Forest managers need site productivity estimates for tree species growing in mixed stands. Models developed in the past are generally for pure stands and don’t factor in the effects of climate change ...
Thinning experiment in the spruce and beech mixed stands on the locality naturally dominated by beech ?growth, litter-fall and humus
thinning spruce beech

The paper is a contribution to research on thinnings in mixed (spruce-fir-beech) stands situated in the fifth forest altitudinal zone in the central part of Slovakia. Three plots were tended by free c...
The elasticity of growth in pure and mixed stands of Norway spruce (Picea abies [L.] Karst.) and common beech (Fagus sylvatica L.)
elasticity of growth density-growth-relationship risk spreading
2015/1/28
This study indicates that the growth of mixed stands with Norway spruce (Picea abies [L.] Karst.) and common beech (Fagus sylvatica L.) is more stable across a range of stand densities than it is in p...

Following Kyoto protocol considerable research efforts have been made on carbon sequestration assessment of forest stands. The aim of the present study was to test the adequacy of two documented metho...
Comparison of Decomposition Rates of Beech(Fagus orientalis Lipsky)and Spruce(Picea orientalis(L.)Link)Litter in Pure and Mixed Stands of Both Species in Artvin, Turkey
Decomposition litter quality beech spruce pure and mixed stands
2009/1/12
The decomposition of spruce, beech and mixed litters of spruce and beech was investigated over 3.5 years in beech, spruce and mixed (beech/spruce) stands using less than 1.5 mm mesh litter bags. Initi...
