| description | Dead wood is an important structure for conservation purposes and for maintaining biodiversity. In this context, snags were studied under different conditions in silver fir ancient forests of the southern French Alps. The impact of management status and developmental phases were estimated on both quantity and quality of this material. SDT volume averaged 64.6 ± 19.8 m3*ha-1 and 15.8 ± 6.0 m3*ha-1 in unmanaged and managed ancient forests, respectively. SDT volume varied according to the point in the silvicultural cycle and silvigenesis cycle ranging from 4.3 ± 3.4 m3*ha-1 in early aggradation phase of managed forests to 202.3 ± 48.6 m3*ha-1 in degradation phase of unmanaged forest. Large SDT significantly belonged to the degradation phase of unmanaged forests. Our research showed that SDT density in this ancient forests was mainly governed by natural processes. An average of 9 large SDT per ha has been proposed to preserve the ecological processes.
Gestion du bois mort sur pied : comparaison entre forêts anciennes gérées et subnaturelles des Alpes du Sud françaises. La quantité de bois mort est un enjeu important dans la conservation et le maintien de la biodiversité forestière. Dans ce contexte, les bois morts sur pied ont été étudiés dans des hêtraies-sapinières anciennes des Alpes du Sud françaises. L'impact du mode de gestion et des différentes phases du cycle sylvicultural et de la mosaïque sylvatique a été estimé. Le volume moyen de bois mort sur pied atteint 64,6 ± 19,8 m3*ha-1 dans les forêts anciennes inexploitées, alors qu'il n'est que de 15,8 ± 6,0 m3*ha-1 dans les forêts exploitées. Ce volume moyen varie selon la mosaïque sylvatique, passant de 4,3 ± 3,4 m3*ha-1 dans la jeune phase d'aggradation des forêts anciennes exploitées à 202,3 ± 48,6 m3*ha-1 dans la phase de sénescence des forêts anciennes inexploitées. Cette dernière contient significativement les gros bois sec sur pied (DBH > 43 cm). Nos résultats montrent que dans ces écosystèmes montagnards, la disponibilité en bois mort sur pied, est due essentiellement aux fortes contraintes environnementales en présence. |
