The Human Footprint in the West The human footprint map focuses on shrubland ecosystems and combines models of habitat use by synanthropic predators (“top-down” effects) and the risk of invasive plant presence (“bottom-up” effects) to estimate the total influence of human activities. Humans have dramatically altered wildlands in the western United States over the past 100 years by using these lands and the resources they provide. Anthropogenic changes to the landscape, such as urban expansion, construction of roads, power lines, and other networks and land uses necessary to maintain human populations influence the number and kinds of plants and wildlife that remain. We developed the map of the human footprint for the western United States from...
