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

Biotic and abiotic disturbances modify tree structure and degrade stand health. Accurate
geospatial data on stand structure is important for monitoring tree growth, forest health …

Crown size estimations are of vital importance in forest management practice. This paper
presents nonlinear models that were developed for crown width prediction of Black pine …

Height-to-diameter at breast height (DBH) ratio (HDR) is an important tree and stand stability
measure. Several factors such as stand dynamics, natural and anthropogenic disturbances …

Tree crown measures, such as crown ratio (CR) can be used as one of the important
predictor variables in forest growth and yield models. CR is influenced by the tree and …

The inclusion of quadratic mean diameter (QMD) and relative spacing index (RSI)
substantially improved the predictive capacity of height–diameter at breast height (dbh) and …

Height to crown base (HCB) of a tree is an important variable often included as a predictor in
various forest models that serve as the fundamental tools for decision-making in forestry. We …

Individual tree growth and yield models precisely describe tree growth irrespective of stand
complexity and are capable of simulating various silvicultural alternatives in the stands with …

In recent Eucalyptus cold-tolerance trials, E. benthamii has shown good growth rates as well
as cold tolerance for USDA Plant Hardiness Zones 8 and 9. This study developed growth …

Tree crowns are commonly measured to understand tree growth and stand dynamics.
Crown ratio (CR—crown depth-to-total height ratio) is significantly affected by a number of …
