“…The optimal P N values (17.1 ± 2.4 µmol m -2 s -1 ) corresponding to favourable air temperature (in the range 19-20°C) for this species were in agreement with those measured by Deweirdt and Carlier [16] and Pontailler et al [44], and they were higher than those monitored by Gomes-Laranjo et al [18] and Proietti et al [46]. The high P N rates could be primarily attributed to the favourable climatic conditions and soil physical-chemical characteristics: the water content and SOM never limitant, and the sand-silty and acid soil favour chestnut growth in the Park, according to the results of Bernetti [5], Leonardi et al [34] and Rubio and Escudero [54]. The higher SOM and N t contents in OC than in YC was due to the higher amount of soil litter falling in OC over the years (data not shown), even if the C/N ratio value close to 11 in both YC and OC pointed out the good state of mineralization and humification processes in both stands.…”

“…LAI between 10 and 17 years, corresponding to the highest values, might be considered a good estimator of the maximum biomass accumulation [54]. LAI was the most important factor influencing C assimilation and water loss in plant communities [21,28,39,60] and it might provide an indicator of potential productivity in response to changing factor [23,25,26,42].…”

“…Soil samples were air dried at room temperature for about 1 month and then passed through 2 mm sieve [54]; pH in H 2 O was measured with a glass electrode in a suspension of soil in deionized water; N t content (%) was determined by Kjeldahl method, and SOM content (%) was determined according to Walkley [64]. Carbon nitrogen ratio (C/N) was calculated.…”

“…Knowledge of quantitative relationships between stand structure and species composition may contribute to more advanced indirect estimations of stand carbon balance and plant productivity [29,53,65]. Forest management determines unavoidable changes in forest structure, interfering with self-regulating processes and productivity, and having considerable influence on forest stability [32,54,61]. Since the primary source of structural and physiological variability among managed forest stands is determined by differences in rotation stage (time since harvest) [31], understanding the functional status of a managed forest requires an accurate characterization of the different stage of development.…”

-Coppices of Castanea sativa Miller (1,5,7,10,12,17,23,26, and 30 years old stands) were investigated. Total basal area (BA) ranged from 4.9 ± 1.9 m 2 ha -1 (1 year old stands) to 41.0 ± 2.3 m 2 ha -1 (30 years old stands), and Leaf Area Index (LAI) from 0.18 ± 0.08 m 2 m -2 (1 year old stands) to 5.00 ± 0.22 m 2 m -2 (12 years old stands). Morphological and physiological leaf traits were analysed in 5 (YC) and 23 years old stands (OC) to point out the functional responses to clearing impact. The results pointed out the high productivity of C. sativa in the Park, due to favourable climatic and soil conditions. Significant differences of morpho-physiological leaf traits between YC and OC stands were observed during the last period of the vegetative cycle; it could be due to the higher efficiency in resource use of YC leaves than OC.

-In the Cevennes, many abandoned chestnut groves have been turned into coppice stands. It was previously shown that plant diversity decreases after abandonment. Nevertheless, we propose that logging could be an effective means to maintain plant diversity. The main objective of the present study was to analyze plant diversity changes after clear-cutting and thinning of a chestnut coppice stand as compared to a nearby uncut stand. We hypothesized that rapid chestnut growth, and consequently reestablishment of a closed canopy, would lead to a decrease in species richness. In fact, herbaceous plant species richness showed a large but only temporary increase after logging. A surprising result was the high percentage of hemicryptophytes observed after logging. Generally, therophytes are the first invaders of open areas. Hemicryptophytes occurring after logging were common species and no rare species was found, there or in the uncut area. Moreover, the increase of species richness concerned especially anemochorous plants. It appeared that one possibility to preserve plant diversity, at the landscape scale, could be to maintain a mosaic of chestnut groves, abandoned chestnut groves and coppice stands. plant diversity / life form / dispersal mode / leaf area index / management Résumé -Évolution sur le long terme de la composition végétale de la strate herbacée après coupe forestière de taillis de châtaignier dans les Cévennes dans le sud de la France. Dans les Cévennes, de nombreux vergers de châtaigniers abandonnés sont transformés en taillis. Il a été clairement montré que la diversité végétale diminue après abandon. Toutefois, la coupe forestière pourrait être une solution pour maintenir un certain niveau de diversité. L'objectif de l'étude était d'analyser les changements de la diversité végétale après coupe rase et éclaircie d'un taillis de châtaignier et de comparer avec un taillis voisin non coupé. La richesse spécifique montre une forte augmentation après coupe forestière mais seulement temporaire. Un résultat inattendu a été le pourcentage élevé d'hémicryptophytes observé après coupe rase et éclaircie. Généralement, les thérophytes sont les premiers colonisateurs de milieux ouverts. Les hémicryptophytes installées après coupe sont des espèces communes, aucune espèce remarquable n'a été rencontrée tout comme dans le peuplement non coupé. De plus, l'augmentation de la richesse spécifique concerne essentiellement des espèces anémochores. Il semble qu'une possibilité pour préserver la diversité des plantes, à l'échelle du paysage, serait le maintien d'une mosaïque de vergers de châtaignier entretenus, de vergers de châtaigniers abandonnés et de taillis.diversité végétale / type biologique / mode dissémination / surface foliaire / gestion

The short-term impact of coppice-with-standards management on soil in a Mediterranean holm oak forest was assessed to contribute to address appropriate recommendations to minimize possible negative effects of the silvicultural practices. For this purpose, soil surface features and topsoil properties were investigated in two representative areas located in a public forest in southwest Sardinia (Italy) and coppiced in the periods November 2012-March 2013 and November 2011-March 2012, respectively. Regardless of differences in soils and slope gradient, the same management, in terms of final density of trees standing after the clear-cut and accumulation of brushwood in strips along the maximum slope gradient, was applied in both areas. Field observations and laboratory data highlighted the disturbances caused to the soil by the silvicultural practices in the stands when compared with the undisturbed stands. These disturbances involved the almost complete removal of organic horizons, with consequent negative impact on organic carbon content, and the activation of erosion processes, mostly related to rainsplash erosion. Although soil mobilization locally largely exceeded the tolerable erosion rates, no extreme rainfall events occurred after the coppicing to produce critical situations at the catchment level. The adjustment of the final density of trees standing after the clear-cut in relation to soil properties, slope gradient and the possibility of extreme rainfall events, a different brushwood management and the restriction to the passage of wild animals would have strongly reduced the negative impacts on soils.
