Raziskali smo edini znani domnevno avtohtoni nahajalisci cemprina (Pinus cembra L.) v Sloveniji: pod Krnesom in pri Beli peci, obe v pogorju Smrekovca. Z napravo GPS smo dolocili lokacije osebkov cemprina, jih premerili, dolocili razdaljo do najbližjega sosednjega cemprina, ocenili zdravstveno stanje, z metodo izvrtkov dolocili starost dveh osebkov in zabeležili znake pomlajevanja. Nahajalisci cemprinov v pogorju Smrekovca smo prikazali na geoloski in pedoloski karti, lokacije posameznih cemprinov pa na ortofoto posnetkih. Pod Krnesom smo zabeležili 12 cemprinov, pri Beli peci 4. Cemprini pri Beli peci so v povprecju visji in debelejsi, verjetno tudi starejsi. Starost dveh vzorcenih cemprinov pod Krnesom ocenjujemo na 76 in 91 let. Povprecni debelinski prirastek pri vzorcenem cemprinu na gozdnem robu je 1,97 mm/leto, pri osebku v sestoju pa 1,25 mm/leto. Pod Krnesom smo nasli osebek mladja in na dveh osebkih opazili storže. Lahko gre za marginalno populacijo cemprina na njegovem robnem rastiscu na skrajnem vzhodnem obmocju Alp v Sloveniji. Najpomembnejsi argument proti samoniklosti je razporeditev 9 osebkov pod Krnesom ob deželni meji in frati. Zapisov o saditvi ni. Cemprini v pogorju Smrekovca naj tudi v prihodnje obdržijo status dendroloske naravne vrednote. Kljucne besede: cemprin, Pinus cembra L., avtohtonost, ohranjevanje genskega sklada, redka vrsta, marginalna populacija, Smrekovec, Slovenija, Alpe This research studied the only two sites where the Swiss stone pine (Pinus cembra L.) is considered to be native to Slovenia: one below Mount Krnes and one near Mount Bela Pec, both of which form part of the Smrekovec massif. The exact locations of individual trees were determined using a GPS device. The trees were measured and inspected in terms of health, and distances were calculated between the closest neighbouring trees. In addition, the age of two individuals was determined by increment boring and there were signs of rejuvenation. The two sites in the Smrekovec massif are indicated on bedrock and soil maps while the locations of individual Swiss stone pines are presented on ortophoto images. A total of 12 Swiss stone pines were found to grow below Mount Krnes and another 4 near Mount Bela Pec. The latter group of stone pines have greater mean diameters and heights and are probably older than the Krnes group of stone pines. The estimated ages of two trees from below Mount Krnes are 76 and 91 years. The individual growing on the edge of the forest has a mean annual increment of 1.97 mm, while the other one growing inside the forest has a mean annual increment of 1.25 mm. A Swiss stone pine seedling was found below Mount Krnes and cones could be observed on two individuals. The two sites are potentially home to marginal populations of the Swiss stone pine on the edge of its natural range in the easternmost part of the Alps in Slovenia. The most prominent argument against nativity is the distribution of the 9 individuals below Mount Krnes – it follows a regional border and the edge of a grassland. No planting records exist. The Swiss stone pines of the Smrekovec massif must retain their status as a dendrological site of natural interest.
