GEOMORPHOLOGICAL CHARACTERISTICS OF THE MASSIF PRENJ, 2008, Lepirica Alen
The researched area of the mountain massif Prenj with surface of 463 km2 is located in the zone of high karst of Outer Dinarides of Bosnia and Herzegovina. It is circular mountain morphostructure with assymetrical transversal profile. Developed in Mesozoic subhorizontal layers of limestone and dolomite over 3500 thick, fissured by numerous reverse and normal faults. Prenj is folded-thrusted mountain massif (2103 m a.s.l.) uplifted during neotectonic phase of Dinarides development, structurally represented by three blocks. A high degree of correlation between lithology, fault structures and relief has been determinated. The main fault structures caused by rotation of Prenj blocks which were reflected on different orientations of stretching of the mountain ridges and composite valleys of Neretva, Konjika Bijela, Mostarska Bijela, Glogonica and Id-bar. Thrusts express tectonic, lithological, and morphological border of the considered mountain with inter mountain Neogene depressions in the North and South. Netectonic movements and dominanting carbonate composition of the terrain have influenced on reticular relief structure of the massif. Linear landforms of ridges formed in karst are neotectonically, rectilinearly and half-arc elongated up to 12 km. In regards to morphogenesis during the Quaternary, the massif is characterized by development: derasional, glacial, periglacial, karstic, fluviokarstic, fluviodenudational and fluvial erosional and accumulational processes and landforms. Finally, geomorphological regionalization of Prenj was made on the basis of the criteria of similarity of morpho-evolutionary, structural-lithological and orographical characteristics.

Vascular plant biodiversity richness and endemo relictness of the karst mountains Prenj-Čvrsnica-Čabulja in Bosnia and Herzegovina (W. Balkan) , 2011, Redhić, Sulejman, Barudanović, Senka, Trakić, Sabina, Kulijer Dejan
The complex of karstic mountains Prenj-Čvrsnica and Čabulja in Herzegovina (w. Balkan) is characterized by high level of both geomorphology and biodiversity richness. This has been confirmed by a research of plant communities, their structure and dynamics, which took place throughout several seasons from 2005 to 2008. In the investigated area the vegetation cover, as a reliable indicator for specific karstic circumstances, is being differentiated in a great number of syntaxa (plant communities) that encompass over 2,500 vascular plants. On the surface of about 100,000 ha identified were up to 236 plant associations, 116 alliances and 63 vegetation orders that belong to 34 classes. This amounts 34% of total of vegetation classes at the European level and 100% of so far known vegetation classes in Bosnia and Herzegovina, over 80% of classes at the level of Montenegro and Croatia.There have been identified nearly 450 endemic and relict species, which is why most of the identified communities are endemic and relict ones, not only at the level of association but also at the level of higher syntaxonomic categories, such as alliance and order. The highest diversity level characterizes those communities that make a direct contact with the calcareous geological foundation either in rock crevices or screes on limestone. That high level of floristic and vegetation richness places this area among the most diverse areas both in Europe and whole Mediterranean.That high level of floristic and vegetation richness places this area among the most diverse areas both in Europe and whole Mediterranean. Such pattern of vegetation (syntaxonomy) and floristic diversity confirms the unique role of dinaric-herzegovina karst as a complex of unrepeatable ecological factors on global scale.
