  • 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

  • This dataset contains arthropod species presence and abundance data, species trait data and environmental data for arable reversion sites in southern England. A chronosequence of 52 arable grassland restoration sites and five target National Nature Reserve grassland communities were sampled for arthropods in 2014. These sites were located on calcareous soils. The majority of these sites were established as part of the South Downs Environmentally Sensitive Area (ESA), South Wessex Downs ESA, as well as through subsequent agri-environmental schemes including Countryside Stewardship or Higher Level agri-environment. Restoration sites ranged in age (1 to 30 years), habitat quality (e.g. sward structure and floral similarity to target grasslands), management (cutting and grazing) and surrounding landscape (isolation and cover of grassland). This environmental variation was captured and is included in the data set. Arthropods were identified across a wide range of trophic groups (detrititvores, herbivores, predators and pollinators). For arthropod species identified to species, information on functional traits is derived, including body mass, dispersal ability and trophic group. Full details about this dataset can be found at
