if you cut brome yearly, it wouldnt be matted or crushed down during snow.
i cut hay every year, i will leave strips in fields for hunting.. but i will cut one side one year and leave the other side then cut the other side the next year and leave the other strip alone... this gives brome grass a strong growth and it does withstand snow. it does even collect snow to catch moisture. this will give the standing strip more brome grass to grow thicker. works every year and no problem. if you leave brome grass grow year after year... then yes, it does get matted and pushed down that it looks so flat its no use anymore. if you get a farmer to cut one side this year and then cut the otherside next year.. you'll see better results.
