High nutrient supply and interspecific belowground competition enhance the relative performance of Picea mariana (Mill). B.S.P seedlings over Picea glauca [Moench] Voss. under elevated CO2

Key message We tested how nutrient supply and interspecific belowground competition affect ecophysiological and morphological responses to elevated CO2 in black ( Picea mariana (Mill). B.S.P) and white spruce ( Picea glauca [Moench] Voss.). It is found

Multi-actor perspectives on afforestation and reforestation strategies in Central Europe under climate change

Key message Understanding forest genetic diversity and national legislation on trade and utilization of forest reproductive material (FRM) are key aspects for management and adapting forests to climate change. Despite concerns about the negative effects of climate

Can epiphytic lichens of remnant Atlantic oakwood trees in a planted ancient woodland site survive early stages of woodland restoration?

Key message Epiphytic lichens of remnant Atlantic oakwood trees, enclosed within a recently planted conifer matrix, show ability to survive early stages of woodland restoration (conifer removal). Abstract Context Atlantic oakwood, ancient semi-natural woodland (ASNW), supports important

Assessing the land expectation value of even-aged vs coppice-with-standards stand management and long-term effects of whole-tree harvesting on forest productivity and profitability

Key message Whole-tree harvesting makes forests more profitable than conventional harvest as long as the impact on tree growth remains under 2.3% for even-aged oak ( Quercus petraea (Matt.) Liebl.) and 3.4% for sweet chestnut ( Castanea

Potential of machine learning and WorldView-2 images for recognizing endangered and invasive species in the Atlantic Rainforest

Key message We found high accuracy classification (Fmeasure = 95%, on cross-validation) of Araucaria angustifolia (Bertol.) Kuntze, an endangered native species, and Hovenia dulcis Thunb. an aggressive, invasive alien species in WorldView-2 multispectral images. In applying machine

Oviposition preference of the forest cockchafer (Melolontha hippocastani Fabr. 1801) at the stand scale depends on oak proportion, canopy openness and ground accessibility

Key message Melolontha hippocastani is a major pest in European mixed and broadleaf forests. Investigating its oviposition behavior, we observed that a dense shrub layer reduces the density of egg clusters and eggs in the soil. Conversely,

Variation of cork porosity along the stem in harvested cork oak (Quercus suber L.) trees

Key message Cork porosity, due to lenticular channels, varied along the stem of Quercus suber L. Lenticular channels’ area, rather than their number, decreased upwards along the stem. Area decrease was observed regardless of tree size and

Estimating the willingness to pay for regulating and cultural ecosystem services from forested Siwalik landscapes: perspectives of disaggregated users

Key message We assessed forest users’ willingness to pay (WTP) for regulating and cultural forest services based on their socio-economic status (rich vs. poor), proximity to forests (nearby vs. distant), and forest management modalities (community forestry vs.

SurEau: a mechanistic model of plant water relations under extreme drought

Key message A new process-based model, SurEau , is described. It predicts the risk of xylem hydraulic failure under drought. Abstract Context The increase in drought intensity due to climate change will accentuate the risk of tree

Genetic gains in wood property can be achieved by indirect selection and nondestructive measurements in full-sib families of Japanese cedar (Cryptomeria japonica. D. Don) plus tree clones

Key message We assessed the narrow-sense heredity and genetic gains of multiple traits obtained using the indirect selection method for progeny of Cryptomeria japonica D. Don by artificial crossing. Using stress wave velocity and Pilodyn penetration depth
