Norway spruce forests survived in inaccessible localities of the montane belt and around the upper treeline at the end of the Mumlava and Labe valleys, Dlouhý důl, Modrý důl, Obří důl, and Jelení důl. Significant plants are ferns (the mountain lady-fern, malefern, broad buckler-fern, holly fern), grasses (the hairy small-reed, wavy hair-grass) and bryophytes. Tall herb meadows with hairy chervil, blue sow-thistle, monkshood, white butterbur, or large bitter-cress can be found around forest streams and springs. Significant animals are mainly snail Semilimax kotulae, springtail Tetrodontophora bielanensis, eight-toothed spruce bark beetle, ground beetles Carabus sylvestris and C. linnei, daddy-longleg Ischyropsalis belwigii, Tengmalm's owl, firecrest and goldcrest, crossbil, jay, nutcracker, alpine shrew, red squirrel, and red deer.
