Indiana has a great program if you are willing to keep land in wildlife habitat forever and manage it properly. We have the Classified Forest and Wildlands Program, which I just put a small parcel in (15 acres) to get my feet wet and make sure that I understand it properly. The assessment on the land goes to $1 per acre. I was planning to put my whole place in the program when I retire, but an incompetent tax assessor reclassified the land as "excess residential". I will need to go to court for this years taxes, but it is really an open and shut case since nearly identical cases have recently gone through the courts with the landowners universally winning.
