I'm sure your local NRCS office can set you up with all kinds of info. Might even pay you some for doing it. Or maybe that's what you're doing already. For a good planting try to get a diverse a mix as possible. I'd stay away from switch grass if it was me - the native switch is ok but a lot of these cultivars that they sell will outcompete everything else you plant and you'll end up with solid switch and nothing else. Prairie cordgrass is good for wet sites. Then plant your drier site stuff(like big bluestem, indian grass, side oats gramma,little bluestem)in the spots that are on higher ground. If you plant a lot of flowers in the mix you'll attract a lot of insects which will provide food for baby turkeys and quail. Native flowers like new england aster, bottle gentian, blazing star, black-eyed susan, golden alexanders, yellow coneflower, sawtooth sunflower, cup plant, and wild bergamot grow well on wet sites.
