Improved models of harvest-induced bark damageAnnals of Forest Science - Tập 73 - Trang 233-246 - 2015
Aikaterini Nakou, Udo Hans Sauter, Ulrich Kohnle
We provided a precise quantitative analysis of the factors at the origin of bark damage during harvesting operations and developed a model able to predict them accurately. The major factors were the distance of trees to skid trails, the intensity of removals, the harvesting system as well as the interactions between the distance of trees to skid trails with harvesting systems, t...... hiện toàn bộ
Radial growth changes following hemlock woolly adelgid infestation of eastern hemlockAnnals of Forest Science - Tập 71 - Trang 595-602 - 2014
David M. Walker, Carolyn A. Copenheaver, Audrey Zink-Sharp
Hemlock woolly adelgid (Adelges tsugae) is an invasive insect that is defoliating and killing eastern hemlock (Tsuga canadensis) in the USA. We quantified changes in tree-ring growth rates and wood anatomy for living trees infested with hemlock woolly adelgid across six sites from Massachusetts (42°41′N) to Georgia (34°53′N) to identify growth responses of eastern hemlock that had survived infesta...... hiện toàn bộ
Quantifying the risk mitigation efficiency of changing silvicultural systems under storm risk throughout historyAnnals of Forest Science - Tập 76 - Trang 1-16 - 2019
Fabian Müller, Andrey Lessa Derci Augustynczik, Marc Hanewinkel
Silvicultural adaptations throughout history resulted in an increasing mitigation efficiency towards storm risk, quantifiable through an increasing conditional value at risk and decreasing average damage loss. Recently recommended silvicultural systems for spruce stands in Central Europe, like the group selection system, showed the highest mitigation efficiency towards storm, co...... hiện toàn bộ
Effects of rotation length on the grade recovery and wood properties of Sitka spruce structural timber grown in Great BritainAnnals of Forest Science - Tập 69 - Trang 353-362 - 2011
John R. Moore, Andrew J. Lyon, Stefan Lehneke
Rotation length is known to affect timber quality in many plantation species, but its effect on the properties of Sitka spruce (Picea sitchensis) structural timber has not been quantified. Te purpose of this study was to compare selected wood properties and grade recovery of Sitka spruce structural timber cut from different radial positions within a log reflecting different cambial ages. Structura...... hiện toàn bộ
Post-fire resprouting ability of 15 non-dominant shrub and tree species in Mediterranean areas of NE SpainAnnals of Forest Science - Tập 64 - Trang 883-890 - 2007
Lidia Quevedo, Anselm Rodrigo, Josep Maria Espelta
Post-fire resprouting ability of the non-dominant tree and shrub species of the Mediterranean Basin has not yet been experimentally tested, although this group contributes to maintain the richness of Mediterranean plant communities. In this study, we have analyzed the post-fire recovery ability of 15 woody species that occur in relatively low abundance in dry and sub humid Mediterranean areas in N...... hiện toàn bộ
