Data underlying the paper: Multi-species productive grasslands offer advantages over permanent grasslands for arthropod conservation, but preserving semi-natural grasslands remains essential

This datasets contains the results of both pollinator counts and pyramid catches. Data was collected in the East of the Netherlands in the region 'achterhoek'. All locations had sandy soils. Treatment types were semi-natural grasslands (SNG), multi-species grasslands (MSG), and permanent, conventional grasslands (PG).
