The goals of this study were to describe and compare the distribution of soil properties in spruce and beech forests in altitude transects (Jizera Mountains, Czech Republic) with known environmental temperature, precipitation, and vegetation gradients. Soil samples were collected from soil pits in a surviving nature-close beech forest, production spruce forest, and in the top dead forest area with grass cover. Soil pH, effective cation exchange capacity (eCEC), A400/A600, contents of cations in the sorption complex, available Ca, Mg, K and P, pseudototal levels of Ca and Mg, and two differently extracted Fe and Al forms contents were determined. The soils were strongly acid with low eCEC. Soil chemical properties of the most affected top mountainous parts were in some aspects more favourable than lower parts (binding of potentially toxic Al in organic matter, slightly higher pH). Nevetheless, they are still endangered by acidification (high leaching of base cations, especially Mg). The more natural beech forest had more favourable soil properties than planted spruce ones.
