Jizera Mountains

Jizera Mountains (Czech: Jizerské hory), or Izera Mountains (Polish: Góry Izerskie; German: Isergebirge), are part of the Western Sudetes on the border between the Czech Republic and Poland. The range got its name from the Jizera River, which rises at the southern base of the Smrk massif. The beech forests within the Jizera Mountains were added to the UNESCO World Heritage Site known as Ancient and Primeval Beech Forests of the Carpathians and Other Regions of Europe, because of their outstanding preservation and testimony to the ecological history of Europe (and the beech family specifically) since the Last Glacial Period.
