The landowner needs to provide a proposed seed mix and pounds per acre it will be installed. Prairie Moon Nursery and Prairie Restoration Nursery are good sources for native seed mixes for upland areas. For this area of Orono I would recommend a mesic prairie mix. It appears from the write-up that he is proposing not to excavate and remove the turf but till the top three inches instead. If this is the case the grass should first be sprayed and killed with a water-soluble herbicide like gyphosate (Roundup, Rodeo, etc.). If he is completing removing the turf grass including roots by excavation spraying with a herbicide will not be necessary. He needs to verify in the write-up what approach he is going to use. I would recommend that he not limit himself to hand pulling buckthorn only. Some of the buckthorn is larger and he may want to follow the approach for large buckthorn from the DNR so he is not limited(see attached). If he wants to use the attached approach he should reference it and provide it as an attachment with his submittal.
