achieved this via so-called "functional traits" of species – wood density, specific leaf area (SLA, area per unit dry mass of leaf) and maximum height. Trees differ in these traits in a consistent way [...] international team of researchers has revealed that three functional traits – wood density, specific leaf area and maximum height – affect competition in predictable ways across all forested biomes worldwide.

Three different methods and 2 different versions of parameters of [...] site properties. Nonlinear mixed-effects models with covariates were fitted to individual-tree basal area increment (BAI) data from the Swiss National Forest Inventory. Data from 1983-2006 were used for model [...] properties. In general, BAI was positively related to DBH, and negatively related to slope, basal area of larger trees, stand density (not so for the shade tolerant beech), mean DBH of the 100 thickest

In these five sub-plots [...] statistical forest inventory procedures are labour intensive, while the actual coverage of evaluated plot area is limited. Many forest parameters rely on assessments based on expert knowledge. These expert assessments [...] such as canopy cover and canopy gaps, vertical density of the canopy layer within the forest edge area, and stem density.
