Raziskovanje potenciala rasti jelke (Abies alba) na nekarbonatni podlagi v različnih ekoloških razmerah v luči podnebnih sprememb

Orel, Manca (author), Levanič, Tomislav (mentor)

V diplomski nalogi smo raziskovali potencial rasti jelke (Abies alba Mill.) na nekarbonatni podlagi v luči podnebnih sprememb. Glavni cilj naloge je bil raziskati, kako se jelka driva na povprečne mesečne temperature in padavine v rastni sezoni. Raziskava je zajemala obdobje od 1920 do danes. Temeljila je na dendrokronološki analizi. Vzorce izvrtkov smo odvzeli na treh lokacijah različnih nadmorskih višin: Grmače (356 m), Gornji Grad (530 – 600 m) in Pohorje (858 m). Merjenje širine branik smo opravili v sistemu ATRICS, statistično obdelavo pa v programu R Studio. Rezultati so pokazali, da se jelka na vseh treh lokacijah podobno odziva na klimatske dejavnike, a so bile razlike v primernosti posameznih rastišč očitne. Jelka je imela najslabše rastne pogoje na Grmačah, kjer so visoke povprečne temperature in primanjkljaj zadostne količine padavin izrazito negativno vplivali na rast. Rastišče na območju Gornjega Gradu je imelo sicer boljše rastne pogoje za jelko, vendar močna korelacija med poletnimi temperaturami priraščanjem jelk predstavlja tveganje za prihodnost. Ugotovili smo, da ima rastišče na Pohorju najboljše rastne pogoje za jelko. Potrebno je poudariti, da so vplivi podnebnih sprememb v zadnjem desetletju zaznani na vseh treh lokacijah, zato je za bolj natančno napovedovanje potenciala vrste priporočljivo nadaljnje spremljanje priraščanja.

• Title: Exploring the growth potential of european silver fit (Abies Alba) on non-carbonate soils under different climatic conditions and altitudes in the context of climate change

Abstract

In the thesis, we studied growth potential of silver fir (Abies alba Mill.) on non-carbonate substrates in regard to climate change. The main goal was to research how silver fir responds to average monthly temperatures and precipitation during the growing season. Work was based on dendrochronological analysis. Research timeframe covered data from 1920 to the present. We collected samples of three locations on different altitudes: Grmače (356 m), Gornji Grad (530 – 600 m) and Pohorje (858 m). We measured the width of the tree rings using the ATRICS system, and we statistically processed the data in R studio. Least appropriate growing conditions for silver fir were noticed in Grmače, due to high average temperatures and a shortage of sufficient rainfall. Growing conditions for silver fir in Gornji Grad has shown better potential, but the strong correlation between summer temperatures and silver fir growth indicates a risk for the future. We found the best growing conditions for silver fir in Pohorje. It is important to emphasize that the impacts of climate change have been noticeable at all three locations over the past decade. Therefore, for more accurate predictions of the species’ future potential, continued monitoring of growth patterns is recommended.
