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).
