Estimation of within-gap regeneration height growth in managed temperate deciduous forests using bi-temporal airborne laser scanning data

Key message Multi-temporal airborne laser scanning (ALS) data were used to estimate regeneration stem height growth within gaps in uneven-aged deciduous forests. The height and height growth measured in the field were used to calibrate and validate

A review of the growth behaviour of stands and trees in even-aged, monospecific forest

Key message Metabolic, physiological and inter-tree competitive processes interact to determine long-term growth behaviour of stands and individual trees of even-aged, monospecific forests. Keywords Growth phases; Growth decline; Mortality; Self-thinning; Competition; Partitioning Publication West, P.W. A review

A growth-effective age-based periodic site-index for the estimation of dynamic forest site productivity under environmental changes

Key message A novel periodic site index is introduced for the quantification of dynamic forest site productivity. The measure is age-independent, sensitive to environmental changes and efficient for the estimation and prediction of stand height and stand

Band configurations and seasonality influence the predictions of common boreal tree species using UAS image data

Key message Data acquisition of remote sensing products is an essential component of modern forest inventories. The quality and properties of optical remote sensing data are further emphasised in tree species-specific inventories, where the discrimination of different

Potential processes leading to winter reddening of young Douglas-fir Pseudotsuga menziesii Mirb. Franco. in Europe

Key message Winter reddening of young Douglas-fir (Pseudotsuga menziesii Mirb. Franco), triggered by large thermal fluctuations in late winter, is a critical problem for European forestry. A literature review identified certain climatic conditions that are characteristic of

Do leaf lignin content or leaf mass-to-area bias the estimation of intrinsic water use efficiency from leaf bulk δ13C? A test with seedlings from five oak species

Key message Leaves of seedlings from five oak species (Quercus robur L.; Q. pubescens L.; Q. suber L.; Q. afares Pomel; Q. ilex L.) displayed large, mainly inter-specific, differences in leaf mass-to-area ratio (LMA) and lignin content,

Genetic structure of the European white elm (Ulmus laevis Pall., Ulmaceae) in Switzerland

Key message Populations of the European white elm (Ulmus laevis Pall.) in Switzerland can be considered natural. They show no evidence of genetic differentiation from other European populations. In the past, the U. laevis populations were probably

The rates of starch depletion and hydraulic failure both play a role in drought-induced seedling mortality

Key message The elapsed times to deplete starch concentrations and to reach a null hydraulic safety margin were related to tree seedling mortality under experimental drought. Starch concentration showed an accelerated decline across all species during the

Exploring the role of plant hydraulics in canopy fuel moisture content: insights from an experimental drought study on Pinus halepensis Mill. and Quercus ilex L.

Key message Understanding the impact of extreme drought on the canopy fuel moisture content (CFMC) is crucial to anticipate the effects of climate change on wildfires. Our study demonstrates that foliage mortality, caused by leaf embolism, can
