Waldartenlisten der Farn- und Blütenpflanzen, Moose und Flechten ...

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