Gozdna meja
Gozdna meja je nadmorska višina, do koder seže strnjen gozd. Nad to mejo drevesa tako gosto ne morejo rasti zaradi različnih dejavnikov, običajno zaradi prenizkih temperatur. Gozdna meja na območju Slovenije je med 1600 do 1800 m nadmorske višine.
Macesen (Larix decidua) je drevo, ki raste v gorah Srednje Evrope, v Alpah in Karpatih. Je zelo odporen na nizke temperature, vse do -50°C. Običajno raste do zgornje gozdne meje, ki je v Alpah vse do 2000 m nadmorske višine. Rad ima sušna tla in dobro osončenost.
Ruševje raste nad gozdno mejo, vendar ga najdemo glede na klimatske razmere tudi v nižje ležečih legah – običajno od 1000 – 2200 m.

Tree line
The tree line is the edge of the habitat at which trees are capable of growing. Beyond the tree line, trees cannot tolerate the environmental conditions like too low temperatures. The tree line in Slovenia is between 1600 to 1800 m of elevation.
Larix decidua (European larch) is a species of larch native to the mountains of Central Europe. It is very cold tolerant, able to survive temperatures down to -50°C, and is among the tree line trees in the Alps reaching 2000 m altitude. It grows on well-drained soils, avoiding waterlogged ground.
Pinus mugo (mountain pine) is native to high elevation habitats. Regarding the local climate it is usually found on the elevation from 1000 – 2200 m.
