Most recolonization projects are geared towards land determination being returned to indigenous groups, an example of this type of determination being violated is the long history of pipelines being brought through or near Native land within this century, as well as mineral/oil rights being fucked over as well and thereby financial proceeds drawn away that would support the community (there's a reason why so many Tribal lands push for casinos is due to the income and jobs that supports the community and creates a tourist economy that is distinctly different from those commonly seen outside of tribal areas (i.e. shitty jobs, worker exploitation, money going towards some out of state LLC). Still though this is one type of interpretation but none that I've seen so far are in the "drive everyone the fuck away from us" and is instead more towards "hey can we not have settler waste shit placed near us or have our resources taken without our knowledge/consent?". Additionally a lot of land near most contested indigenous grounds has been dismantled into larger big AG projects so if that land was taken back it's mainly being taken and redistributed from corporate collectives i.e. fuck Monsanto etc.
