Tree potential growth varies more than competition among spontaneously established forest stands of pedunculate oak (Quercus robur)

Key message Analyses of dendrochronological data from 15 recently established tablished stands of pedunculate oak (Quercus robur L.) revealed that functions describing potential tree growth in the absence of neighbours varied more between stands than functions describing

Harmonising, improving and using social and recreational data in National Forest Inventories across Europe

Key message National Forest Inventories (NFIs) hold promise for monitoring and valuing of non-productive forest functions, including social and recreational services. European countries use a range of methods to collect social and recreational information within their NFI

Short-term effects of biochar on soil CO2 efflux in boreal Scots pine forests

Key message During the first summer, wood biochar amendments increased soil temperature, pH, and soil CO 2 effluxes in a xeric boreal Scots pine forest. The increase of soil CO 2 efflux could be largely explained by

Effect of different conditions of storage on seed viability and seedling growth of six European wild fruit woody plants

Key message Malus sylvestris (L.) Mill., Pyrus communis (L.), Sorbus aucuparia (L.), Prunus avium (L.), Prunus padus (L.), and Cornus sanguinea (L.) are related, co-occurring species producing orthodox seeds. However, we observed differences in their response to

Using forest gap models and experimental data to explore long-term effects of tree diversity on the productivity of mixed planted forests

Key message In this exploratory study, we show how combining the strength of tree diversity experiment with the long-term perspective offered by forest gap models allows testing the mixture yielding behavior across a full rotation period. Our

Predicting rut depth induced by an 8-wheeled forwarder in fine-grained boreal forest soils

Abstract Key message Rut depth in fine-grained boreal soils induced by an 8-wheeled forwarder is best predicted with soil moisture content, cumulative mass of machine passes, bulk density and thickness of the humus layer. Context Forest machines

Growth parameters and resistance to Sphaerulina musiva-induced canker are more important than wood density for increasing genetic gain from selection of Populus spp. hybrids for northern climates

Abstract Key message New genotypes of hybrid poplars from the Aigeiros and Tacamahaca sections have great potential for increasing genetic gain from selection. The most promising traits are associated with productivity and resistance to Sphaerulina musiva -induced

Towards a more robust approach for the restoration of mangroves in Vietnam

Abstract Key message Globally, mangrove forests are under threat from a range of causes. They also represent a large potential form of climate mitigation and adaptation via reforestation, and this investment may contribute to restoration efforts and

The effects of truncating the angle count sampling method on the Austrian National Forest Inventory

Abstract Key message Truncating the angle count sampling plots leads to a higher stock estimate because fewer trees are missed. It also causes a higher uncertainty of the estimates. Context The Austrian National Forest Inventory changed its

Advantage of clonal deployment in Norway spruce (Picea abies (L.) H. Karst)

Abstract Key message There is considerable genetic gain of tree volume from clonal deployment in Norway spruce (Picea abies (L.) H. Karst) and clonal deployment will have at least 50% more or double genetic gain than the
