Maggi,
The Eurasian grasses, as we call them, are a huge problem. Our native bunch grasses stay "green" all year and thus do not burn as easily as the Eurasian grasses. Sadly now, one rarely sees the native bunch grasses. My wife and I are making an effort to reestablish our native bunch grasses here at the farm. It is very slow going as the Eurasian grasses are very aggressive.
Thanks! It is all very interesting.
