Boundaries in landscape history are ideas about how people used and interacted with the land around them in the past. People have been living in different areas and on different lands since ancient times, and different communities have used the land differently. For example, some communities may have used an area more for growing food and taking care of animals, while others may have used the same land more for hunting and gathering resources. By looking at the different ways people used the land and the boundaries they set up between those different uses, we can better understand the history of the landscape and how people used it in the past.
