    Abrupt height growth setbacks show overbrowsing of tree saplings, which can be reduced by raising deer harvest

    Intensive ungulate browsing significantly impacts forests worldwide. However, it is usually not single browsing events that lead to sapling mortality, but the little-researched interactions of browsed saplings...

    Analyzing effects of intra- and interspecific competition on timber quality attributes of Fagus sylvatica L.—from quality assessments on standing trees to sawn boards

    Timber quality is the main driver of timber prices and is strongly influenced by the competition a tree experiences until its day of harvest. Regulating competition is an integral part of silviculture, and the...
