  1. Create patches of bare ground for ground-nesting bees

    Nest density of ground-nesting bees and wasps was increased by removing plant cover, or digging and raising soil, in trial plots at five sandy grassland sites in Baden-Württemberg, southwest Germany in 1992, relative to five control sites (Wesserling & Tscharntke 1995). Digging and raising soil was more effective at increasing nest density. Raking was not very effective, because it generated a dense plant cover.
