These forests are dominated by Pinus sylvestris, in places with Quercus petraea agg. in the understorey. They occur on serpentine slopes in two areas in the Bohemian-Moravian Uplands, namely the middle Jihlava valley and the Želivka valley. They are situated at lower altitudes and in drier regions than most other serpentine areas in the Bohemian Massif. The herb layer of these pine forests contains several species typical of dry grasslands and several isolated occurrences of presumably relictual montane species. The serpentine specialists Armeria elongata subsp. serpentini and Asplenium cuneifolium are common. In places, the relictual dealpine grass Sesleria caerulea dominates the herb layer.
