The DUCP collection contains arthropods caught in pitfall traps from the summers of 2018, 2019, and 2021.Traps were placed along a 150m transect with traps located at 0m, 75m, and 150m. There were two transects per site: one starting from the field margin and one begining at a praire pothole edge.   Sites sampled include five seeded grasslands, four native prairies, five canola fields, three barley fields, and two wheat fields located within 100km of Saskatoon, SK, Canada.
