摘要: Dead wood is an important structure for conservation purposes and maintaining biodiversity. In this context, snags were studied under different conditions in silver fir ancient forests of the southern French Alps. The impact management status developmental phases estimated on both quantity quality material. SDT volume averaged 64.6 +/- 19.8 m(3) B ha(-1) 15.8 6.0 unmanaged managed forests, respectively. varied according to point silvicultural cycle silvigenesis ranging from 4.3 3.4 early aggradation phase 202.3 48.6 degradation forest.
