20.500.12556/DiRROS-29753 Lesna zaloga drevesnih in grmovnih vrst glede na višinske pasove v Sloveniji primerjalna analiza in razvojne značilnosti Growing stock of tree and shrub species across elevation zones in Slovenia comparative analysis and developmental characteristics slovenski gozdovi spadajo med vrstno pestrejše, saj v njih raste kar 71 avtohtonih drevesnih vrst. navkljub veliki vrstni pestrosti slovenskih gozdov v lesni zalogi le teh s 60 % prevla-dujeta bukev (Fagus sylvatica) in navadna smreka (Picea abies). Lesna zaloga merskih dreves narašča z nadmorsko viši-no, tako ima zgornji višinski pas največjo lesno zalogo, in sicer 398 m3/ha. obratno od lesne zaloge merskih dreves in grmov se shannon-wienerjev indeks vrstne pestrosti z nadmorsko višino zmanjšuje. podobno je tudi pri shannon-wienerjevem indeksu vrstne pestrosti podmerskih dreves, s tem da je v ni-žinskem pasu nekoliko manjši. delež smreke v lesni zalogi merskih dreves se veča z nadmorsko višino. v nižinskem pasu (do 300 m) znaša 10,2 %, v najvišjem pa 49,4 %. bukev je v zadnjem obdobju postala najpogostejša drevesna vrsta v dele-žu lesne zaloge merskih in podmerskih drevesnih vrst, kar nakazuje tudi na prihodnje večanje lesne zaloge deleža mer-skih dreves bukve. v nižinskem in spodnjem višinskem pasu (nižjem od 700 m) je delež lesne zaloge podmerskih dreves: termofilnih listavcev – predvsem malega jesena (Fraxinus ornus), črnega gabra (Ostrya carpinifolia), tujerodne robinije (Robinia pseudoaccacia) in sencozdržnega belega gabra (Car-pinus betulus) precej večji od deleža lesne zaloge teh drevesnih vrst v lesni zalogi merskih dreves. v merski zalogi podmer-skih grmovnih vrst tako v celotni sloveniji kot tudi v vseh vi-šinskih pasovih prevladuje navadna leska (Corylus avellana), ta prav tako močno prevladuje v vseh višinskih pasovih – naj-večji delež ima v višinskem pasu od 700 do 1.000 m (91,3 %), najmanjšega pa v nižinskem pasu (61,9 %). Slovenian forests are among the most species-rich in Europe, with 71 native tree species recorded. Despite this high diversity, two species—European beech (Fagus sylvatica) and Norway spruce (Picea abies)—dominate the growing stock, together accounting for 60% of the total volume. The growing stock of trees and shrubs above the 10 cm DBH (diameter at breast height) threshold increases with elevation, with the highest elevation zone reaching 398 m³/ha. In contrast, the Shannon–Wiener diversity index for trees and shrubs above 10 cm DBH decreases as elevation increases. A similar pattern is observed for the Shannon–Wiener index of small trees and shrubs (below the 10 cm DBH threshold), although values in the lowest elevation zone are slightly lower. The proportion of Norway spruce in the growing stock of trees above 10 cm DBH increases markedly with elevation, rising from 10.2% in the lowest elevation zone (<300 m) to 49.4% in the highest zone. In recent years, European beech has become the dominant species in the growing stock of both trees and shrubs above 10 cm DBH, as well as small trees and shrubs below 10 cm DBH, indicating a likely further increase in the proportion of beech in future growing stock development. In elevation zones below 700 m, the growing stock of small trees and shrubs contains a substantially higher proportion of thermophilous broadleaved species—particularly manna ash (Fraxinus ornus), hop hornbeam (Ostrya carpinifolia), the non-native black locust (Robinia pseudoacacia), and shade-tolerant hornbeam (Carpinus betulus)—compared to their proportion in the growing stock of trees and shrubs above 10 cm DBH. In the growing stock of small shrubs across Slovenia and within all elevation zones, common hazel (Corylus avellana) predominates. Its growing stock proportion is highest in the 700–1000 m elevation zone (91.3%) and lowest in the lowest elevation zone (61.9%). nacionalna gozdna inventura Slovenija gozdovi višinski pasovi raznolikost drevesne vrste grmovne vrste lesna zaloga national forest inventory Slovenia forests elevation zones diversity tree speciesshrub species growing stock true false false Slovenski jezik Angleški jezik Znanstveno delo 2026-06-04 13:22:37 2026-06-04 13:22:37 2026-06-05 04:05:58 0000-00-00 00:00:00 2026 0 0 Nasl. z nasl. zaslona; Opis vira z dne 4. 6. 2026; str. 5-20 iss. 1 Vol. 67 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*52 2335-2914 10.3986/fbg0118 280491523 https://ojs.sazu.si/folia_bio_geo/article/view/8091 1 b23dc4c7-6007-11f1-9215-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=44718 RAZ_Pintar_Anze_Martin_2026.pdf RAZ_Pintar_Anze_Martin_2026.pdf 1 E20FC1174E831C9E869CA63B88697843 20f4f796b2abc097f85fe0962f3518fa8258be0c82ea18e9ad182dec3d15798b c724b536-6007-11f1-9215-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=44719 Gozdarski inštitut Slovenije 0 0 0
