An example of erosion on campus is the worn paths students make as they find the shortest distance between campus buildings. In fact on some campuses, sidewalks to new buildings are not constructed until the student paths emerge. Leftovers are traces represented by objects not consumed in the behavior. Trash and litter are the most common examples. On campus these leftover traces can be used in locating new trash receptacles.
Leftovers can also become associated with particular campus groups.
Many campus spaces have been designed in such a manner that they are never used by people on campus. Campus adaptation for use would include renovations, expansions, and other changes or improvements. The addition of a new lighting system on campus is an environmental adaptation to increasing campus crime. Changing an open space area to a parking lot could signify an adaptation to an increase in commuting students. The Greek letters on fraternity and sorority houses is a clear example.
