What is your discount rate? Experimental evidence of foresters’ risk and time preferences
By AFS On 24 January 2018 In All published articles, Research paper, Special issue/Topical collection
Topical collection: Risk Analysis The elicited time preference rate of German foresters is around 4.1%. Foresters working for private enterprises are more risk-averse and have a lower time preference than other foresters. This group difference should be

Modeling sapling distribution over time using a functional predictor in a generalized additive model
The effect of adult trees on sapling density distribution during the regeneration fellings is determined in a Pinus sylvestris L. Mediterranean forest using generalized additive models. Context. Spatial pattern of adult trees determines the number of new

Efficiency of using spatial analysis for Norway spruce progeny tests in Sweden
Spatial analysis could improve the accuracy of genetic analyses, as well as increasing the accuracy of predicting breeding values and genetic gain for Norway spruce trials. Context. Spatial analysis has been increasingly used in genetic evaluation of

Density reduction in loblolly pine (Pinus taeda L.) stands to increase tree C assimilation: an approach with the dual δ13C and δ18O isotope signatures in needles
In the context of increasing droughts related to climate change, our results showed that heavy thinning and/or very low initial planting density can increase CO2 assimilation rate in needles, and may be used as a short-term management

Modeling thinning effects on fire behavior with STANDFIRE
By AFS On 12 January 2018 In All published articles, Research paper, Special issue/Topical collection
Topical collection: Mensuration and modelling for forestry in a changing environment We describe a modeling system that enables detailed, 3D fire simulations in forest fuels. Using data from three sites, we analyze thinning fuel treatments on fire

European Forest Types: toward an automated classification
By AFS On 12 January 2018 In All published articles, Research paper, Special issue/Topical collection
Topical collection: ICP Forests The outcome of the present study leads to the application of a spatially explicit rule-based expert system (RBES) algorithm aimed at automatically classifying forest areas according to the European Forest Types (EFT) system

Evaluation of the cumulative effect of drip irrigation and fertigation on productivity in a poplar plantation
Combined drip irrigation and fertigation significantly increased stem volume and biomass production in a poplar plantation, and showed a cumulative effect over years. The promoting effects were mainly attributable to increased nitrogen and water availability in the

Mature exotic conifer stands have greater catches of the EU-protected Geomalacus maculosus than adjacent peatland or clear-felled stands—implications for forestry
Mature exotic Sitka spruce (Picea sitchensis; Bong. Carrière)-dominated stands, particularly trees of greater circumference, result in greater numbers of Geomalacus maculosus (Allman) captures than adjacent clear-felled stands and adjacent peatland with Before-After-Control-Impact-Paired analysis indicating lower catches of

Responses of the structure and function of the understory plant communities to precipitation reduction across forest ecosystems in Germany
Understory plant communities are essential for the recruitment of trees making up future forests. Independent of plant diversity, the understory across different forest ecosystems shows considerable physiological acclimation and structural stability towards drought events, which are expected

Photosynthesis and growth responses of Fraxinus mandshurica Rupr. seedlings to a gradient of simulated nitrogen deposition
During an N-deposition simulation experiment, we showed that low to medium addition of N had beneficial effects on growth and photosynthetic rates of Fraxinus mandshurica Rupr. seedlings, while beyond a threshold of 80 kg N ha−1 year−1,
