(1990): Spontaneous vegetation in mountain villages of Northern Greece. -- Folia Geobot. Phytotax., Praha, 25: 27--61. -- The synanthropie vegetation in seven villages of Northern Greece (N Pindhos and Olympus massif) -- situated either in the Quercion con]ertae or in the /~ageta//a zone -- is analyzed on the basis of about 100 phytoseciologieal relev6s. The most important vascular plant species of ruderal sites have also been mapped floristically. Nineteen plant communities are discernible, some of which are mentioned for the first time here. Nevertheless, the author refrains from hastily describing new associations, unless a more detailed phytosoeiological data basis on ruderal vegetation in the Southern Balkans is available. A table refers to differences and similarities between the recognized plant communities in Gr~k villages and those which correspond to them in Central Europe. Non-industrial methods of agri- culture and animal husbandry are among the most important conditions for the remarkable rich vegetation in Greek mountain villages. EINF(~HRUNG, ZIELSETZUNG 0bwohl keine Pflanzengesellsehaft strong und ausschliesslich an DSrfer gebunden ist, so haben doch mehrere ihren Schwerpunkt in liindlichen Siedlungen; dies gilt ebenso fiir manehe Arten. Es ist folglich statthaft, von dSrflicher Vegetation, yon Dorfflora zu sprechen. Gemeint sind Kombinationen synanthroper Pflanzenar- ten und -gesellschaften, die unter den Bedingungen dSrflicher Arbeits- und Lebens- weisen und ihrer Einwirkung auf den Standort entstanden sind.
