Abstract

Prispevek obravnava prve rezultate sledenja učinkov troposferskega ozona na gozdni vegetaciji v povezavi z aktivnostmi intenzivnega monitoringa gozdov (IM) in na ploskvah za umerjanje v okviru programa ICP Forest Konvencije CLTRAP v Sloveniji. Na desetih ploskvah IM potekajo meritve s pasivnimi vzorčevalniki koncentracije troposferskega ozona, hkrati se na izbranem gozdnem robu v bližini merilnega mesta opravljajo opazovanja značilnih ozonskih poškodb listja gozdnega drevja in grmovja. Prvi izsledki kažejo, da so izmerjene koncentracije troposferskega ozona večje v zahodnem delu države (Fondek na Trnovski planoti, Ankaran) in na višjih nadmorskih višinah (Lontovž pod Kumom, Borovec pri Kočevski Reki, Slavnik). Poškodbe vegetacije niso zmeraj večje zaradi višjih koncentracij ozona zaradi vpliva podnebnih dejavnikov in vodnega režima rastlin. Kljub temu pa so bile opažene tipične poškodbe listja zaradi prisotnosti ozona na večini opazovanih drevesnih in grmovnih vrstah. Zaradi uporabe pasivnih vzorčevalnikov neposrednih vzročnih povezav med poškodbami listja in koncentracijami nismo mogli potrditi ozona.

Secondary title:	Ozone damages on forest vegetation of Slovenia
Secondary abstract:	The article deals with the first results of monitoring of tropospheric ozone damage, observed as foliage damage on the selected forest tree and shrub species in Slovenia at the plots of ICP-Forest Level II. Foliage damage was accompanied by ozone concentration measurement, carried out by passive samplers. The first results of the monitoring showed that higher ozone concentrations were measured in the west and south-west part of the country, especially at higher elevations. Foliage damage does not always correlate withthe ozone concentration due to the interference of climate factors and water regime of plants. However, typical visible damage was found in needles and leaves of almost all observed tree and shrub species. Due to the method of monitoring we have not been able to correlate measured ozone concentrations and visible injuries in plant leaves.
