That provides supplementary data on the radial growth of trees, which we collect as part of the 5-year inventories on intensive monitoring plots. We track the annual dynamics of radial growth using two types of girth bands – plastic ones from a German manufacturer and stainless-steel ones from a Czech manufacturer. The purpose of monitoring radial growth with girth bands is to determine the impacts of environmental and climatic factors on tree growth between the two 5-year inventories. That gives us significantly better data on tree growth conditions than the 5-year inventories, where extreme events are averaged out. Additionally, in 2022, we installed electronic dendrometers with high-frequency monitoring of radial growth changes on all plots within the intensive monitoring network in Slovenia. The goal is to determine the impacts of environmental and, especially, climatic factors on the intra-seasonal dynamics of radial growth. That is crucial for understanding the effects of negative climatic factors on the radial growth of treesV okviru intenzivnega monitoringa gozdnih ekosistemov že od leta 2009 s pomočjo ročnih dendrometrov spremljamo de- belinsko priraščanje dreves na letnem nivoju. Gre za dopolnilni podatek o debelinskem priraščanju dreves, ki ga pridobimo v okviru petletnih inventur na ploskvah intenzivnega monitoringa. Letno dinamiko debelinskega priraščanja spremljamo z dvema tipoma ročnih dendrometrov : plastičnimi, nemškega proizvajalca, in nerjavnimi, češkega proizvajalca. S spremljanjem debelinske rasti z ročnimi dendrometri želimo ugotoviti vpliv okoljskih in podnebnih dejavnikov na rast dreves med dvema petletnima inventurama. Tako dobimo bistveno boljše podatke o stanju priraščanja dreves kot s petletnimi inventurami, kjer ekstremni dogodki izginejo v povprečju. V letu 2022 smo dodatno na vse ploskve namestili tudi elektronske dendrometre z visoko frekvenco spremljanja spreminjanja debelinskega prirastka na ploskvah intenzivnega monitoringa v Sloveniji. Z njimi želimo ugotoviti vplive okoljskih in podnebnih dejavnikov na znotraj sezonsko dinamiko debelinskega priraščanja. To je ključno za razumevanje vpliva negativnih podnebnih dejavnikov na debelinsko priraščanje drevesTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaZveza gozdarskih društev Slovenije
