Abstract

In a 4.5 km long, predominantly forest-covered section of the Suhorica valley between the localities Bibec and Bižaj (central Brkini Hills, southwestern Slovenia, quadrant 0350/4), the area of a proposed reservoir for additional water supply for Slovenian Istria (which has been suspended for the time being!) we identified eight plant communities. The most important in terms of nature conservation are riparian forests of black alder (Lamio orvalae-Alnetum glutinosae) as well as riverine and semi-dry slope meadows (Anthoxantho-Brometum erecti caricetosum pallescentis, Danthonio-Scorzoneretum villosae holcetosum lanati). We recorded approximately 450 taxa of vascular plants in the valley and its slopes, including 20 protected and 20 Red List species. The most threatened are Gladiolus illyricus and Orchis coriophora.

 

Izvleček

Na okoli 4,5 km dolgem, v glavnem gozdnatem odseku doline Suhorice med krajema Bibec in Bižaj (osrednji Brkini, jugozahodna Slovenija, kvadrant 0350/4), kjer so pred nekaj leti načrtovali gradnjo velikega zajetja za dodatno oskrbo Slovenske Istre z vodo (namero so za zdaj opustili!), smo ugotovili osem rastlinskih združb, med katerimi so naravovarstveno najbolj pomembni logi črne jelše (Lamio orvalae-Alnetum glutinosae) in obrečni in pobočni polsuhi travniki (Anthoxantho-Brometum erecti caricetosum pallescentis, Danthonio-Scorzoneretum villosae holcetosum lanati). V dolini in na pobočjih nad njo smo popisali okoli 450 taksonov praprotnic in semenk, med njimi jih je 20 zavarovanih in prav toliko tudi na rdečem seznamu. Najbolj ogroženi sta vrsti Gladiolus illyricus in Orchis coriophora.
