The bee thing is fascinating. My hunting land is in an area far away from farming and urbanites. I've just begun to alter the natural landscape with a chainsaw, mower, and seeding. I counted native flowers this year, and got upwards of 30 or so on my land if I remember right. In my plot that I converted to white clover and a ton of other things (including barley), the bee activity out there was almost frightening. And there were all kinds big, little, hairy, smooth, black, yellow etc.
I tried digging on the edge of my plot with a mini excavator, and hit a ground nest on the first scoop in two spots. I quit while I was ahead.
