Modelling individual tree diameter growth for Norway spruce in the Czech Republic using a generalized algebraic difference approach
base-age invariant approach Chapman-Richards function global parameters tree-specific parameters iterative nested regression National Forest Inventory
2017/6/26
Individual tree-based growth models precisely describe the growth of individual trees irrespective of stand complexity. These models are more useful than the stand-based growth models for effective ma...
Importance of the first thinning in young mixed Norway spruce and European beech stands
pre-commercial thinning diameter distribution h/d ratio skewness kurtosis
2018/3/6
Experimental results from the first thinning in mixed stands are not broadly experienced by forestry practice. To extend
the experience with the thinning of a mixed stand, we studied thinned and unth...
Changes in the nutrition and health status of young Norway spruce stands in the Krkonoše Mts. in a 17-year period
mountain forest height increment defoliation nutrients stress elements nutrient ratio
2018/3/6
For 17 Norway spruce stands located in the Krkonoše Mts. in the Czech Republic a long-term assessment of defoliation,
height increment, foliage concentration of nutrients (N, P, Ca, K, Mg) and s...
Multivariate analysis for assessment of the tree populations based on dendrometric data with an example of similarity among Norway spruce subpopulations
dendrometry hierarchical classification ordination Picea abies
2018/3/6
The new method for evaluation of tree populations presented here is based on a correlation analysis within a set of
dendrometric variables. The correlation analysis is carried out for each population...
Production and soil restoration effect of pioneer tree species in a region of allochthonous Norway spruce dieback
forest transformation regeneration methods birch aspen wood production soil chemistry
2017/4/6
The paper analyses the growth, structure, production and soil chemistry of different tree species stands 20 years after allochthonous spruce dieback. The experiment was carried out at lower altitudes ...
Below-canopy and topsoil temperatures in young Norway spruce and Carpathian birch stands compared to gaps in the mountains
air soil below-canopy climate microclimate stand environment
2016/11/11
Reduced air pollution load has allowed to use commercially oriented forestry in the Central European mountains since the 1990s. The goal is, however, to restore species- and age-diversified stable sta...
Effect of Bio-Algeen preparation on growth and mycorrhizal characteristics of Norway spruce seedlings
Ascophyllum nodosum ectomycorrhiza nurseries Picea abies seaweed
2016/7/6
In this paper, the effect of the Bio-Algeen® product (bio-alginate from the seaweed Ascophyllum nodosum (Linnaeus) Le Jolis) was evaluated in relation to basic mycorrhizal and growth characterist...
Fine root development and mycorrhization in Norway spruce stands one year after fertilization with potassium sulphate and wood ash
forest fertilization fine root ectomycorrhizal fungi
2016/1/29
We compared the effects of forest fertilization with wood ash and potassium (K) sulphate on growth and mycorrhizal colonization of fine roots and on other soil microorganisms in Norway spruce (Picea a...
COMPARISON OF DIFFERENT GROUND TECHNIQUES TO MAP LEAF AREA INDEX OF NORWAY SPRUCE FOREST CANOPY
LAI Sampling strategy PCA LAI-2000
2015/9/8
The leaf area index (LAI) of three monocultures of Norway spruce (Picea abies (L.) Karst), different in age and structure, was
measured by means of two indirect optical techniques of LAI field mappin...
Variability in leaf optical properties of Norway spruce crowns
Optical Properties Norway Spruce Crown Sampling
2015/8/20
Norway spruce (Picea abies /L./ Karst.) growing in montane and/or boreal environment is continuously exposed to the influence of
multiple environmental stress impacts. Stress factors increase nutriti...
