Info

In conclusion, the coniferous ecosystem has evoloved with and become adapted to and, in some ways, is dependent on brown rotted wood on and in soil profiles. Soil- wood performs similar functions as humus layers and in some instances exceeds the abilities of humus. Forest managers should therefore view woody residues as a manageable entity within existing concepts of resource management objectives. LITERATURE CITED Aho, P. E. 1974. Decay, In 0. P. Cramer (Tech.
