Japanese Stiltgrass (Microstegium vimineum)

“Microstegium vimineum is listed by the US Forest Service as one of only 26 Category 1 invasive plants in the Eastern Region of the USA; these are described as highly invasive plants which invade natural habitats and replace native species ( Furthermore, M. vimineum was recently ranked as the number one invasive plant of concern by researchers and land managers in the Eastern USA.”

-Microstegium vimineum (Trin.) A. Camus

August 2010 Video: 2010 Stiltgrass Summit
The River to River Cooperative Weed Management Area hosted a research and management summit on the invasive Japanese stiltgrass (Microstegium vimineum) at Southern Illinois University in Carbondale, Illinois. August 11-12, 2010.


The Stewardship Network has promoted stiltgrass education in two webcasts.

Causes and Consequences of Microstegium Vimineum (Japanese Stiltgrass) Invasion
Luke Flory actually did his dissertation on stiltgrass in Indiana. This 2010 webcast highlights his early research.

A Conversation on Japanese Stiltgrass
By 2017 Luke Flory had become an international figure in stiltgrass management. He joined the MIVI in Scio team of Jim Odell and Andrea
Matthies for this update on his research and the documentation of stiltgrass in Scio Township in August 2017.


Comparisons between stiltgrass and other grasses

Field Guide that contains a good caparison
– The last four pages of the Field Guide to the identification of Japanese Stiltgrass contains very useful comparisons between stiltgrass and other grasses ‹both native and non-native ‹grasses with some similarities.

What George Ainslie’s discovery means to us
– Our native Leersia v. (cutgrass) is perhaps the most similar to Microstegium v.  The best comparison of the two was done by Les Mehrhoff in his keynote speech for the 2010 Stiltgrass Summit (somewhat after the 20 minute mark).

The Flory Lab
Luke Flory oversees Research in the Flory Lab at the University of Florida covers a wide variety of topics in plant and ecosystem ecology with a focus on non-native plant invasions and agroecology–particularly stiltgrass.
