Ecology and management of northern red oak (Quercus rubra L. syn. Q. borealis F. Michx.) in Europe: A review

Northern red oak (Quercus rubra L. syn. Q. borealis F. Michx.) was introduced to Europe in 1691 and currently covers over 350, 000 ha, being found all over out continent, except the coldest part of Scandinavia. It is a fast growing and valuable broadleaved tree due to its ecological characteristics, good wood properties and high economic value. Northern red oak prefers deep, loose, moderately humid and acid soils, without compact horizons and of at least moderate fertility. It is either naturally regenerated by seed using a group shelterwood system or planted using seedlings of European provenance, collected in certified seed stands. As northern red oak is light-demanding, its management should be dynamic and includes heavy interventions (clening- respacing and thinning from above), in order to provide enough crown space for the final crop trees. These trees should produce large diameter trees for valuable end-uses (e.g., veneer, solid vurniture, lumber, etc.) within a rotation period generally of 80 to 100 years. The necessity for pruning (both formative and high) depends on the stand stocking at establishemnt, the subsequent silvicultural interventions as well as the occurrence of forking.
