Abstract:V mikrorastiščno pestrem visokokraškem jelovo-bukovem gozdu smo na primeru drevesne vrste smreke ugotavljali zanesljivost ocenjevanja lesne zaloge s tarifami. Referenčne volumne dreves smo ugotovili s pomočjo švicarskih trovhodnih volumenskih funkcij. Ustrezno tarifo smo izbrali po ustaljeni metodi, na podlagi srednjega premera in srednje višine, ki smo jo odčitali iz prilagojene višinske krivulje. Razlike med tarifami posameznih vzorčnih ploskev so do 3 tarifne razrede. Odstopanje med lesno zalogo, ugotovljeno s tarifami in referenčno lesno zalogo za smrekov sestoj, je -2,8 %; pri posameznih ploskvah pa so odstopanja večja, od -7,0 do 8,6 %. Dosedanje (prenizko izbrane) tarife dajo v konkretnem primeru za -18,1 % prenizko oceno lesne zaloge. Sklepamo lahko, da v primeru, če je tarifa za površino (odsek, sestoj) izbrana korektno in reprezentativno, dobimo z njo dobro oceno lesne zaloge tudi na mikrorastiščno pestri površini. Reprezentativni izbor tarife zagotovimo z meritvami na vzorčnih ploskvah, ki dobro predstavljajo površino.

Title:Reliability of growing stock estimation using tariffs in case of a spruce treein forest with varied micro site conditions
Abstract:Reliability of growing stock estimation using tariffs in forest with varied micro site conditions was analysed in case of high karst fi r-beech forest fora spruce tree. Reference bole volumes were calculated with Swiss's three parametric volume functions. Adequate tariffs were selected with standard method, using mean tree diameters and heights, which were calculated from adapted height curves. Adequate tariffs for single sampling plots are different for up to 3 tariff's classes. Difference between growing stock calculated by tariffs and reference growing stock for a spruce tree's stand is-2.8%, whereas for single sampling plots the differences are greater, from -7.0 to 8.6%. The hitherto used tariffs underestimated growing stock by -18.1%in the presented case. Our conclusion is that if tariff for a defi ned area (forest stand or compartment) is representative, with correct method used, the reliability of growing stock estimation is good regardless the varied micro site conditions. Representative selection of tariffs is provided for with measuration on sampling plots that well represent the defi ned area.
