Utilization of browse supply and moose Aices alces Linnaeus, 1758 browsing intensity in relation to tree height (0.5-3.0 m) were estimated for Scots pine in thickets and willow in willow-birch shrubs. The thickets examined provided different browse resources (0.5, 2.0 and 3.2 t dry wt/ha) and the highest utilization (about 50%) was found in the poorest one (thicket 1). In the willow-birch shrubs the use of browse was high and amounted to 85% of total production in both the winter periods studied. The number and increase of biomass of browsed twigs per stem (or plot} was generally associated with the increase of tree height. Browsing intensity depended on the tree height. Pines of 1.5-1.99 m height were characterized by the greatest browse utilization (76.3%). Moose removed significantly more biomass and twigs from pines growing in the central zone of the thicket 1 than from those growing in the marginal zone. However, in the wiilow-birch shrubs the utilization of all tree height classes was above 70% of the production and moose browsed not only the last year's growth of shoots but also that of earlier years.
