For those not familiar with the acronyms, “CRP” is the Conservation Reserve Program.
The whole purpose of the CRP program is to reduce erosion and provide habitat for wildlife. Usually CRP acres cannot be “harvested” or otherwise used, they are to be planted with a combination of native and beneficial plants and noxious weeds have to be kept suppressed or controlled.
But in extreme conditions haying and grazing of CRP acres can be allowed, usually on a county-by-county basis. As of July 23, 48 out of the 56 counties in Montana were considered to be unusually dry enough that CRP haying and grazing is allowed.
See the July 23rd USDA bulletin for the Montana Farm Service Agency for more details.
