Abstract

In the last two decades the exotic plant sickleweed (Falcaria vulgaris Bernh., Apiaceae) has invaded, and come to dominate, large areas of the Fort Pierre National Grassland (FPNG) in central South Dakota, USA. Currently sickleweed is estimated to infest over 3200 ha of FPNG. The purpose of this study was to examine several of the biological and ecological traits that may contribute to the invasiveness of sickleweed in FPNG. Specifically, I researched germination characteristics of sickleweed seed collected from FPNG, the effect of sickleweed on other grassland vegetation in FPNG, and vegetative reproduction and regeneration of sickleweed from roots.
