Dst: Green wood density data for a few tree species

In treecm: Centre of Mass Assessment and Consolidation of Trees

Description

Wood density is used to convert wood volume measures in the field to their fresh weights. It is measured in \frac{kg}{m^3}.

Format

A data frame with 170 observations on the following 3 variables. data.frame: 170 obs. of 3 variables: $ species: chr "Abies alba" "Abies alba" "Abies balsama" "Abies grandis" ... $ group : Factor w/ 2 levels "conifer","dicot": 1 1 1 1 1 1 1 1 1 1 ... $ density: int 545 577 529 449 465 673 689 497 673 577 ...

Details

Density is measured at humidity level 50 wood humidity. The dataset is provided as a reference only, please be cautioned about using these values on your samples.
