I really like what you have planned there! Not sure what program or requirements the program might have, but inside of the bigger food plot (into the field), if allowed, a larger mono block of switch grass. That switch grass will be the great winter cover, easy access to the food and good escape cover when feeding. All the habitat will protect the switch grass cover from blowing-in with snow with your prevailing NW winds. Great choice on the shrubs listed, I plant ones that will provide both cover and food (a nut or berry). I think you will want to space the shrubs at least 8 feet between the rows, I think ours were 12 feet, but after 7-8 years we can still drive and UTV between them, except next to plums. You might consider spreading some white clover seed between the rows, it is short, flowers to bring bugs, easy for chicks to navigate, suppresses weeds. In ours (NW IA) the wild plums do the best, they do sucker and will get thick, which I like. Talk with your local PF guys, (and/or county conservation) they might have a tree planter and may have man-power to help. They might even provide financial help. If you have access or can find a someone with a machine to lay-down the plastic or fabric mat consider that. In the first 3-4 years trying to keep the unwanted vegetation down with be quite overwhelming. A cheaper option would be to use a mix of Pendulum & Prowl. I set up a single nozzle on our Gator to a apply a band on each side of the shrub rows to suppress the weeds. If the power company is doing tree trimming around the power lines in a town near your ground, I found they are very willing to dump their mulch at your site (ours was just over 8 miles from town). This should be a fun habitat project for sure!! Oh yah, maybe the most important thing for success...pray for rain! Keep the thread alive as you progress on this....love this stuff!
PS. When the time comes for the seed of the CRP, look for a mix (or request one) without the rye grasses with the mean seeds. A mix with forbs (wild flowers) might be better for pheasants, but if you want to be able to easily control weeds (thistles) on a large scale, you might stick with just grasses...we went with the forbs, it is a pheasant deal for us...I hand spray the thistles.
