Both spatially explicit and spatially non-explicit individual tree crown width models were
developed for Norway spruce (Picea abies (L.) Karst.) and European beech (Fagus sylvatica …

Key message Crown width–diameter relationship, which is significantly influenced by
various characteristics, was modelled using tree and stand measures, and plot-level random …

Key message Height–diameter models were developed specifically for Pinus nigra Arn., an
important commercially species extending in the Mediterranean and central Europe region …

Tree height to crown base (HCB) is an important variable commonly included as one of the
predictors in growth and yield models that are the decision-support tools in forest …

Tree height measurements are laborious and require more time and effort compared to tree
diameter measurements. That being the case, height-diameter (HD) models are usually …

Key message The proposed height–diameter model applicable to many tree species in the
multi-layered and mixed stands across Czech Republic shows a high accuracy in the height …

Alternative methods have been used for developing tree basic and generalized height–
diameter models, including non-linear least-squares regression, non-linear mixed-effects …

Various forest models that estimate volume, site index, growth and yield, biomass, and
sequestrated carbon amounts are based on the information of the tree heights. The tree …

The height and diameter of trees are important variables in estimating the aboveground
biomass of trees. Tree height measurements are often difficult in tropical forests hence tree …

Crown width is a tree variable that is commonly used as an important predictor in forest
growth and yield models that serve as decision-support tools in forestry. Here, we developed …
