Abstract

Primerjali smo rabo zemljišč na katastrskih občinah, na katerih se nahaja Pahernikova posest (Vuhred, Planina, Orlica in Hudi Kot) iz leta 1825 z letom 2017. V vseh analiziranih katastrskih občinah se je delež gozda od 19. do 21. stoletja povečal. Največ se je povečal v katastrski občini Planina in sicer za 46 %. Delež gozda na posesti se je med letoma 1825 in 2014 povečal za 21,4 %. Razlike v sestojnih gostotah in kazalnikih sestojne raznovrstnosti med sestoji, kjer gozd v začetku 19. stoletja ni bil prisoten in sestojih na prvobitnih gozdnih zemljiščih niso statistično značilne. Na celotni posesti znaša lesna zaloga 453,3 m3/ha, v njej prevladuje smreka. Sestojne strukture smo razmejevali na podlagi višinskih pasov s segmentacijo podatkov laserskega skeniranja Slovenije. Višine sestojne strehe in s tem drevesne višine se z večanjem nadmorske višine zmanjšujejo. Fenološke razlike v olistanju prevladujočih drevesnih vrst smo ocenjevali na podlagi satelitskih posnetkov misije Sentinel-2. Ocenjevali smo normirane diferencialne vegetacijske indekse (NDVI) v obdobju od 29. marca do 15. oktobra 2017. Na podlagi razlik v vegetacijskem indeksu NDVI je mogoče ocenjevati fenološki razvoj prevladujočih drevesnih vrst bukve, smreke in macesna v gozdnih sestojih.

Secondary title: Structural diversity of forest stands on Pahernik's forest estate
Secondary abstract: We compared land use in cadastral municipalities where Pahernik property is located (Vuhred, Planina, Orlica and Hudi kot) in year 1825, with land use from year 2017. In all of the analyzed cadastral municipalities, forest area share in land cover grew in the period from 19th to 21st century. We recorded the biggest rise of forest area share in cadastral municipality Planina, specifically 46 %. Forest cover increased for 21 % between 1825 and 2014 on Pahernik property as a whole. Differences in stand densities and in stand diversity indices between the stands where forest was not present in 19th century and the stands on persistent forested lands, were not statistically significant. Average stand volume on Pahernik property is 453,3 m3/ha, spruce is the prevailing species. We delineated stand structures based on height classes, based on segmentation of the data collected with laser scanning of Slovenia. Stand canopy heights and tree heights are decreasing with rising elevation. We estimated leaf-out phenological differences of dominant tree species based on mission Sentinel-2 satellite images. We estimated Normalized Difference Vegetation Indexes (NDVI) in the period between 29th of March and 15th of October 2017. Based on the differences in vegetation indices NDVI, it is possible to estimate phenological development of forest stands for dominant tree species beech, spruce and larch.
