Abstract

Delo predstavlja analizo dinamike rasti macesna (Larix decidua Mill.) na strmih pobočjih v varovalnem gozdu v dolini Kamniške Bistrice v višinskem pasumed 1300 m n. v. in 1400 m n. v. V analizo so bila zajeta drevesa s skrajnih rastišč, kjer macesen skupaj z navadnim slečnikom tvori združbo Rhodothamno chamaecisti - Laricetum deciduae. Za primerjavo rastnih značilnosti je bila opravljena še analiza dinamike rasti macesna v gospodarskem gozdu na primerljivi nadmorski višini, na planoti Velika planina,kjer je macesen primešan sestojem bukve in smreke. Ugotovljeno je bilo, da macesen na skrajnih legah prirašča enakomerno, vendar občutno počasneje kot na boljših legah. Najstarejša drevesa na najbolj izpostavljenih legah dočakajo visoke starosti, tudi preko 200 let. Socialni razred in utesnjenost krošnje sta dejavnika, ki pomembno vplivata na debelinsko in višinsko rast. Za večji del macesnov ni bila potrjena odvisnost njihovega radialnega priraščanja od klimatskih spremenljivk.

Secondary title:	Growth of European Larch (Larix decidua Mill.) on steep slopes in Kamniška Bistrica
Secondary abstract:	The thesis represents an analysis of European larch (Larix decidua Mill.) growth dynamics on steep slopes of the Kamniška Bistrica valley in a protective forest in the zone between 1300 m and 1400 m above sea level. The analysis has included trees in extreme site conditions, where European larch together with Dwarf Alpenrose (Rhodotamnus chamaecistus) creates the vegetation community Rhodothamno chamaecisti- Laricetum deciduae. For comparison of acquired data an analysis of European larch growth in a managed forest at comparable elevation above sea level on the Velika Planina plateau, where European larch is mixed into beech and spruce stands. It has been established that European larch on exposed sites has a steady growing, howeverit is much slower than on more favourable sites. The oldest trees on the most exposed sites reach quite an advanced age, also over 200 years. The social class and crowding of the tree canopy are factors which have significant impact on radial and height growth. The influence of climate factors on tree ring width was insignificant for the majority of larch trees.
