The cartography and precise topology of more than six hundred stones throughout the entire boulder field were determined during summer. Then, two kinds of studies were undertaken. The first consisted of selecting 108 stones and analyzing the populations of bryophytes in terms of communities present and the position of species on the stones in relation to topology.

Abstract, the populations of bryophytes on a sandy boulder field on the slopes of Rû-des-Vaux, Le Moulin-des-Roches, in the forest of Rambouillet (Ile-de-France) were analyzed. This site is already recognized as one of the most interesting for its bryoflora. Paris: Flohic, 2000. Print. Turabian (6th ed. ravat, Michel. Le patrimoine des communes des Yvelines.

All species were recorded, and the principle populations were mapped. Transects were used to describe the position of each species in relation to the others. The second kind of study involved enumerating all species present at the level of the sandy boulder field.
