Comparison between the productivity of pure and mixed stands of Norway spruce and European beech along an ecological gradient
Hans Pretzsch,J. Block,Jochen Dieler,Phan Hoang Dong,Ulrich Kohnle,Jürgen Nagel,Hermann Spellmann,Andreas Zingg +7 more
TL;DR: In this paper, the authors used an empirically formed interaction model to investigate the mixing effect of Norway spruce and European beech on the growth and yield of mixed stands of Norway beech.
Productivity of mixed versus pure stands of oak (Quercus petraea (Matt.) Liebl. and Quercus robur L.) and European beech (Fagus sylvatica L.) along an ecological gradient
Hans Pretzsch,Kamil Bielak,J. Block,Arkadiusz Bruchwald,Jochen Dieler,Hans-Peter Ehrhart,Ulrich Kohnle,Jürgen Nagel,Hermann Spellmann,Michał Zasada,Andreas Zingg +10 more
TL;DR: It is found that on average, mixed stands of oak and beech exceeded biomass productivity in pure stands by 30 % or 1.7 t ha−1 year−1, as the growth of both species was benefitted by the mixture.

Complementarity in mixed-species stands of Abies alba and Picea abies varies with climate, site quality and stand density
TL;DR: In this paper, the authors examined how inter-and intra-specific interactions between Abies alba mill and Picea abies (L.) Karst varied with climate, site quality and stand density in the Black Forest of southwestern Germany, using spatially explicit neighbourhood indices.

How does silviculture affect storm damage in forests of south-western Germany? Results from empirical modeling based on long-term observations
TL;DR: In this paper, the influence of soil, site, forest stand, and tree parameters on storm damage, especially focusing on the influence on silvicultural interventions, was investigated using data from longterm growth and yield experiments in Baden-Wuerttemberg (southwestern Germany), which permit separation of storm damage from other causes of mortality for individual trees.

An inventory-based approach for modeling single- tree storm damage — experiences with the winter storm of 1999 in southwestern Germany
TL;DR: Based on individual tree damage data dating back to the gale "Lothar" (winter 1999) in Baden-Wurttemberg, Germany, a statistical model was developed to estimate the risk of storm damage for individ...
