| Résumé : |
"In two previous articles (Poore, 1955a, b) I have given a review of the methodology and practice of the Braun-Blanquet school of plant sociology, and a discussion of some of the problems which these raise. It has transpired that there is no proven theoretical basis for much of the system, which consists instead of a series of empirical treatments. Its justification, if indeed it is justified, lies in its application. Clearly, then, any fair verdict should be based on the results of practical trials rather than on theoretical grounds. Accordingly, a field study was undertaken during the summer of 1952 in the Breadalbane area of Perthshire. This region (and particularly the mountain part of it), was chosen for several reasons: I was already fairly familiar with the vegetation and flowering plants, and so could dispense with the primary survey which should precede a sociological study; much of the original and best Continental sociology had been carried out in the mountains of Central Europe and Scandinavia, and it was possible that mountain communities were the most amenable to this kind of treatment; the vegetation was relatively little affected by human interference; and the area was floristically rich by British standards, and might be expected to show species of high fidelity. My first concern was the clarification of problems of sociological technique, and not explanation of the ecology of the various communities. Naturally, however, the two cannot be divorced from one another; and, as the work proceeded, it became obvious that, quite apart from its value for the description of vegetation and possible use for collecting data for the classification of plant communities, the 'sociological ' technique was very useful for synecological studies in a way which is not indicated by its disciples. I believe this to be only a systematic application of the kind of observation and inference which every experienced field ecologist is accustomed to use, without, perhaps, always realizing their implications. But in this lies the great importance of the method." (source : auteur) |
