Select a set of traits to measure. How many and which traits to measure will be determined by ecological and practical factors. Ecologically speaking, the traits used depend on the disturbances of interest and expert knowledge of how the traits directly determine or are related to those disturbances. Practically speaking, most trait lists are limited by what can be found in the literature or easily measured in the field or on herbarium specimens. Using too many traits will make it difficult to find discrete groups of plants (Skarpe, 1996), but using too few will leave open the question of whether a critical trait was left out.
