Owing to the national boundaries the flora list of a spacious geographical area is not unified and as well has mistakes.
The same holds true in respect of the Carpathian-Pannon region, in which our countries wholly or partly belong. We would like to suggest that we should compile the dendroflora list (tree, shrub, sub-shrub, dwarf shrub species) of this area uniformly according to the major geographical units.
To our conception each participant should compile the dendroflora list according to their countries’ geographical units. After gathering these lists we would unify them collectively.
