Earth system models must predict forest responses to global change in order to simulate future global climate, hydrology, and ecosystem dynamics. These models are increasingly adopting vegetation demo...
The prosperity of various forest regeneration methods was evaluated on the prepared windthrow area established in 2010 in a previously allochthonous coniferous stand growing in mid-elevations of the...
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...
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 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...
