The points selected for study are called stations. Stations are subdivided on the basis of plant and animal habitats into substations. The sub- stations may represent either formations or divisions of formations. For example, a station like Wolf Lake may be divided into sandy shore substation, vegetation of open-water substation, and embayment substation. 2. ENUMERATION OF STATIONS—GUIDE In the study at hand we have made use of a large number of stations which are enumerated below and are referred to in the text. The list.
