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...
Musts with an increased content of lignans from added spruce knot chips
enrichment of must HMR CONI antioxidant activity determined by FRAP total polyphenol concentration sensory evaluation
2016/12/9
Red and white musts were enriched with the lignan hydroxymatairesinol, which is the main lignan contained in spruce knots. Chips from the milled spruce knots were then used to enrich grape musts. Afte...
USING AIRBORNE SMALL-FOOTPRINT LASER SCANNER TO ASSESS THE QUANTITY OF SEEDLINGS IN AN UNEVEN-AGED SPRUCE FOREST
Regeneration uneven-aged forest laser scanner data canopy structure
2015/11/10
The relationships between measures of forest structure as derived from airborne laser scanner data and the variation in quantity of young trees established by natural regeneration in a size-diverse sp...
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...
SIMULATING CANOPY GAP FRACTION OF COMPLEX 3D FOREST SCENES OF PICEA SITCHENSIS (SITKA SPRUCE)
Forestry 3D canopy modelling gap fraction
2015/9/8
We present an application of 3D canopy modelling for assessing the structural accuracy of complex 3D structural models of
Sitka spruce. Such models can be used to simulate canopy reflectance at the l...
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...
Utilization of spruce (Picea abies [L.] Karst.) and beech (Fagus sylvatica L.) wood in plywood production using different processing pressures
composite compression veneer density profile
2015/5/5
In this research the spruce plywood board and combined spruce-beech plywood board were prepared
in laboratory conditions using two levels of processing pressure
Stand-replacing disturbance does not directly alter the succession of Norway spruce regeneration on dead wood
decaying logs natural regeneration Picea abies
2015/5/5
Density of regeneration in European subalpine Norway spruce (Picea abies) forests is typically low with
regeneration primarily located on dead or decaying wood. The post-disturbance development of t...
Evaluating the Influence of Disturbance and Climate on Red Spruce (Picea rubens Sarg.) Community Dynamics at its Southern Range Margin
dendrochronology climate change tree-rings
2014/11/26
Picea rubens(red spruce) populations experienced a synchronous rangewide decline in growth and vigor starting in the 1960’s, which was likely caused by climate change or environmental disturbances (e....
Model Estimates of Nutrient Uptake by Red Spruce Respond to Soil Temperature
Mechanistic Modeling Imax Root Growth Rate Soil Buffer Power
2013/3/12
A better understanding of the mechanisms that control nutrient acquisition in the context of plant and ecosystem responses to climate change is needed. Mechanistic nutrient uptake models provide a mea...
RED DEER (Cervus elaphus) BARK STRIPPING ON SPRUCE WITH REGARD TO SPATIAL DISTRIBUTION OF SUPPLEMENTAL FEEDING PLACES
Cervus elaphus red deer bark stripping Norway spruce Picea abies forest damages
2009/11/27
Forest damages caused by red deer and some other large herbivore species occasionally feeding on tree bark, are a grave ecological and economic problem in many parts of the world. Winter supplemental ...
NATURAL REGENERATION ECOLOGY OF A SECONDARY ALTIMONTANE SPRUCE FORESTS AT JELENDOL
altimontane spruce forest natural regeneration ecological factors irradiation gap
2009/11/27
Natural regeneration of altimontane spruce forests at Jelendol is retarded due to many factors. In autumn 2003, gaps of different size and parts of the surrounding stand were covered with a 5 x 5 grid...
THE INFLUENCE OF CLIMATE ON TREE-RING MAXIMUM LATEWOOD DENSITY IN NORWAY SPRUCE (Picea abies (L.) Karst.) AT TWO SITES IN SLOVENIA
