Abstract
Leta 2007 smo ponovili izmero dreves na 2 ha veliki raziskovalni ploskvi na Mašunu. Z analizo podatkov smo ocenili, da se je zgradba sestoja v 56 letih močno spremenila, podobno kot v jelovo-bukovih gozdovih, v katerih so nekdaj prebiralno gospodarili. Analizirali smo spremembe vrstne sestave, porazdelitev dreves po debelinskih stopnjah, ocenilisestojne višine in spremembe lesnih zalog. Delež jelke se je od leta 1973 do danes zmanjšal, medtem ko se je znatno povečal delež bukve. Ocenili smo, da na debelinski prirastek smrek in jelk vpliva osutost njihovih krošenj.

Abstract:
In 2007 we have repeated the measurement of trees on the 2 ha research plot insilver fir and beech stand on Mašun. On the basis of data on succesive measurement in the last 56 years it was estimated that the structure of foreststand has changed similarly as in most silver fir and beech forests in which selection cutting was practised. We made an analisys of the tree speciesstructure, changes of diameter distribution of trees, stand height and changes in growing stock structure. The proportion of silver fir spruce has declined after the year 1973, while the share of beech on the research plot has increased. Defoliation of spruce and silver fir crowns have had an influence on the intensity of the diameter increment.
