The distributional patterns of exotic plant species were measured in Wind Cave National Park, South Dakota. Seventeen exotic plant species were encountered within ninety 100 m by 1 m belt transects. The six most common species: Bromus japonicus Thunb. ex Murr., Bromus tectorum L, Melilotus alba Medic., Melilotus officinalis (L.) Pall., Poa compressa L., and Tragopogon dubius Scop. The distributions of these species were used to make a predictive statistical models based on logistical regression analysis with the following environmental variables: park roads, park trails, prairie dog towns, topography, fire history (for the past 59 years), game trails, stream beds, and proximity to road, trails, park boundary, and streams (all emphemeral).
