Cody, I have 5 seedlings in a pot on my deck now, waiting for dormant season to put them out. Foresters don't like sawtooth, because it is too small to make good sawtimber when it matures, which may be another reason that MO doesn't provide them. The species is a great acorn producer, and I don't think you will run any risk of harming the environment by planting them. They mature early, and produce so many acorns under the right conditions that you have to be careful walking under them.
When I was in forestry school in the 1970's they were touted as a great solution to the biological desert of a pine plantation, because they don't compete much with the pines, grow rapidly, mature early, and produce abundantly.
