Abstract:V Sloveniji spremljamo stanje in razvoj gozdov na nacionalni ravni z Nacionalno gozdno inventuro (NGI). V prispevku smo analizirali pestrost pojavljanja drevesnih in grmovnih vrst ter preverili pojavljanje tujerodnih drevesnih vrst v slovenskih gozdovih. Glede na literaturo v Sloveniji uspeva 71 avtohtonih drevesnih vrst, od katerih jih je bilo 60 zaznanih med merskimi drevesi na mreži ploskev NGI gostote 2 x 2 km. Največje povprečno število merskih dreves in grmov, kot tudi Shannon-Wienerjev indeks vrstne pestrosti, smo ugotovili na vzorčnih ploskvah v Predalpski ekološki regiji (H' = 0,85), najmanjše pa v Alpski ekološki regiji (H' = 0,58). Lesna zaloga merskih dreves in grmov v celotni Sloveniji dosega 330,7 m3/ha ± 2,1 %, lesna zaloga podmerskih dreves in grmov (prsni premer do 10 cm) pa 9,7 m3/ha ± 5,9 %. V lesni zalogi merskih drevesnih in grmovnih vrst prevladujeta bukev (Fagus sylvatica) (31,9 %) in smreka (Picea abies) (28,2 %), med merskimi grmovnimi vrstami je največ navadne leske (Corylus avellana) (85,0 %). Na ploskvah NGI je bilo zabeleženih 10 različnih tujerodnih drevesnih vrst na 138 ploskvah, največkrat so bile popisane v Submediteranski in Predpanonski ekološki regiji. V lesni zalogi tujerodnih drevesnih vrst prevladuje robinija (Robinia pseudoacacia). V lesni zalogi podmerskega drevja z 32,4 % prevladuje bukev, več kot 10,0 % lesne zaloge prispevata še navadna smreka in mali jesen (Fraxinus ornus). V lesni zalogi popisanih podmerskih grmovnih vrst prevladuje leska z 78,3 %, več kot 2 % dosegajo še rumeni dren (Cornus mas), navadni srobot (Clematis vitalba) in črni bezeg (Sambucus nigra). Predstavljeni rezultati kažejo, da je kombinacija panelnega sistema, večjega števila vzorčnih ploskev (3027) in izboljšanega šifranta omogočila prvo celostno objektivno ovrednotenje pestrosti pojavljanja drevesnih in grmovnih vrst ter prisotnosti tujerodnih vrst v slovenskih gozdovih.

Title:Diversity and occurrence of native and non-native tree and shrub species in national forest inventory plots in Slovenia
Abstract:In Slovenia, the National Forest Inventory (NFI) is used to monitor the state and development of forests at the national level. In this paper, we analysed the diversity of tree and shrub species and assessed the presence of non-native tree species in Slovenian forests. According to the literature, Slovenia hosts 71 autochthonous tree species, of which 60 were found among the trees measured on the 2 x 2 km NFI density plot grid. The highest average number of trees and shrubs, as well as the Shannon-Wiener index of species diversity, were observed in sample plots located in the Pre-Alpine Ecological Region (H’ = 0.85), while the lowest values were found in the Alpine Ecological Region (H’ = 0.58). The total growing stock of trees and shrubs in Slovenia is 330.7 m3/ha ± 2.1%, with the growing stock of small trees and shrubs (less than 10 cm DBH for trees and shrubs) estimated at 9.7 m3/ha ± 5.9%. Common beech (Fagus sylvatica) (31.9%) and Norway spruce (Picea abies) (28.2%) dominate the growing stock of tree and shrub species, while common hazel (Corylus avellana) (85.0%) represents the highest proportion of shrub species. Ten different non-native tree species were identified across 138 NFI plots, with the highest distributions in the Sub-Mediterranean and Pre-Pannonian Ecological Regions. Black locust (Robinia pseudoacacia) dominates the growing stock of non-native tree species. Among small trees (those with a DBH of less than 10 cm), common beech represents 32.4%, with Norway spruce and manna ash (Fraxinus ornus) each contributing more than 10.0%. The growing stock of small shrub species (shrubs with a DBH of less than 10 cm) is dominated by common hazel (Corylus avellana) with 78.3%, while more than 2% is also represented by cornel (Cornus mas), old man’s beard (Clematis vitalba) and elderberry (Sambucus nigra). The results show that the combination of a panel system, a large number of sample plots (3027) and an improved coding system enabled the first comprehensive and objective assessment of tree and shrub species diversity, as well as the presence of non-native species in Slovenian forests.
