Three structurally different situations are analysed: close after silvicultural intervention, in the middle of two interventions and before cutting. Therefore 19 plots were selected in the area, obtaining dasometric and qualitative values in order to characterise traditional management. Positive tree selection of traditional management is proved, as well as a high percentage of trees of a good stem quality, particularly at dominant layer (33%). Liocourt constant values in these stands were determined: they change for every described situation (2.8-1.6; 1.2-2.6; 1.7-2.8). With these values, 45 types of uneven evergreen oak forests were modelized modifying initial density (900, 1100 and 1200 stems/ha) and q values (DC10: 2.5; 2.7; 2.8; DC&amp;gt;15: 1.5; 1.6; 1.7; 1.8; 1.9), while keeping maximum initial diameter (25 cm) and rotation (30 years). The comparison between these models don&amp;rsquo;t show significant differences independent from initial values. Using mean values obtained from the sample plots, a preliminary optimal equilibrium curve for uneven oak-coppice stands has been developed. Finally structural differences between those stands, traditional ones of Central Europe and uneven Pinus nigra forests of Pyrenees are upbright.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Bacilieri, R</style></author><author><style face="normal" font="default" size="100%">Bouchet, M A</style></author><author><style face="normal" font="default" size="100%">Bran, D</style></author><author><style face="normal" font="default" size="100%">Grandjanny, M</style></author><author><style face="normal" font="default" size="100%">Maistre, M</style></author><author><style face="normal" font="default" size="100%">Perret, P</style></author><author><style face="normal" font="default" size="100%">Romane, F</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">NATURAL GERMINATION AS RESILIENCE COMPONENT IN MEDITERRANEAN COPPICE STANDS OF CASTANEA-SATIVA MILL AND QUERCUS-ILEX L</style></title><secondary-title><style face="normal" font="default" size="100%">ACTA OECOLOGICA-INTERNATIONAL JOURNAL OF ECOLOGY</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">ABANDONED LAND</style></keyword><keyword><style  face="normal" font="default" size="100%">CASTANEA-SATIVA MILL</style></keyword><keyword><style  face="normal" font="default" size="100%">Coppice stands</style></keyword><keyword><style  face="normal" font="default" size="100%">germination</style></keyword><keyword><style  face="normal" font="default" size="100%">Mediterranean climate</style></keyword><keyword><style  face="normal" font="default" size="100%">Regeneration</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1994</style></year></dates><publisher><style face="normal" font="default" size="100%">GAUTHIER-VILLARS</style></publisher><pub-location><style face="normal" font="default" size="100%">DEPT UNIV PROFESSIONNEL REVUES SCIENTIFIQUES TECHNIQUE 11 RUE GOSSIN, F-92543 MONTROUGE, FRANCE</style></pub-location><volume><style face="normal" font="default" size="100%">15</style></volume><pages><style face="normal" font="default" size="100%">417-429</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">In the Mediterranean basin, most of the present forests derive from original forests where the dominant species was different from the present one. These changes are largely due to human activities reflecting millenia of management and, often, overexploitation. In southern France, for example, palaeoecologists believe that the original malacophyllous deciduous forest of downy oak (Quercus pubescens) was replaced by a sclerophyllous evergreen holm oak (Quercus ilex) coppice in the driest areas, and chestnut (Castanea sativa) orchards or coppices in the `'wettest'' areas. However, for the last several decades, exploitation of these coppice stands has been decreasing. In this study, we addressed the question of the resilience of these managed ecosystems in the fact of changing management schemes, and to determine appropriate strategies and criteria of sustainable development. We present some aspects of the auto-succession after clearcutting of holm oak coppice stands and aspects of the natural regeneration of 4 species (Q. ilex, Q. pubescens, C. sativa, and P. pinaster). The consequences of the contrasted life history strategies are compared to estimate the future of these coppices.</style></abstract></record></records></xml>
