2015/3/16
The paper analyses possibilities of repeated use of Norway spruce (Picea abies [L.] Karst.) in the regeneration of existing Norway spruce stands, in the regeneration of large-area clearcuts, and in th...
Different technologies of floodplain forest regeneration from the aspect of soil changes
floodplain forest regeneration soil changes soil organic matter
2015/3/16
Like in other types of forests the greatest changes in the soil of floodplain forest stands occur during their regeneration. These changes are manifested as changes in the content and dynamics of orga...

This paper presents the results of investigations on natural forest regeneration in Norway spruce (Picea abies L. Karst.) monocultures in the Ukrainian Beskids with the use of FORKOME model prognostic...
Light distribution within forest edges in relation to forest regeneration
advanced planting forest edge light compensation point photon flux density
2015/2/6
Light conditions were measured along six transects from 35 m inside of a mixed Norway spruce/Scots pine forest to an adjoining clear-cut in NW-Austria. Photosynthetic photon flux density (PFD) was rec...
