ELH...I said native shrubs.. I've heard of areas where oaks, maples, pines, aspens, etc. cannot regenerate in WI and elsewhere, but have never had a problem with that on either place I owned or managed there.
For the record, prickly ash, box elder, and burdock are native.
dipshit...the reason cedar regenerates in many parts of WI is that there is so many of them. Deer can't eat 'em all. When you attempt to introduce them in an area where none exist, they are more likely to be targeted due to the "unique" factor.
