The species abundances were visually assessed with Braun-Blanquet scale values +, 1 ... 5 which are presented in numeric scale 1 ... 6 in the data set.

Shimwell (1971) used the data set to demonstrate the Braun-Blanquet tabular rearrangement method. He divided the data into three classification units marked as A, B and C, and removed one data set marked as X. The sample plots are named with consecutive numbers after a letter corresponding to these classes. The diagnostic taxa have a corresponding upper case letter after their name.
