[MAIPC] Microstegium and ferns

[Stephen Hiltner]

For what it's worth, I've been struck this year by how patches of fern
resist stiltgrass invasion. For instance, a ten foot wide roadside with
woods to the south and pavement to the north appeared to be 100% stiltgrass
except for a small patch of sensitive fern, which looked to be free of
stiltgrass altogether.
