In order to interpret the 12,000 vegetation survey samples taken in the forests of Canton Vaud, half of which were placed in a systematic grid, it was necessary to develop a complex dichotomous key. This obliged the phytosociologist to specify the criteria identifying each plant community. The most recent version of the automatic dichotomous key provided satisfying results in 90% of all cases, though an expert appraisal can not be entirely dispensed with. A certain need for further improvements on the key was identified.
