Abstract

V raziskavi smo preverjali uporabnost aplikacije MOTI pri ocenjevanju sestojnih parametrov na zasebni gozdni posesti Lešje, ki meri 26,14 ha. Primerjali smo porabo časa med aplikacijo MOTI in klasičnimi inventurnimi metodami in ocenili velikost vzorca za zanesljivo oceno sestojnih parametrov. Na 160 stojiščih (mreža 40 % 40 m) je bila izvedena izmera sestojnih parametrov z mobilno aplikacijo MOTI. Na naključno izbranih 50 stojiščih so bile izvedene klasične meritve sestojne temeljnice. Na dodatnih naključno izbranih 50 dvoarskih ploskvah smo izmerili prsne premere vseh dreves nad meritvenim pragom (prsni premer % 10 cm), da bi ocenili debelinsko strukturo gozdnih sestojev. Primerjava ocen sestojnih parametrov med metodo MOTI in kotnoštevno metodo kaže, da se večina vrednosti značilno razlikuje, le za vrednosti povprečne lesne zaloge ter deležev jelke in smreke v lesni zalogi razlik nismo odkrili. Relativni vzorčni napaki za oceni sestojne temeljnice in lesne zaloge z metodo MOTI sta znašali 4,9 % in 5,5 %. Poraba časa za meritve z aplikacijo MOTI je večja kot za klasične meritve sestojev s kotnoštevno metodo. Aplikacija MOTI je uporabna za lastnike gozdov in operativne gozdarje, ker omogoča hitro in zanesljivo oceno stanja gozdov ter neposreden izračun vrednosti sestojnih znakov.

Secondary title:	ǂThe ǂuse of MOTI mobile application for evaluating stand parameters on the Lešje private forest property
Secondary abstract:	The study examined the usefulness of the application MOTI for the estimation of stand parameters at the Lešje private forest property covering 26.14 ha of forest. The time consumption was compared between measurements with the MOTI application and the classical Bitterlich method, and the number of measurements required for a reliable estimation of stand parameters was estimated. Stand parameters were measured on 160 plots (40 x 40 m grid) using the mobile application MOTI. The classical measurements of stand basal area were done on 50 randomly selected plots. On another 50 randomly selected plots, the diameter at breast height of all trees above the measurement threshold of 10 cm was measured in order to estimate the diameter distribution of forest stands. The comparison of stand parameters between the MOTI and the classical Bitterlich method showed that most values were significantly different, except for the average values of stand volume and the shares of silver fir and Norway spruce. The sampling errors for stand basal area and stand volume amounted to 4.9% and 5.5%. It was ascertained that the measurements using the MOTI application were more time consuming than the measurements using the classical method. The application MOTI is, however, a useful tool for private forest owners and forestry practitioners since it enables a relatively fast and reliable assessment of stand characteristics on forest property or in stands in general and since it immediately shows the evaluated values of stand parameters.
