“…However, this difference cannot explain the observed variations in plant composition and soil properties. On limestone plateaus of northeastern France, silt deposits are usually associated with more acid soils and less diverse and nitrophilous plant communities (Becker 1979), an opposite trend to the one we are reporting here. Moreover, the major textural jump occurs between enclosures and nearby terraces (Table 1), while the plant community discontinuity is between nearby and remote terraces ( Table 2).…”

In western Europe, forest area has been expanding rapidly since the 19th century, mainly on former agricultural land. Previous studies show that plant diversity differs between these recent forests and ancient forests that were already forested at the time of first national cadastral surveys, around 1800. Here, we investigated the duration of such agricultural aftereffects. In northeastern France, large areas were deforested during the Roman occupation and thereafter abandoned to forest. In one such forest that was farmed during the period AD 50-250, we show that species richness and plant communities vary according to the intensity of former agriculture. These variations are linked to longterm changes of chemical and structural soil properties. Hence, we suggest that such effects of past agricultural land use on forest biodiversity may be irreversible on an historical time scale.

“…On limestone plateaus of northeastern France, silt deposits are usually associated with more acid soils and less diverse and nitrophilous plant communities (Becker 1979), an opposite trend to the one we are reporting here. However, the strength of the relationship between ancient land use and present plant diversity patterns makes it difficult to find any other explanatory factor.…”

“…are also found to explain variability in radial growth and wood density. However, in the related studies, factors such as climate, water and nutrients were not distinguished (Bergès et al, 2008), and site condition variability was largely not accounted for; for instance, in most cases, extreme site conditions were not sampled or were undersampled (e.g., Polge and Keller, 1973;Becker, 1979;Guilley et al, 2004). In our study, for the beech trees, the ring width in the treatment plots (i.e., RHRL) explains less than 1% of the wood density reduction in the newly formed rings; to the remaining variation (of the 2.56% observed) comes from the treatment itself (after the ring width effect is removed).…”

Background: Increased exportation of harvest residues from forests, to mitigate excessive demand for woody biomass, have reportedly diminished soil mineral resources and may lead to degraded tree nutrition and tree growth. However, as nutrients become less available in the soil, the remobilization of nutrients in biomass tissues (plant internal cycling) helps sustain tree nutrition. Our study aims to quantify the impact of Removing Harvest Residues and Litter (RHRL) during five years on tree growth, wood density and stem wood nutrient concentrations in young beech and oak forest stands.Result: Our study found that, RHRL significantly decreased the tree growth ring width, by 14%, and wood density, by 3%, in beech trees, in the near bark rings. RHRL also significantly reduced the nutrient concentration in the near bark and near pith area of both species. Mg, Na and S were found lower by 44%, 76% and 56%, respectively, in the near bark area of beech trees, and K, Ca, Mg, Na, S and Fe were lower by 20%, 25%, 41%, 48%, 41% and 16%, respectively, in the near bark area of oak trees. K and Mg concentrations decreased more strongly in the near pith area compared to the near bark area suggesting internal translocation of these two elements. Conclusion: In beech trees, wood density proved to be an important factor while quantifying the effect of removing harvest residuals on the tree growth and biomass. Soil nutrient loss intensified the remobilization of nutrients contained in older tree rings (close to the pith) towards newly formed rings (close to bark). In our study, in beech trees, K was found to be the most recycled major nutrient. These results demonstrate the potential of such analysis for providing valuable insight into the effect of RHRL in premature stands on the physiological adaptive strategies of trees and an indication of soil fertility and acidity status.
