  • Plant-pollinator interactions database derived from biological recording data, unpublished experimental data and published interactions in books and papers.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 list of pollinator species caught within pan traps from habitats comprising different floral cover. Data were collected from the Hillesden estate, Buckinghamshire in June 2015. Surveys were conducted alongside four experimental arrays of the Californian poppy, Eschscholzia californica, located with two habitats; a sown wildflower mix and bare, fallow ground. This set-up was repeated over four 100ha blocks separated at a distance greater than 500m. Pan traps comprised three water-filled circular plastic bowls (80 x 200 mm) painted with non-toxic fluorescent paint (1 yellow, 1 blue and 1 white; UV Gear, UK) placed in the centre of each array. Traps were deployed for 24 hours at each of the 16 arrays on the same day, twice weekly over the 16 day study period (totalling four surveys). Each survey was done in randomised order, between 0930 and 1700. All insects from the main pollinator groups (Hymenoptera: Apoidea, Diptera: Syrphidae and Lepidoptera) were counted and identified to species level. The intertegular span (the distance between the wing bases) of each insect from the main pollinator groups was then measured using digital callipers. The dataset was part of a larger experiment looking at the effect of floral resources on the pollination services to isolated plants. Full details about this dataset can be found at

  • The number and type of natural enemies of crop pests found in winter-sown oilseed rape fields (Brassica napus L.) in relation to local plant diversity (in crop and field margin) and landscape characteristics. Natural enemies and pests were collected using two methods (suction sampling and pitfall traps). Local plant diversity was assessed using quadrats in field margins and in cropped area. The presence of hedges was also recorded. Landscape characteristics include the amount of mass flowering crops, arable land, presence of patches of different grassland types (intensive, restored and species rich) and the amount of grasslands and other semi natural habitat with up to a 3km radius of the collection points. These data were collected as part of Wessex BESS project, funded by the NERC Biodiversity and Ecosystem Service Sustainability research program. This dataset can be used in conjunction with other Wessex BESS WP4 datasets. Full details about this dataset can be found at
