Students at a college often took a shortcut between the library and the tennis courts across an area of open land. The area of open land was covered by a large number of plants of a variety of different species. Walking over this area many times damaged the plants by trampling. As a result, a shortcut path formed across the area of open land between the library and tennis courts. This path was approximately one metre wide.
Fig. 1.1 shows a map of the area.

Some students decided to investigate the effect of trampling on the biodiversity of plant species growing in the area of open land.
