Data comprise flower abundance and diversity data and bee abundance, diversity and activity data collected during extensive surveys carried out on farms in Hampshire and West Sussex, southern England between 2013 and 2015. The pollen diets of wild solitary bees were quantified using direct observations and pollen load analysis. The purpose of the study was to provide valuable information to scientists, governments and land managers in designing more effective measures to conserve the broader wild bee community on agricultural land. The work was funded by the Natural Environment Research Council grant NE/J016802/1 and the Game and Wildlife Conservation Trust.
