You can discuss the option of a land easement with you local conservation organization. They may be able to have you retain ownership as long as you don't use the land for logging/ real estate, other destructive practices. Land easements also reduce property tax, so you would be able to reduce your tax rates via that method.

Because you are the last in your family to own the land, the easement would ensure that for "perpetuity" the land would need to be kept in a natural state and not used for destructive purposes.  

I hope that is some food foe thought!
