THE VEGETATION OF CONNECTICUT 

 III. Plant Societies on Uplands* 



By George E. Nichols 



In the first paper of this series the writer undertook to point 

 out and in a measure to account for certain of the broader features 

 of the vegetation of Connecticut. In the second an account 

 is given of the virgin forests. In the present and subsequent 

 papers attention will be devoted primarily to the study of plant 

 societies and their relationship both to one another and to 

 environment. Numerous writers during the past few years have 

 dealt with this phase of vegetation in other parts of the country, 

 but so far as published records show very little work of this 

 nature seems to have been accomplished in southern New England. 

 Since it is desired that this series of studies may serve as a starting- 

 point for further investigations, both extensive and intensive, it 

 has seemed advisable to treat the subject matter more or less 

 comprehensively, drawing freely upon the observations of other 

 workers in the same field of study. 



The scheme of classification which in a general way underlies 

 the writer's treatment of the plant societies of Connecticut is 

 the one originated some years ago by Cowles.f This classi- 

 fication "attempts to relate plant societies not only to water, but 

 also to soil, and more especially to the physiography." The 

 fundamental concept of the scheme is that "each particular
