AN ECOLOGICAL CLASSIFICATION OF THE VEGETATION 
OF CEDAR POINT. 
By Otto E. Jennings. 
The peninsula of Cedar Point, forming for seven miles a 
narrow barrier between the marshes and open waters of San¬ 
dusky Bay on the west and Lake Erie on the east, is probablv 
by far the best place in Ohio for the study of ecology, either 
with respect to the adaptation of the plants to their environ¬ 
ment, or to the aggregation of different species of plants into 
associations of various kinds, or the successional development 
of these various associations. 
During the summer months of 1903 the writer, acting in 
capacity of Assistant to Dr. W. A. Kellerman, devoted his entire 
time to the preparation of a herbarium of the flora of Cedar 
Point and, in 1905, while acting as Instructor at the Lake Labor¬ 
atory, the peninsula was again thoroughly explored and consid¬ 
erable study was made of the ecological phases of the subject. 
* In 1906 and again in 1907 several days were spent on the penin¬ 
sula, mainly in taking notes and in perfecting previous classifica¬ 
tions of the vegetation, and it is believed that a fairly correct 
general ecological classification can now be presented of the vege¬ 
tation of Cedar Point. 1 
This rather brief reconnaissance is given in the hope that it 
may be of use to other students of the flora of Cedar Point, serv¬ 
ing as a basis for future more detailed and comprehensive work 
along ecological lines. Excellent opportunities are presented at 
Cedar Point for exact instrumental studies of the various habi¬ 
tats and it is to be hoped that the future may see this accom¬ 
plished. 
1. The author would here take the opportunity of gratefully acknowl¬ 
edging the various courtesies extended to him by Prof. Herbert Osborn, 
Director of the Ohio State University Lake Laboratory, and also the 
assistance rendered by Mrs. O. E. Jennings in the preparation of the 
illustrations for this article.
