Abstract. In birch forests of bilberry type in vegetation conditions the influence of
age statement of leaf-canopy on biometrical parameters of spruce undergrowth under
the Syamzhenskiy district of the Vologda region is studied. It is established that with the
birch age increase the conditions for growth and development of conifer undergrowth
deteriorate, as a result it changes the biomass structure, morphometrical parameters
and age of under canopy needles.
Keywords: birch stands of various ages, blueberry types of growing places’
conditions, spruce undergrowth, biomass structure.
