Britain . The source data uses counts of bee nectar plants in Countryside Survey area vegetation plots in 2007 and extrapolates to 1km squares across GB using a generalised additive mixed model. Co-variables used in the model are Broad Habitat (the dominant broad habitat of the 1km square), air temperature, nitrogen deposition, precipitation and altitude. The map has the following layers: plantCount = a modelled estimate of the count of all bee nectar plants within a 1km by 1km square, SEM = a measure of the variance of the plantCount attribute Understanding the distribution of bee nectar plants does provide valuable information on the potential distribution of pollinators and hence pollination.

  • The dataset contains information on the species identity and frequency of all insect-flower interactions recorded in 10 birch (Betula spp.) woodland fragments surveyed in 2009 (May-August). The data were collected in two transects (50 x 2m; 15m apart and at least 50m from the woodland edge) randomly situated prior to the onset of flowering in the centre of each wood. Five of the woodland sites were disturbed by cattle grazing, while five were undisturbed. Landowners confirmed that livestock had been absent for at least 70-100 years in undisturbed sites. Where livestock were present, cattle grazing was light to moderate (e.g. 2007: mean = 8.4 cattle ha-1) and long term (mean = 33 years). The dataset comprises 13 columns, 2002 rows and is 218 KB. It gives the site name, geographic coordinates, whether it was disturbed by cattle grazing or not, the wind speed and temperature at time of sampling, the date of sampling, and the identity of the insect and plants interacting (binomial name or recognisable taxonomic unit).

  • This dataset consists of nectar sugar values of common British plant species. The data were collected during field surveys taking place from February to October in 2011 and 2012. The majority of field sites were located in the south of England. The data were collected under a project named 'Agriland' ( Linking agriculture and land use change to pollinator populations) based at the University of Bristol, as part of the UK Insect Pollinators Initiative. The Insect Pollinators Initiative (IPI) was funded by Biotechnology and Biological Sciences Research Council (BBSRC), Natural Environment Research Council (NERC), Department for Environment, Food and Rural Affairs (Defra), the Scottish Government and the Wellcome Trust, under the auspices of the Living With Environmental Change (LWEC) partnership.

  • This dataset contains data on pollinating insects, floral resources, and environmental conditions from a pollinator monitoring pilot conducted from 2015. Data were collected from a total of 14 sites across the UK, over four sampling rounds from April to August 2015. Half of the sites visited were dominated by agricultural habitats (e.g. crop fields and pasture) and half were dominated by semi-natural habitats. These data were collected to compare methods for sampling pollinators; compare the capacity of different recorder groups to implement different survey methods; gather feedback from recorders on the survey methods; and generate detailed information on implementation costs and support requirements for each method. Three different types of recorder groups were trialled (researcher, consultant, volunteer) using different combinations of sampling methods (pan trapping, fixed transects pollinator survey, fixed transects flower survey, timed focal flower observations, standardised "free search" pollinator survey).

  • [This dataset is embargoed until August 6, 2022]. This dataset contains records on the abundance and species richness of wild bees along transects in ten 1x1 km survey squares of the Leighfield forest region of Leicestershire and Rutland, UK collected in the Spring and Summer of 2020. The dataset also contains a 10 m resolution raster land cover map of the survey sites and spatially referenced GIS files of the survey transect paths. The work was carried out by the data authors to assess pollinator abundance and species richness within the rural landscape of Leighfield Forest. The research was funded through NERC Grant Reference : NE/L002493/1Central England NERC Training Alliance (CENTA) Full details about this dataset can be found at https://doi.org/10.5285/4f4d2ef6-2f31-4aa6-aa1a-fe79cc6d6b04

  • Plant-pollinator interactions database derived from biological recording data, unpublished experimental data and published interactions in books and papers. The database covers all recorded interactions for bees, hoverflies and butterflies in mainland GB. Interactions were inferred from biological recording metadata by algorithmically screening for text matching a valid scientific or vernacular plant name (or a widely used synonym or abbreviation of either), followed by manual data cleaning. These data were compiled for the construction of multiple potential plant-pollinator networks in combination with plant and pollinator occurrence data.

  • This dataset contains a colony performance indicator monitored from Bumblebee colonies of similar mass after 43-48 days in the field. The weight in milligrams (mg) is given of each surviving bee recorded as it was removed from the outside of the nest as we progressed towards the nest core. Bumblebee colonies of similar mass were provided with sugar syrup (UT, n=12), containing chlorpyrifos (CP, 150 nanomolar nM, n=6) imidacloprid (IMD, 10 nM, n= 6) or both (IMD + CP, n=12). No pollen was provided and bees were free to forage in a wilderness/grassland area in the west of Scotland. The data were collected as part of a project within the UK Insect Pollinators Initiative (2010-2015).

  • This dataset contains pollinator abundance data from 13 calcareous grassland, 13 heathland and 12 woodland sites within Dorset, UK. The sites were selected to represent a range of habitat types across a condition gradient as measured by levels of degradation from the original habitat. The original habitats were identified as being calcareous grassland, heathland or woodland from a survey conducted in the 1930s. Butterflies, bees, hoverflies, flies and beetles were recorded to species level and the plant species insects were foraging on was also recorded. Data were collected on three different dates in 2017 and 2018: calcareous grassland in June, July and August; heathland transects in May, August and September; and woodland transects in May, June and July.

  • Land use/land cover (LULC) map of a 20km2 agricultural landscape centred on the Hillesden Estate, Buckinghamshire, UK. The map is based on remote sensed data (LiDAR and hyperspectral sensors) with manual updates and the addition of spring and summer floral cover data from comprehensive field surveys. The remote sensed data was generated in August 2007. The manual updates and summer floral data were from field visits in July and August 2011, and the spring floral data were from field visits in April 2011 and 2012. The map was created as part of a project led by the Centre for Ecology & Hydrology, funded under the Insect Pollinators Initiative.
