Summary — Growth responses of holm oak (Quercus ilex) to commercial thinning were studied in the Montseny Biosphere Reserve (northeast Spain), where selection thinning for firewood production is currently the dominant form of management in holm oak forests. Thinning significantly increased mean stem diameter increment by 83% over that of unthinned plots during the 6-9-yr period after thinning, and by 48% from 9-12 yr after thinning. Absolute diameter increment was positively correlated with initial diameter at 1.30 m from the ground (dbh) both in thinned and unthinned plots. Thinning increased growth in large trees more than in smaller trees. Relative diameter growth was negatively correlated with initial dbh. It is concluded that individual holm oak stems in previously coppiced stands respond vigourously to thinning, and still do so 6-9 yr after thinning. The growth response diminishes 9-12 yr after thinning due to canopy closure. However, absolute rates of stand growth, as well as basal area and stem biomass increments, were unaffected by thinning during these time intervals, an example of density compensation.canopy closure I Quercus ilex = holm oak I selection thinning I stand growth / tree growth Résumé — Effet d'une éclaircie commerciale sur la croissance d'un chêne vert (Quercus ilex L) dans les montagnes du Montseny (NE de l'Espagne). L'effet d'une éclaircie commerciale sur la croissance du chêne vert (Quercus ilex) a été étudié dans la réserve de la Biosphère du Montseny (NE Espagne). Dans cette région, l'éclaircie sélective pour la production du bois de chauffage est la forme la plus commune de gestion des forêts. L'éclaircie a augmenté l'accroissement de diamètre des tiges de 83% par rapport aux placettes non éclaircies entre 6 et 9 ans et de 48% entre 9 et 12 ans après le traitement. L'accroissement absolu de diamètre est corrélé positivement avec le diamètre initial à 1,30 m. Les gros arbres ont davantage augmenté leur croissance que les petits. L'accroissement relatif en diamètre est corrélé négativement avec le diamètre initial à 1,30 m. On peut conclure que les tiges du chêne vert dans le taillis étudié ont une réponse vigoureuse à l'éclaircie et que cette réponse se prolonge encore 6 à 9 ans après. L'effet sur la croissance diminue 9 à 12 ans après l'éclaircie par suite de la fermeture du couvert végétal. Cependant, les taux absolus d'accroissement du peuplement, ainsi que la croissance de la surface terrière et de la biomasse des tiges, ne sont pas affectés par l'éclaircie pendant ces intervalles de temps, ce qui constitue un exemple de compensation de la densité. fermeture de la couverture végétale / Quercus ilex = chêne vert / éclaircie sélective / accroissement du peuplement / croissance des tiges INTRODUCTION

“…Dissolution and leaching of soil minerals are regarded as soil formation processes in which chemical weathering plays an important role. Rodà et al (1990) reported similar increases in base cations and HCO 3 -from the deeper soil water to stream water and attributed this to chemical weathering. Ohrui and Mitchell (1996) pointed out that high rates of chemical weathering coupled with high temperature and precipitation are important characteristics of the Japanese watershed compared with Europe and northeastern USA.…”

We investigated the soil and soil water chemistry in abandoned terraced paddy fields (reed stand) and a thicket of deciduous broad-leaved trees (thicket stand) on the same slope in Sado Island, Japan. The soils gathered from these plots were incubated under different water conditions to examine the dynamics of dissolved ions. The organic carbon pool in the soil in the reed stand at the lower slope position was greater than the thicket stand at the middle slope position. The high concentration of base cations and an almost neutral pH of the soil water at the reed stand corresponded with the high exchangeable cation concentrations and base saturation in the soil. These results reflect the mineral-rich groundwater percolating down the slope, which may be produced by chemical weathering. An in situ sulfate reduction in the reed stand at deeper soil horizons was identified. The different water conditions in the incubated soils affected the soil pH(H 2 O), transformation of Fe, and dominant anions (NO 3 -, HCO 3 -, and SO 4 2-). These biogeochemical processes were more conspicuous in the reed stand at the lower slope position where the concentrations of organic matter and base cations were high. When the abandoned terraced paddy field is developed for the conservation of the Japanese crested ibis (Nipponia nippon) habitat in Sado Island, the reductive subsoil at the lower slope position should be kept waterlogged to limit sulfuric acid generation.
