This dataset contains counts of pollinators visiting different varieties of oilseed rape (OSR). Data were collected from four trial sites in the UK in May 2012. The trial sites comprised of 20 varieties (plots) replicated in three blocks on each farm but only 2 of the blocks at each site were used for pollinator observations. Pollinator observations were also only made where there were greater than 30 percent of OSR plants in flower in the plot and only when weather conditions were within standardised limits. For each plot per site a six minute observation period was made during which the number of pollinators within the following taxon groups were counted: bumblebees to the species level, solitary bees identified to general body forms (Lasiglossum to genus level; Osmia separated to bicolour and rufa; Andrena separated to body forms typical of dorsata, carantonica, nigroaenea, haemorrhoa, fulva, flavipies, nitida, cineraria, bicolour and minuta), large hoverflies (> 12 mm), small hoverflies (< 11 mm), and Bibionidae. Each variety was observed for two separate six minute periods to reduce the impacts of minor fluctuations in weather that may reduce pollinator observations within single six minute periods. The dataset was collected as part of a project which aimed to identify key pollinators for OSR and identify if there are feeding preferences for individual varieties.

This dataset contains percentage cover of plants, mean numbers of aphids, mean counts of predators and mean counts of herbivores on three crops (field bean, wheat and oilseed rape) within different grassland types (improved, restored and species rich). Data were collected in 2013 on five farms in the Salisbury Plain area of the UK as part of the Wessex Biodiversity and Ecosystem Services Sustainability (BESS) project within the UK Natural Environment Research Council (NERC) BESS programme. This data set was used to provide an assessment of the potential for different grassland types to provide natural pest control ecosystem services. The study uses sentinel plants of the three crops established in the grasslands to monitor herbivorous pest insects, predatory insect occurrence and the population growth rates of artificially established aphids.

This dataset consists of farm management data which includes crop drilling dates and herbicide application dates. The data relate to arable fields in which a range of ecological measurements were collected, including species counts in the following areas: weed seedbank, vegetation in the crop, field edge vegetation, invertebrates. Each field was sown with a combination of genetically modified and conventional crops, either Beet, Maize, Spring-sown Oilseed Rape or Winter-sown oilseed Rape. The data were collected as part of the Farm Scale Evaluations (FSEs), a four-year programme of research by independent researchers aimed at studying the effect that the management practices associated with Genetically Modified Herbicide Tolerant (GMHT) crops might have on farmland wildlife, when compared with weed control used with non-GM crops. Data were collected by a consortium of: the Institute of Terrestrial Ecology, ITE (now the Centre for Ecology & Hydrology, CEH), the Institute of Arable Crop Research (now Rothamstead Research, IACR) and the Scottish Crop Research Institute, SCRI (now the James Hutton Institute, JHI). Data were collected for four crops overall (Beet, Maize, Spring-sown Oilseed Rape and Winter-sown oilseed Rape).

This dataset contains data on insects observed visiting flowers of three crops (apples, field beans and oilseed rape) and responses by recorders to a questionnaire asking about their experience carrying out pollinator surveys. Data from thirteen flowering crop fields was collected by teams based at the University of Reading and the James Hutton Institute in Scotland. Data was collected by different recorders, some of whom were novice data collectors, experienced researchers or farmers and agronomists. Recorders were asked to implement three methods: pan trapping, transect walking and/or hand pollination and plant bagging. Transects involved walking a 50m transect recording floral visitors to crop flowers within a 1m squared moving observation widow next to the recorder. Pan trapping involved placing out three coloured water trap arrays along a 50m transect and then recording what flying insects were caught in the water traps at the end of the survey. Hand pollination and plant bagging involved putting mesh bags over flowers to exclude visitation by insects, hand pollinating crop flowers and counting and marking flowers with cable ties. Data were collected between April and July 2015 from sites across the UK. Full details about this dataset can be found at https://doi.org/10.5285/5822900b-3af4-4bb9-a2d6-0b5d384e2a3c

This dataset consists of a range of ecological measurements collected from a set of arable fields, each sown with a combination of genetically modified and conventional maize crops. Measurements include species counts in the following areas: weed seedbank, vegetation in the crop, field edge vegetation, invertebrates. The data were collected as part of the Farm Scale Evaluations (FSEs), a four-year programme of research by independent researchers aimed at studying the effect that the management practices associated with Genetically Modified Herbicide Tolerant (GMHT) crops might have on farmland wildlife, when compared with weed control used with non-GM crops. Data were collected by a consortium of: the Institute of Terrestrial Ecology (now the Centre for Ecology &Hydrology), the Institute of Arable Crops Research (now Rothamsted Research) and the Scottish Crop Research Institute (now the James Hutton Institute).

The number and type of pollinators in winter-sown oilseed rape fields (Brassica napus L.) in relation to local plant diversity (in crop and field margin) and landscape characteristics. Pollinators were collected using two methods (pan traps and transects). Local plant diversity was assessed using quadrats in field margins and in cropped area. The presence of hedges was also recorded. Landscape characteristics included the presence of patches of grassland of different biodiversity levels and the amount of grasslands and other semi natural habitat within a 0.5 - 3km radius circular buffer of the collection points. Data were collected over two years (2014-2015). 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 https://doi.org/10.5285/6128a4f7-d2ac-43c5-b492-af4c654e89b8
