Historical ecology is the study of how people and their environments have interacted in the past. It looks for clues about how people used certain areas in the past, and how this may have influenced the natural environment. One way to do this is by looking at the type of plants and animals that lived in an area before humans arrived, and seeing how those have changed over time. It can also involve looking at stories and records about the past and seeing how people used the environment then. All together, historical ecology can help us to better understand how humans and the environment have been connected throughout history.
