This map is an example of the kind of large-area mapping which is possible with the method outlined in this GUIDE. It is based on data gathered in 1972 by six Oregon State University students, Steve Carpenter, Bob Denison, Andy Merzenich, Dave Newman, Mark Scherzingei and Chris Shonnard, during a Student Originated Studies project supported by the National Science Foundation. Data on lichens from approximately 170 sites were obtained using a format similar to Form #l found in this GUIDE. The data were then plotted on a map of the Willamette Valley. The map is based on a slightly different scale of lichen classes than the one described in this GUIDE: the map scale contains fewer species of lichens and does not recognize a "Class 0."
An updated version of this map will be made using data from readers who return copies of Form #l with data on sites which the sampled.
