For the second edition of the list of vascular forest plants, suggestions that had been made since 2003<br />
were subjected to discussion. The formerly uniform group of trees (B), which had also comprised lianas<br />
and epiphytes was differentiated according to their association with forests in the same manner as shrubs<br />
and herbaceous plants.<br />
While presence in vegetation plot data and Ellenberg indicator values for light had allowed a preliminary<br />
classification of vascular plants, this method was only partly applicable for bryophytes and lichens,<br />
because cryptogams have often not been consistently included in the sampling of forest un<strong>der</strong>storey, and<br />
because there are only negligible plot data for epiphytic and rock-dwelling species. This entails a stronger<br />
weight of expert judgements in these groups.<br />
Preliminary data were submitted to experts for review. Experts submitted comments and suggestions<br />
concerning methodology and group definitions as well as re-classification of taxa. Incoming expert<br />
judgements were compiled and adapted into the revised lists. In the case of bryophytes and lichens<br />
workshops delivered final decisions. Problems remaining after the workshops were solved by individual<br />
searches (literature, querying of experts).<br />
All native taxa, archaeophytes and neophytes present in the current standard lists for Germany were<br />
consi<strong>der</strong>ed. Association with forest was usually judged at species level. Where useful and feasible,<br />
subspecies, varieties etc. were consi<strong>der</strong>ed. Where the association was doubtful, the classification was<br />
done at the respective higher taxonomic level, which may result in classifications at the level of species<br />
groups or aggregates.<br />
Beyond association with forests and substrates (cryptogams), supplementary information on Ellenberg<br />
indicator values (light, temperature, continentality, moisture, soil reaction and nutrients) was extracted<br />
from the GermanSL 1.2 reference list.<br />
