Abstract
Fitocenološko in floristično so preučeni logi ob reki Dravi med Mariborom in Središčem ob Dravi (subpanonsko fitogeografsko območje). Po standardni srednjeevropski fitocenološki metodi je bilo narejenih 33 fitocenoloških popisov, ki so uvrščeni v šest asociacij: Salicetum albae, Carici elongatae-Alnetum glutinosae, Alnetum glutinosae s. lat., Stellario nemorum-Alnetum glutinosae, Fraxino-Populetum in Lonicero caprifolii-Quercetumroboris. Slednji je opisana nova subasociacija: -caricetosum albae. Primerjava poglavitnih ekoloških in rastiščnih dejavnikov na podlagi Landoltovih fitoindikacijskih vrednosti je pokazala, da sta vlažnost rastišča in vsebnost hranil v tleh glavna ekološka dejavnika, ki vplivata na razvoj posameznega tipa logov. Vegetacijska dinamika, sukcesivno nadomeščanje združb oziroma conacija ugotovljenih tipov poteka od belovrbovja (Salicetum albae) preko sintaksonov Fraxino-Populetum in Lonicero caprifolii-Quercetum roboris caricetosum albae v dobovo belogabrovje (Lonicerocaprifolii-Quercetum roboris). Znotraj opisanega niza pa v posebnih rastiščnih razmerah uspevajo različne fitocenoze črne jelše. Ugotovljeno je, da so proučevani logi slabo ohranjeni in izpostavljeni močnim antropogenim vplivom. Veliko grožnjo tem gozdnim fitocenozam predstavljajo tudi tujerodne invazivne rastline. Opravljena je fitocenološka in floristična primerjava z logi ob Muri, ki nakazuje na nekatere razlike med združbami bele vrbe in črne jelše obeh rek.

Title:Phytosociological analysis of floodplain forests along the Drava river in sub-panonian phytogeographical region of Slovenia
Abstract:
A phytosociological and floristic analysis of floodplain forests along the Drava river between Maribor and Središče ob Dravi (NE Slovenia, sub-Pannonian phytogeographical region) is given. Applying the standard Central-European phytosociological method 33 relevés were made, which are classified in six associations: Salicetum albae, Carici elongatae-Alnetum glutinosae, Alnetum glutinosae s. lat., Stellario nemorum-Alnetum glutinosae, Fraxino-Populetum and Lonicero caprifolii-Quercetum roboris. In the latter a new subassociation -caricetosum albae is described. Comparison of ecological factors on the basis of Landolt indicator values has showed, that humidity of the site and nutrients are the main factors affecting the development of a vegetation type. The succession or zonation of the vegetation types goes from white willowstands (Salicetum albae) through the stands of syntaxa Fraxino-Populetumand Lonicero caprifolii-Quercetum roboris caricetosum albae to European hornbeam and pedunculate oak forests (Lonicero caprifolii-Quercetum roboris). Inbetween described successional series different phytocoenoses of black alder are found on specific growing sites. It was found, that investigated forests are poorly preserved and exposed to intense anthropogenic influences. In addition non native invasive plants also represent a big threat to this forests communities. A phytosociological and floristic comparison with floodplain forests along Mura river was made, which indicates some differences between the stands of white willow and black alder of the two rivers.
