Harvested Sweetgrass Outgrew the Untouched Plots
Kimmerer's graduate student Laurie tested basket makers' claim that sweetgrass flourishes when people harvest it. She set up plots harvested by pulling individual stems or taking handfuls, alongside unharvested controls. The harvested plots grew back denser, while the untouched plots declined and became choked with old growth, which suggests that careful human taking can be a service the plant depends on.
