The vegetation of Buna River Protected Landscape is described. The area comprises both the alluvial plain of the lower course of the Buna river that marks the boundary between Montenegro and Albania, ...and a carbonatic range. The vegetation is characterized by a high β-diversity (27 alliances and 46 associations), especially in wetlands and dry grasslands. In the area it is possible to distinguish 1 dunal and 4 hygro-sequences in the alluvial plain and 3 xeroseries in the carbonatic range. Associations Clematido viticellae-Punicetum granati and Periploco graecae-Alnetum glutinosae are described as new.
V članku je opisana vegetacija v zavarovanega območja ob reki Buna. Območje obsega aluvialno ravnino ob spodnjem teku reke Buna, ki predstavlja mejo med Črno goro in Albanijo in karbonatnim hribovjem. Za vegetacijo je značilna visoka β diverziteta (27 zvez in 46 asociacij), še posebej pa mokrišča in suha travišča. V območju smo izločili 1 sekvenco na sipinah, 4 higro sekvence na aluvialni ravnici in 3 ksero serije na karbonatnem masivu. Asociaciji Clematido viticellae-Punicetum granati in Periploco graecae-Alnetum glutinosae sta novo opisani.
A phytosociological survey was carried out in a poorly known travertine area of southern Tuscany harbouring a rich vegetation mosaic with chamaephytic garrigues, species-rich xerophytic grasslands, ...chasmophytic coenoses, annual species-dominated communities, shrublands and thermophilous deciduous forests. Field sampling and data analysis allowed to identify and characterize several community types, some of which of significant interest due to their ecological specificity and rarity in peninsular Italy. In particular, our data confirm the associations Pistacio terebinthi-Paliuretum spinosae and Pistacio terebinthi-Quercetum pubescentis, respectively a shrub and forest community type previously unknown for Tuscany. In addition, a new therophytic association of travertine debris named Sedetum hispanico-caespitosi and placed in the Hypochoerion achyrophori alliance (Brachypodietalia distachyi order, Tuberarietea class) is also described. Finally, dynamic relationships between the vegetation types are highlighted and the presence of conservation priority habitats in the area are pointed out.
Opravili smo fitocenološko raziskavo na malo znanem območju na travertinu v južni Toskani z bogatim mozaikom vegetacije z hamefitskimi garigami, vrstno bogatimi kserofitskimi travniki, hazmofitskimi združbami, združbami prevladujočih enoletnic, grmišči in termofilnimi listantimi gozdovi. S terenskim vzorčenjem in analizo podatkov smo opisali in označili številne vegetacijske tipe. Nekateri so še posebej pomembni, ker so ekološko posebni in redki na italijanskem poltotoku. Potrdili smo prisotnost asociacij Pistacio terebinthi-Paliuretum spinosae in Pistacio terebinthi-Quercetum pubescentis, grmiščnih in gozdnih združb, ki sta bili do sedaj neznani v Toskani. Opisali smo novo terofitsko asociacijo na travertinskem grušču Sedetum hispanico-caespitosi in jo uvrstili v zvezo Hypochoerion achyrophori (red Brachypodietalia distachyi, razred Tuberarietea). Prikazali smo dinamične odnose med vegetacijskimi tipi in izpostavili naravovarstveno prednostne habitate na raziskovanem območju.
