  abstract = {{T}he aim of this paper is to contribute to the understanding of the changes in plant cover after the recent glacier retreat, in an alpine environment. {T}he selected study site in {S}avoie in the {F}rench {A}lps (2502-2509m asl), belonging to the {E}uropean network {N}atura 2000, provides favourable conditions for the study due to the flat glacier foreland, where the glacier did not advance since the {L}ittle {I}ce {A}ge. {D}ata collected from 110 botanical plots were correlated with dated glacial and proglacial landforms. {S}pecies diversity has been analysed using the {S}hannon-{W}eaver index, the {G}rime classification, and the uncommon species described in the {E}uropean list of {N}atura 2000 {E}uropean {N}etwork. {C}lassical and multivariate analyses have been made to determine the impact of the glacial retreat on the biodiversity variation. {W}e show that the changes in species richness and vegetation cover were related to the distance from the glacier front. {T}he biodiversity index was less than 2.5 near the glacier but above 4 at the furthest point. {T}he highest plant diversity, however, was observed at an intermediate position, where competitive and pioneer plants were equally represented in the field. {T}his location, concurrently, showed the highest heterogeneity in the activity of periglacial processes. {I}t seems that the most heterogeneous and disturbed soils, due to inherited deposits and currently active periglacial processes, are responsible for an increase in biodiversity.},
