Zgornja drevesna meja nad prelazom Presedljaj (1700 m), Kamniško-Savinjske Alpe. Macesnov gozd prehaja v ruševje. Ruševje raste nad gozdno mejo, vendar ga najdemo glede na klimatske razmere tudi v nižje ležečih legah – običajno od 1000 – 2200 m. Macesen (Larix decidua), ime za evropski macese, je drevo, ki raste v gorah Srednje Evrope, v Alpah in Krapatih, deloma tudi v nižinah severne Poljske in južne Litve. Macesen je zelo odporen na nizke temperature, vse do -50°C. Običajno raste do zgornje gozdne meja, ki je v Alpah vse do 2000 m nadmorske višine, običajno na nadmorskih višinah od 1000-2000 m. Rad ima sušna tla in dobro osončenost.

The Tree lines above the mountain pass Presedljaj (1700 m), Kamnik-Savinja Alps The larch trees forest is passing to mountain pine (Pinus mugo). Pinus mugo or mountain pine, also dwarf mountain pine is a species of conifer, native to high elevation habitats from southwestern to Central Europe. Regarding the local climate it is usually found on the elevation from 1000 – 2200 m. Larix decidua, common name European larch, is a species of larch native to the mountains of Central Europe, in the Alps and Carpathian Mountains, with disjunctive lowland populations in northern Poland and southern Lithuania. Larch tree is very cold tolerant, able to survive winter temperatures down to at least -50°C, and is among the tree line trees in the Alps, reaching 2000 m altitude, though most abundant from 1000–2000 m. It only grows on well-drained soils, avoiding waterlogged ground.
