From the UI official home page of Chancellor Robert Jones: "A Land Acknowledgement is a formal statement that recognizes and respects Native peoples as traditional guardians of lands and the enduring relationship that exists between Native peoples and their traditional territories." For more details, including the names of the peoples on whose land the University resides, see Official UI Land Acknowledgement. This statement is read at the opening meeting of every UI Senate year.
