Seven spruce species on a mountain site - performance, foliar nutrients, and forest floor properties in stands 20 years old

open access: yesiForest - Biogeosciences and Forestry, 2019
Norway spruce is often considered to have a negative impact on a site, yet it is native to many mountain regions of Europe. The relative influence of Norway spruce on site properties has frequently been compared with that of both broadleaved and other ...

Dissolved organic carbon and nitrogen leaching from Scots pine, Norway spruce and silver birch stands in southern Sweden [PDF]

open access: yes, 2011
The effects of three common tree species – Scots pine, Norway spruce and silver birch – on leaching of dissolved organic carbon and dissolved nitrogen were studied in an experimental forest with podzolised soils in southern Sweden. We analyzed soil water

Nutrient dynamic of Norway spruce (Picea abies (L) Karst) litter mixed with litter of Beech (Fagus orientalis lipsky), Alder (Alnus subcordata C.A.Meyer) and Maple (Acer velutinum Boiss.) in pure Norway spruce plantation of Lajim site [PDF]

open access: yesتحقیقات جنگل و صنوبر ایران, 2012
Plant litter decomposition plays an important role in forest soil fertility due to nutrient cycling and soil organic matter formation. Litter decomposition, results in return of leaves nutrient to soil and supply of necessary elements for plant growth ...

Effects of phenotypic selection on height-diameter ratio of Norway spruce and Scots pine in Sweden

open access: yesSilva Fennica, 2018
Genetically improved Norway spruce ( (L.) Karst.) and Scots pine ( L.) are extensively used in operational Swedish forestry plantations. However, relatively little is known about the stem slenderness (height-diameter ratio) of genetically improved ...

Climate-growth relationships at different stem heights in silver fir and Norway spruce [PDF]

open access: yes, 2012
We investigated the effect of climate on variations in annual ring-area increment along the stem of dominant silver fir (Abies alba Mill.) and Norway spruce (Picea abies (L.) Karst.) trees in the Black Forest, southwestern Germany, to test the hypothesis

Growth-climate responses of Picea sitchensis [Bong.] Carr. versus Picea abies [L.] Karst. in the British Isles and Central europe

open access: yesCentral European Forestry Journal, 2023
Introduced tree species have become increasingly important in the context of the ongoing climate change. This paper focuses on the dendrochronology of the most widespread introduced tree species in the British Isles – Sitka spruce (Picea sitchensis [Bong.

Drought sensitivity of Norway spruce is higher than that of silver fir along an altitudinal gradient in southwestern Germany [PDF]

open access: yes, 2013
For Central Europe, climate projections foresee an increase in temperature combined with decreasing summer precipitation, resulting in drier conditions during the growing season.
