Do you have recommendations on what plants and/or trees to plant that would be most beneficial for the bees?
I know someone that is currently experimenting with Sainfoin on some remote land in Idaho, it is supposed to be very bee friendly since it blooms from May through July(or even later) and can be harvested or grazed by livestock.
