Low-tech tracer beads reveal that moss turf traps wind-borne seeds that bare ground loses

Evidence

Aimee went to the bead store and bought vials of plastic beads in the brightest possible colors. Sometimes our kind of science needs more creativity than high-tech equipment. She carefully placed the beads in a grid pattern on different kinds of surfaces at the mine—the bare tailings, under shading vegetation, and on the moss carpet. Every day she would come back and count them. Within two days, every bead on the bare tailings was gone, blown away and buried in the shifting sand. A few more persisted under the wildflowers, but the record setter was Polytrichum. The beads became lodged between the shoots, safe from the wind. — Robin Wall Kimmerer, Gathering Moss, 231
