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

Japanese stiltgrass, also called Nepalese browntop or eulalia, is an aggressive invader of forested habitats in the eastern United States. The Stiltgrass Summit featured presentations, panel discussions, field trips, and poster sessions. Nearly 100 people attended from 12 different states. Keynote speakers for the summit were Dr. Les Mehrhoff, University of Connecticut/Invasive Plant Atlas of New England and Mike Ielmini, National Invasive Species Program Coordinator, USDA Forest Service.

All oral presentations and panel discussions at the Stiltgrass Summit were recorded and are now available to view, for free, at this website. It is our hope that the materials presented at the summit remain a useful resource for anyone seeking information on the ecology, impacts or management of Japanese stiltgrass.

As a response to the 2010 Stitlgrass Summit, a synopsis of the presentations and discussions was written by Gage et al. (2011) as a white paper. This document summarizes the history, biology, impacts, and management of Japanese stiltgrass and incorporates recent research not discussed at the Summit. That white paper is available as a free download from the River to River CWMA.

Additional Information on Japanese Stiltgrass

A literature review and summary of Japanese stiltgrass was recently published on the USDA – Forest Service’s Fire Effects Information System website (see Fryer 2011).

Angie Shelton, University of Indiana, has a website that expands upon her research presented at the Stiltgrass Summit.

Luke Flory, University of Indiana, has researched ecology and management of Japanese stiltgrass. His website is a good resource.

The University of Georgia Center for Invasive Species and Ecosystem Health has compiled lots of images and links to information for Japanese Stiltgrass.

The University of Georgia also runs the Early Detection and Distribution Mapping System (EDDMapS) program. Go to that website to view distribution maps of Japanese stiltgrass and to submit new records
