Iowa Public Land - Forever?

[cyclonenation10]

This may be a really stupid question, but I was wondering if public lands in Iowa (not IHAP) but actual state/county owned and managed wildlife areas, prairies, wetlands, etc. we’re guaranteed to stay that way forever? Meaning, is it written into law, contract, or something, that once a public hunting area is established that it will remain that way into perpetuity? Is there anything that can ever reverse that (for example, state/county sells land back to farmer/developer) ? I was just thinking about this, and wondering if we could ever have less acres than we do now, or is the number never going to get smaller and only bigger potentially?

Land swaps are done, we traded some to the DNR years ago for some state owned land that bordered our farm.

There is occasionally talk of selling some very valuable land on West Lake Okoboji the state owns.
