Japanese stiltgrass update: “degree of alarm”

“I want to share with you the degree of alarm I feel on the issue of Japanese stiltgrass,” asserts Dana Wright, Land Stewardship Director.

“Stiltgrass is not like other invasives we have seen in Michigan, which spread relatively slowly and can be contained. Stiltgrass travels via water and deer, as easily as water itself.

“The six acres where we recently conducted a controlled burn evidenced a 75% cover of stiltgrass, and this has happened over a mere two years. I estimate in year one it was at 10% cover.

“Stiltgrass spreads quickly and completely. After it becomes established, it chokes out all native flora, and burning it becomes both dangerous and ineffective. The thatch (dead plant material from previous years) burns so hot that a burn would kill the surrounding trees.  What’s more, burning also stimulates the seeds of stiltgrass.

“I don’t tend to be dramatic, but in this case, I think it is warranted.  I believe this invasive has the power to completely ruin any woodlands it touches in a very short amount of time, which is why I feel it is very important for Legacy to participate in its eradication.

“We have four weeks until it goes to seed. We are working with Washtenaw County, the City of Ann Arbor, The Stewardship Network, and a few private citizens to build a plan to get stiltgrass under control.”
