Three isolated massifs in the Sudetes, Central Europe, are elevated sufficiently high to allow for the development of the treeline ecotone. These are the Karkonosze/Krkonoše in the West Sudetes and Hruby Jeseník and Masyw Śnieżnika/Králický Sněžnik in the East Sudetes.

The upper limit of closed tree stands (i.e. timberline) is located at c. 1250 m a.s.l. on average in the Krkonoše, but with significant variability spanning more than 500 m. In the East Sudetes the respective elevation is higher, above 1300 m a.s.l., and the variability is smaller.

While temperature is the primary factor governing the uppermost tree stands, second-order climatic factors play an important role in shaping treeline ecotone position, particularly wind and snow accumulation patterns.
