The influence of Picea abies on herb vegetation in forest plant communities of the Veporské vrchy Mts.

Journal of Forest Science, 2010
Natural mixed beech-fir forests were quite widely replaced by spruce dominated stands in Slovakia. Given the demands on the assessment of the forest status as well as on stopping the biodiversity loss it is required to evaluate the influence of Picea ...

How close to nature is close-to-nature pine silviculture?

Journal of Forest Science, 2016
Structural parameters of Scots pine stands (129-191 years) on their natural sites (270-600 m a.s.l.) are described on 6 permanent research plots (PRP; 3 in managed stands using near-natural silvicultural practices and 3 in stands without active forest ...

Comparison of Soil Microbial Communities Across Three Natural Forest Stands Differing in Canopy Composition and Stand Age in the Greater Khingan Mountains, Northeast China

Diversity
Cold-temperate forest ecosystems in northeastern China have experienced significant changes due to long-term anthropogenic disturbances. To elucidate how different natural forest stands influence the structure, function, and assembly processes of soil ...

Genetic analysis of Latvian Salix alba L. and hybrid populations using nuclear and chloroplast DNA markers

iForest - Biogeosciences and Forestry, 2017
Latvia is at the northern border of the species range of S. alba L. in Europe, and there has been some debate whether the Latvian populations of S. alba are autochthonous, as this species has long been planted in Latvia as an ornamental tree in gardens ...

Spatially explicit structure of natural stands dominated by black spruce

Silva Fennica, 2013
Black spruce [ (Mill.) BSP] regeneration emerges in clusters near the pre-existing boles within a few years after the passage of fire. This paper tested the hypothesis that black spruce forests still maintain the spatial structure deriving from postfire ...
