Economic Botany Section Castle, Lisa [1]. Prairie Turnips Ten Years Later. Prairie turnips (Pediomelum esculentum Fabaceae) have a long history of harvest for their edible roots by peoples across the species’ native range on the North American Great Plaints. Fates of individuals in three non-harvested populations, one in Kansas, one in Nebraska, and one in Montana, were tracked from 2001 to 2004, while different levels of harvest were experimentally mimicked to determine effect of harvest-like disturbance on seedling recruitment. This information was used in 2006 to project population size and model level of sustainable harvest under many different harvest regimes. Plots in Kansas were re-visited in 2013 and 2014 and the resulting information used to compare projected changes to that of the observed population size and structure at the end of the ten year period and to re-evaluate sustainability of harvest.
