Brettski, I have some experience with prairie plants. Unfortunately, I think you will be fighting a loosing battle. The trees will invade this small prairie very quickly. You will have to mow this prairie every year and burning will also help. Still, the trees will shade much of this prairie and prairie plants do very poorly with shade.
Bruce Condello, can you add some of your experiences with your CRP bottom land? This grassland was completely overtaken by trees.
Bring up these concerns to your local biologist and ask their advice. I love prairies. After you have visited with your local biologist, post their thoughts and I can add some ideas for you to consider.
