Keywords: large woody debris, mountain streams, wood deposition, geosystem, ecosystem

Summary: The paper reports on results from the studies concerning trees and shrubs fallen into mountain streams and rivers. Fallen trees, shrubs and their larger fragments are termed large woody debris. Logs, shrubs and whole trees, jams and stumps are the types of large wood accumulations found in channels. Wood is delivered to the channels of mountain streams and rivers as a result of snag disintegration, blowdown of trees and bank cutting, by avalanches, debris flows and landslides as well as due to timber harvesting and beaver activity.
In small headwater streams, fallen trees are retained in places of their delivery to the channels, this resulting in a random pattern of wood deposition. In larger streams, wood is preferentially deposited in narrow channel sections and debris dams become the characteristic form of wood accumulation. In contrast, in mountain rivers wider than the height of trees growing on the banks, wood is preferentially deposited in wide channel sections where the transporting ability of flood flows is reduced.
Large woody debris exerts a significant influence on the morphology of mountain streams and rivers, on their potential for in-channel sediment storage and on the hydraulics of their flood flows. Wood also influences the functioning of aquatic ecosystems by increasing habitat diversity, providing habitat for many groups of invertebrates, fish and beavers, acting as a food source for many invertebrates and increasing the retention of organic matter in the channels. The beneficial impact of large woody debris on biotic and abiotic functions of fluvial systems should be taken into account in the management of mountain streams and rivers.
