[MAIPC] Another stiltgrass question

[Randall, Johnny]

Heidi and others. I think there are too many variables to consider on stiltgrass invasion and persistence to answer your questions. Removal in areas where it is infrequently (re)introduced (outside of floodways) is a viable solution. It’s a C-4 grass which gives it the physiological/anatomical potential to persist in uplands unless it is removed before going to seed.

Before stiltgrass has moved in too fast into my park from elsewhere, I found if I removed it all for 3 years, by the 4th year I was finally happy. Marc

I know there have been several discussions about stiltgrass and I apologize if I have missed some information. But, I am trying to figure out the difference between my volunteer site and other volunteer’s success in removing stiltgrass.

Besides shade, soil characteristics (pH, moisture, etc. ), and deer browsing has anyone looked into the  habitat restoration plan or the native seed bank to see if there is an effect upon % of stiltgrass seeds that germinate, survival rate of seeds, and growth rate of the stiltgrass?
 I am specifically wondering about the following items:
1) The number of native seeds, not type of seeds.
2) the process of invasive removal - either removing all invasive plants in one year (repeating as needed) or a staging process over several years - bushes, vines, forbs, other graminoids, then stiltgrass.
3) Planting native plants (plugs and quart sized plants) vs  doing nothing vs using a seed mix.

I appreciate my guidance people can provide.
