Selected plant functional traits of all species in data set "sveg"

Description

For each species in "sveg" a selction of 23 traits are taken from the "Flora Indicativa by" Landolt et al. (2010). These are all nominal variables. Score 1 indicates the trait is present, score 0 it is absent. Hence, there is no such things like missing values.

Usage

s

Life strategy "stress-tolerant" (adapted to harsh environmental conditions), range 1-3

Details

Species traits from vascular plants and brypphytes stem from different lists in Landolt et al. (2010). Note that this data set was not in cluded in the original dave package, but added in version 1.5 only.
