(2017) Distribution atlas of vascular plants in Albania. Hungarian Natural History Museum, Budapest). We identified the principal axes of variation of the flora and the bioclimatic variables that explain it. We also analysed the bioclimate of Albania by means of a self-organizing map (SOM) of the main climatic variables and the application of the global bioclimatic model of Rivas-Martínez. We compared the analysis based on the flora with that based on the bioclimate. The results divided Albania into eight floristic units corresponding to the main vegetation types (Carpinus orientalis woodlands, Quercus cerris woodlands, Quercus petraea and Fagus sylvatica woodlands, Quercus coccifera woodlands, Quercus coccifera and Quercus ithaburensis woodlands,...

Particular significance has been given edaphic and climatic factors at the base of the physiognomical, structural and floristic aspects of the different communities. The vegetation of littoral belt, salted lands and sandy plan hollow is determined by edaphic factor represented by the degree of salinity of water and only weakly by climate. The presence of the coniferous Mediterranean forest, of the Mediterranean shrubby vegetation and the absence of the broadleaf trees is to ascribe at a correlation between the climate and the water table level in the alluvial plain.

Markgraf in the 30ies, but still remains incomplete. This is a preliminary list of the plant communities resulting from the literature and from field research carried out during the last years and may represent a first contribution for further research. Many communities are described only by dominant species, other are quoted as nomina nuda. Some further syntaxa. probably present in the study area, are added.

The data are collected in more than 100 relevés during field trips, carried out in periods of intensive vegetation. It shows the presence of 11 endemic taxa, 23 nearendemics and more than 60 Balkan endemics. Two new species for science are described recently (Gymnospermium maloi Kit Tan & Shuka and Campanula aureliana Bogdanović, Rešetnik, Brullo & Shuka) and some others are confirmed about 100 years after (Sesleria albanica Ujhelyi and Stachys sericophylla Halacsy). Main threats, especially for the endemics and rare taxa of the southern region of Albania, are presented in this study, with recommendations for future steps. Some Natura2000 habitats are identified and a relevance of different habitat types like EUNIS, and Syntaxonomic classifications are linked together. The main aim of this study was the identification and presentati...

There are estimated not only some important general quantitative indicators of biodiversity, species and families richness, but qualitative as well, like biological and chorological forms and spectrum and presence of threatened species, based on the IUCN classification. This area is characterized, from our surveying, by a high level of the biodiversity. There are found 921 vascular plant species, distributed in 93 families, or 28.5% of the Albanian flora is found in only almost 1% of its surface. Biological and chorological spectrum analyze attests this region as an intermediary zone between Mediterranean and Sub-Mediterranean climate region. Dynamic viewpoint, flora of Dajti National Park is going toward degradation stages, because of fires, ov...

It has a surface of 27,371 hectares and apart from high floristic richness, plant and habitat types, has also different historical, cultural and religious aspects. This Park represents the third highest altitude (2415,7 m recognised as “Cuka Partizan”) of the Central and South Albania. It is located in the Northeast part of the Southern region of the country (Figure 1) and is characterized by diverse geological formations such as organogenic limestone deposits, flysch, alluvial deposits, gravel, sand and clay, flishoidale combinations, sandy‐clayey‐calcareous etc. (Qiriazi 2001).

Dajti National Park (DNP) is one of the most interesting protected areas, Second Category of IUCN, located on the central part of Albania. The vegetation of DNP, especially thermophilous broadleaves forests represent different degradation stages because unsustainable practices, fires, overgrazing and traditional use in the past. Basic part of the study is the ecology and life history of Quercus tree species in the landscape of DNP, which is related to abiotic site factors and human land use. This includes recording of abiotic site factors by field methods, the identification of the vegetation and land use systems of the area plots. A comprehensive analysis on plant communities has been necessary. Combined floristic, ecological site data and human factors, inform us about the landscape history and present situation. Classification of vegetation types defining species groups and plant communities, through principals of Zurich–Montpellier school, have been done. Potential veg...
