The volume of dead wood averaged 15 m3/ha. Downed woody debris, stumps and snags represented 81 % , 11 % and 8 % of this volume, respectively. Pieces of downed woody debris were equally distributed between fine and coarse woody debris however large pieces (diameter ≥20 cm) were scarce. The dead wood was mainly from anthropogenic origin (77 % ) and its volume significantly increased with stand productivity. The pattern of dead wood accumulation along the forestry cycle showed a convex shape with a peak in stands of ca. 30-year-old, after the third thinning. The dynamics was successfully predicted for downed woody debris (r = 0.47, P < 0.001) and for stumps (r = 0.45, P < 0.001) by the model combining inputs from thinnings and loss with time. This model may help to predict the effect of alternative forestry practices on dead wood accumulation by forest managers or nature conservationists in similar pine forest plantations.
