Privately owned silver fir forests near Lovrenc na Pohorju

V avgustu 2015 in marcu 2016 so izvedli polno izmero gozdnih sestojev v odsekih 163D in 163B, ki se nahajata v gozdnogospodarski enoti Lovrenc na Pohorju, v rastiščno gojitvenem razredu jelovja na rodovitnejših rastiščih. S tukajšnjimi zasebnimi gozdovi se tradicionalno gospodari na prebiralen način, pogosti pa so tudi manjši smrekovi nasadi. Določili so trenutno debelinsko strukturo, temeljnico, lesno zalogo, drevesno sestavo in dimenzijsko razmerje dreves. Različne drevesne vrste se različno porazdeljujejo po debelinskih stopnjah % jelka in listavci so bliţje prebiralni strukturi, smreka pa prehodni, razen v smrekovih nasadih, kjer se smreka in druge drevesne vrste porazdeljujejo v normalni porazdelitvi, značilni za enodobne sestoje. V zadnjih 50 letih so ugotovili močno naraščanje lesne zaloge (s 316 m3/ha na 603 m3/ha) in naraščanje deleţa listavcev (s 5,7 na 11,7 %). Z obdelavo lidarskih podatkov so prikazali digitalne modele drevesnih krošenj.In August 2015 and March 2016 we did a full calipering of forest stands in sections 163D and 163B, which are located in the Lovrenc na Pohorju Forest Management Unit, in silver fir growing sites. The local private forests are traditionally harvested by selection system, smaller spruce (Picea abies) plantations are also common. Current tree diameter structure, basal area, growing stock, species structure, and tree dimension ratio (h/d factor) were determined. Different tree species are distributed differently throughout the diameter levels. Fir and deciduous tree species seem closer to selection forest diameter structure, while spruce diameter structure seems more intermediate. Exceptions are the spruce plantations, where all present tree species have normal diameter distribution, typical of even-aged forest stands. In the last 50 years there was a strong increase in growing stock (from 316 m3/ha to 603 m3/ha) and increase in proportion of deciduous tree species (from 5.7 to 11.7 %). Through processing of LIDAR data, digital models of tree canopies were made
