Lower subalpine forest , 450-1,000m , is characterized by deciduous or mixed forest. The fragments of forests similar to natural complexes of pine-fir-beech with admixture of larch, sycamore maple and lime occur near the Szklarski waterfall, in the Jagniatkowski complex, and Chojnik Mountain. Particular species of trees have different climatic requirements. The lowest parts are covered with oak and ash, up to 500m . On the level of 500-600m occurs pine; in the higher parts, up to 800m , there occurs European larch; and above 800m, fir and beech. Despite of transformation of the basic tree vegetation, the same form of undergrowth survived. There occurs: daphne mezereum, red elderberry, hazel, platanthera bifolia, sweet woodruff, herb paris, cranberry, wood sorrel, chickweed wintergreen, Common Cow-wheat and lily of the valley. The parts over 800m are mainly covered with grasses, purple small-reeds, cranberries, and willow gentian. In highlighted places, on meadows, and along roads, there occurs: spotted orchid, bugleweed, yellow archangel, arnica montana, sword-leaved helleborine, rosebay willowherb, groundsel, and foxglove. Along riversides, there occurs white butterbur. Pine forests are rich in spruces, which are permanently weakened by atmospheric factors. Frayed roots are easily infected by harmful fungus and insects. The most damaging is honey mushroom, with edible specimen, which grows in pulp, between the bark and timber, causing the death of tree. The other damaging fungus is bracket fungus, which destroys roots and trunks from the inside. The honey mushroom devastates the tree within a few months, and the bracket fungus, within a few years, as a result of mechanic changes in wood structure.
