Modelling soil nitrogen mineralisation in semi-mature pine stands of South Africa to identify nutritional limitations and to predict potential responses to fertilisation

Abstract Key Message Estimates of available nitrogen (based on topsoil nitrogen mineralisation rates) in semi-mature stands of Pinus radiata (D Don.) as well as pure species and hybrids of Pinus elliottii (Engelm.) in South Africa display a

Rethinking global carbon storage potential of trees. A comment on Bastin et al. (2019)

Abstract Key Message Bastin et al. 2019 use two flawed assumptions: 1) that the area suitable for restoration does not contain any carbon currently, and 2) that soil organic carbon (SOC) from increased canopy cover will accumulate

Effects of diameter distribution errors on stand management decisions according to a simulated individual tree detection

Abstract Key Message Tree-level forest inventory data are becoming increasingly available, which motivates the use of these data for decision-making. However, airborne inventories carried out tree-by-tree typically include systematic errors, which can propagate to objective function variables

Effects of plot length and soil texture on runoff and sediment yield occurring on machine-trafficked soils in a mixed deciduous forest

Abstract Key message Runoff decreased significantly in each soil texture group, as plot length increased (2–40 m), whereas sediment yield showed an increasing trend. Runoff and sediment yield were higher in the clayey soil than in the

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

Mechanical properties of “flexure wood”: compressive stresses in living trees improve the mechanical resilience of wood and its resistance to damage

Abstract Key message Mechanical acclimation of young poplars ( Populus tremula × Populus alba , INRA 717-1B4) submitted to periodic stem bending is mainly driven by compressive strains. Flexure wood and compressive flexure wood exhibit higher mechanical

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

Can mixed pine forests conserve understory richness by improving the establishment of understory species typical of native oak forests?

Abstract Key message A positive effect of mixed pine forests (Pinus sylvestris L. and Pinus pinaster Ait.) on the understory richness and tree regeneration was observed with respect to monospecific stands. Understory species typical of the native

Trade-offs between economic profitability, erosion risk mitigation and biodiversity in the management of uneven-aged Abies alba Mill. stands

Abstract Key message Multi-objective forest planning methods were used to assess the trade-offs between three ecosystem services: timber production, erosion protection and biodiversity. The use of trade-off analysis helps to define proper weights for the management objectives
