So far we don't mow anything. That's why we're blasting them with gly and trying to replace the grass with clover and rye. We're trying to figure out a way to get/store/maintain a brush hog up there. On the plots, we're keeping the perennials out for now until we can solve that riddle. Otherwise, this year, we had rye in from last year and did a burn down mid may and then followed with a good roughing-up with the harrow. We've gotta be careful because we've got moderately sandy soil with an OM of about 4%. So 1" deep is about all we'll likely ever go, and probably not at all with the easier to germinate crops.
For the bears, as cool as they are to look at, I would like to hunt them as hard as we can. It won't be more than another couple years and we'll have saplings starting to hold new fruit, and I'm not looking forward to seeing them ripped to the ground. Plus I'd love to try canning some bear meat.
