Data from flower margins support natural enemies adjacent to apple orchards but evidence of spill-over is mixed

Data were collected from ten conventional commercial apple orchards in Kent, UK. They include; 1) abundance and identification of arthropods collected via transect sweep sampling from four orchard habitats (flower margins and the tree alleyway 50 m from the orchard edge in flower margin orchards, and grass headland and tree alleyway 50 m from the orchard edge in control orchards) along with sward height which was recorded from the corner of each quadrat during vegetation assessments using a measuring tape, 2) abundance and identification of arthropods collected via transect tap/beat sampling from apple trees in flower margin orchards and control orchards up to 50 m from the orchard edge (separate documents were used to record 2021 and 2022 data), 3) percentage cover of plant species recorded from six orchard habitats (flower margins and both the tree alleyway and understory 50 m from the orchard edge in flower margin orchards, and grass headland and both the tree alleyway and understory 50 m from the orchard edge in control orchards).
