The present study sought to characterize the soils of typical sites in the Flysch region around the Tegernsee and to evaluate their suitability for the growth of European beech. For this purpose 7 soil profiles located in the higher mountain zone were sampled. 3 site factors were taken into consideration while selecting the sample plots in order to allow comparison of beech. vs. conifer-dominated stands, sandy vs. marly substrates and northern vs. southern slopes. Representative soils were analyzed with standard laboratory procedures to determine their chemical and physical characteristics.On deep and loose (Podsol-) Braunerde soils (dystric cambisols) rich in humus and derived from sandstone parent rock, beech occurs regularly in the study area and grows well on both slope positions despite of the acidic reaction and low base saturation in the mineral soil (<10%). Neither strong acidity nor low base cation and phophorus concentrations exclude the species. Beech also grows vigorously on well-drained non-hydromorphic soils derived from marly sediments and siltstones or claystones. Up to its altitudinal limit, only periodically wet and cold, insufficiently drained gleysols appear to severely limit beech growth although these soils are comparably rich in nutrients.
