There is one solution to finding out territory problems and it help with everything, we just need to keep our promises for once. We need to give them enough land for them to be able to sustain their lifestyle, but this time all settlers must stay out of it. If we keep out of that land that solves more than one problem. In all reality that will solve all problems. If we give them the land they need and keep our promises and let them have that land to themselves there won’t be any problems with natives and settlers clashing. The hard part is going to be able to tell where the native land starts and ends without a fence or something. No one wants to be fenced in and quite frankly no one wants to be fenced out. So my idea would be to put up signs surrounding the land. We would space them out a half mile from each other so they would be hard to miss of course, but if that doesn’t work we might have no choice to resort to fences for both settlers and natives safety.
