Annual volume increment of the European forests—description and evaluation of the national methods used
By Erwin Dreyer On 13 June 2016 In Review paper
In order to obtain the necessary information for decision making etc., it is of increasing importance to be able to assess increment in a reliable way. Only repeated measurements on permanent sample plots in national forest inventories

Estimates of stem wood increments in forest resources: comparison of different approaches in forest inventory & consequences for international reporting
By Erwin Dreyer On 13 June 2016 In Review paper
Quality and reliability of forest resource assessments depend on the ability of national forest inventories (NFIs) to supply necessary and high-quality data. Over the last decades and especially since the 1990s, the NFIs in European countries have

Testing the applicability of BIOME-BGC to simulate beech gross primary production in Europe using a new continental weather dataset
By Erwin Dreyer On 12 June 2016 In Research paper
A daily 1-km Pan-European weather dataset can drive the BIOME-BGC model for the estimation of current and future beech gross primary production (GPP). Annual beech GPP is affected primarily by spring temperature and more irregularly by summer

How do consumers express their appreciation of wood surfaces? Norway spruce floors in Germany as an example
By Erwin Dreyer On 11 June 2016 In Research paper
A variety of visually different floor samples are presented online to consumers. Based on their individual verbal judgements of appreciation for visual surface characteristics, four distinct groups of floor surfaces were identified. This allows directing design and

Increased water use efficiency does not prevent growth decline of Pinus canariensis in a semi-arid treeline ecotone in Tenerife, Canary Islands (Spain)
By Erwin Dreyer On 8 June 2016 In Research paper
Intrinsic water use efficiency of Pinus canariensis (Sweet ex Spreng.) growing at a semi-arid treeline has increased during the past 37 years. Tree ring width by contrast has declined, likely caused by reduced stomatal conductance due to increasing

Integrated and systemic management of storm damage by the forest-based sector and public authorities
By Erwin Dreyer On 8 June 2016 In Review paper
Integrated and systemic management of wind damage risk can help to address decision-making requirements, mitigate economic impacts of storms, and improve collective well-being of the forest sector. In this context, public authorities should actively act to enable

Within-stem maps of wood density and water content for characterization of species: a case study on three hardwood and two softwood species
By Erwin Dreyer On 23 May 2016 In Research paper
Variability and interrelations between wood density, water content, and related properties were analyzed by CT scanning of five species. Relative water content of lumens is proposed as the best complement to basic specific gravity for discrimination of

Potassium fertilization of Spruce stands affects the distribution of fine roots but does not change ectomycorrhizal community structure.
By Erwin Dreyer On 23 May 2016 In Research paper
K fertilization of Spruce stands led to a significant increase in fine root biomass, fine root length, and root tip number in the mineral soil layer but does not affect the ecomycorrhizal community structure in the organic

Comparison of methods used in European National Forest Inventories for the estimation of volume increment: towards harmonisation
By Erwin Dreyer On 14 May 2016 In Review paper
The increment estimation methods of European NFIs were explored by means of 12 essential NFI features. The results indicate various differences among NFIs within the commonly acknowledged methodological frame. The perspectives for harmonisation at the European level

Low intra-tree variability in resistance to embolism in four Pinaceae species
By Erwin Dreyer On 8 May 2016 In Research paper
Variability of embolism resistance within individual trees was assessed in four Pinaceae species by using a single method of measurement: the Cavitron. Contrary to what has been previously observed, our findings show a small variability in embolism
