[APWG] Ecosystem restoration Straw effectiveness and weeds Re: Substitute local native ecotypes, for the exotics in the seed mixes?

I'm not sure why you're using straw. I know it has been popular (the custom) for years, but is only effective in a fairly narrow range of cases, and even in those it has its down-sides, in addition to being weedy.  Without specifics it is difficult to comment intelligently. How do you define (specify) "Michigan native ecotype?"

WT

Do you get "pop-outs" or other surficial slope failures in treated areas? Are soils compacted? Is it used on structural fills? How effective is it?

  Our big problem is the straw mulch. We require Michigan native genotype, but we are getting some disasterous results with weeds from the mulch. There are currently no certified weed-free providers in the state. Hopefully, we can work on that issue next.
