13. Tree rings, wood density and climate–growth relationships of four Douglas-fir provenances in sub-Mediterranean SloveniaLuka Krajnc, Jožica Gričar, Jernej Jevšenak, Polona Hafner, Robert Brus, 2022, original scientific article Abstract: Tree rings, wood density and the climate–growth relationship of four Douglas-fir provenances were analysed separately for the juvenile and adult phases. Four provenances were selected from an existing IUFRO provenance trial planted in 1971 based on their diameter at breast height and vitality. Increment cores were extracted from individual trees, on which we measured tree-ring widths (RW), earlywood widths (EWW) and latewood widths (LWW). Wood density was assessed in standing trees using resistance drilling. The climate–growth correlations were calculated between provenance chronologies of RW, EWW, LWW and latewood share, and the day-wise aggregated Standardised Precipitation-Evapotranspiration Index (SPEI). The analysis was done separately for the juvenile and mature phases of growth. Provenances 1064 (Jefferson) and 1080 (Yelm) exhibited larger annual radial increments than provenances 1028 (Merrit) and 1089 (Cathlamet). The two provenances with the highest annual radial increment in the juvenile phase did not exhibit the same trend in the adult phase. In all provenances, RW, and consequently EWW and LWW, were wider in the juvenile than in adult phase. The share of latewood was in all cases higher in juvenile wood than in mature wood. All four provenances had similar wood densities in both analyzed growth phases. Our analysis showed that when selecting the most promising provenance for planting, possible changes in relative growth rate from the juvenile to adult phase need to be considered.

14. Zakonodaja in pravni okviri gojenja tujerodnih drevesnih vrst v gozdovih SlovenijePia Caroline Adamič, Robert Brus, Kristjan Jarni, 2022, review article Abstract: Namen raziskave je bil pregled zakonodaje in pravnih okvirjev gojenja tujerodnih drevesnih vrst v slovenskih gozdovih. Na ravni Evropske unije je za uvedbo, uporabo in gospodarjenje s tujerodnimi drevesi pomembnih več pravnih instrumentov, npr. Direktiva Sveta o trženju gozdnega reprodukcijskega materiala, Habitatna direktiva, Uredba o preprečevanju in obvladovanju vnosa in širjenja invazivnih tujerodnih vrst. V slovenski zakonodaji področje njihovega vnosa in potencialnega vpliva ureja predvsem Zakon o ohranjanju narave, pomembni pa so še Uredba o posebnih varstvenih območjih (območjih Natura 2000), Zakon o gozdovih, Zakon o gozdnem reprodukcijskem materialu, Pravilnik o določitvi provenienčnih območij, Uredba o zavarovanih prosto živečih rastlinskih vrstah. Iz pravnih aktov izhaja, da za opravljanje gozdarske dejavnosti gojenje tujerodnih dreves v Sloveniji ni prepovedano, doselitev tujerodnih vrst je načeloma dovoljena, za vnos novih tujerodnih vrst pa je potreben ustrezen postopek, ki vključuje presojo vplivov na okolje, odobri pa ga pristojni minister. Slovenska zakonodaja tako ponuja možnosti za gojenje določenih tujerodnih drevesnih vrst, ki bi lahko bile zaradi boljše odpornosti proti biotskim in abiotskim dejavnikom ključne pri prilagajanju gozdov na podnebne spremembe, hkrati pa so zaradi hitre rasti in kakovostnega lesa gospodarsko zanimive.
