Interpretive Summary:

Technical Abstract: Background/Question/Methods: Perennial invasive plants have the potential to alter all aspects of their new environments. In the northeastern United States, pale swallowwort (Vincetoxicum rossicum (Kleopow) Barbar.) , a member of the milkweed family that is native to southern Europe, forms dense monocultures during the growing season that are thought to alter native plant populations. However, it is unknown if these summer growing species impact other native plants, such as spring ephemerals, which complete their growing seasons prior to the emergence of pale swallow wort. We conducted our study at two locations in central New York: the Musgrave Research Farm at the Cornell University Agricultural Experimental Station in Aurora, NY and at Robert G. Wehle State Park, located on the shore of Lake Ontario in Henderson, NY. We established 8 paired plots, 8 with no pale swallowwort and 8 with pale swallowwort at Musgrave Farm, but only 8 plots at Wehle since pale swallowwort populations were continuous with no control areas. Plots were sampled in 2011, 2015 and 2017 by counting individual plants of each species within 0.5 x 1-m subplots during late April/early May. Data were analyzed using Analysis of Variance to investigate differences between years and treatments.
