Wavyleaf basketgrass


I was recently asked to begin investigating a new forest invasive in from Maryland: wavyleaf basketgrass  (Oplismenus hirtellus ssp. undulatifolius), which Pennsylvania foresters were also recently alerted about. In the image, the green understory is completely covered by wavyleaf basketgrass, which is typical of the sites that it invades in Maryland. Similarly to Japanese stiltgrass, wavyleaf basketgrass grows in high density stands in forest understories and is thought to threaten native plant diversity.  My collaborator Vanessa Beauchamp is conducting field experiments on wavyleaf basketgrass invasions, and we will synthesis this information in simulation models, to understand the implications of these results for larger-scale spread. Catching an invasion this early in the process gives us the best chance to potentially eradicate this species, which is the most cost-effective way to deal with an invasion.
