The purpose of this study was twofold 1 to explore whether tillage has a lasting effect on soil compaction and soil moisture as well as on vegetation characteristics and 2 to analyse whether two distinct tillage treatments rotary plough vs. disc plough combined with vegetation control when necessary have the same effect on soil compaction soil moisture and plant establishment. Of the 29 species recorded 15 showed a significant recovery after soil loosening in the studied forest area. Interestingly different tillage treatments did not have the same influence on plant establishment. Treatment effects on soil structure and or moisture status can be considered as causing the observed growth response. ancient forest species forest understory soil compaction soil tillage soil loosening technique Résumé - Effets de traitements mécaniques du sol combines à un contrôle de la ronce et de la fougere aigle sur la restauration d un sous-bois degrade dans une ancienne hêtraie.
