I've been planting small pockets of cover the last couple years - usually consisting of 10-12 Eastern Red Cedar plugs and 12-14 shrubs - usually the one's noted above (RDO only if in a wetter area) and mix in a few other honeysuckle, currents, false indigo, cranberry, etc. All about variety. Hopefully in 10 years if 1/2 of the trees make it to maturity, I'll have some nice little bedding areas where the deer won't have to move much to get a snack.
Look for shrubs you think will benefit the deer, but that you don't see around your property currently.
I have a ton of native chokecherries and some hawthorns, a few plums, but really none of the others noted above.
