Spremembe sestojne zgradbe v pragozdnem rezervatu Šumik : diplomsko delo - visokošolski strokovni študij

Donik, Mitja (author), Hladnik, David (mentor)

V diplomskem delu smo ocenili sestojno zgradbo pragozdnega rezervata Šumik (19,24 ha). Zgradba gozdnih sestojev je bila ocenjena na osnovi vzorčne mreže,gostote 100*100 m, na kateri smo odmerili 7 arske vzorčne ploskve. Popisali smo dendrometrijske znake živih in odmrlih ter padlih dreves. Glavni drevesni vrsti sta jelka in bukev. V pragozdnem rezervatu smo ocenili povprečno 378 dreves na hektar. Povprečna lesna zaloga v pragozdu je 861m3/ha.Večina dreves (70 %) je zdravih. Od leta 1979, odkar so prvič bile izvedene natančne meritve v osrednjem delu pragozda, se sestojna zgradba ni značilno spremenila.

Abstract

In this thesis we have measured and evaluated stand structures of the virgin forest reserve Šumik (19,24 ha). A sampling net of 100x100 m was set up, and within it a 7 are plots were measured out. Than we`ve registered several characteristics of living and standing or lying dead wood. The dominating tree species are fir and beech. An average of 378 trees/ha was estimated. The average growing stock of living trees is 861 m3/ha. Seventy percent of all living trees are healthy. Stand structure has`t typically changed since first evaluations in virgin forest reserve Šumik in 1979.
