Two pedunculate oak (Quercus robur L.) stands established at the beginning of the 20. Century in the forest district “Kottenforst” (Niederrhein) were investigated. One stand was planted with saplings of 2 to 3 m hight (“Heister”) in a 5 m triangle plot and the other was sown in rows with a distance of 2 m between the rows. The report describes site conditions, establishment, chronicle, stand measurement and technological properties of the wood of the two stands.Compared to the sown stand the superior growth of the “Heister”-planting was previously regarded as the effect of a more spacious growing pattern and the positive effects of the naturally regenerated mixed tree species.Phenomenological observations and investigations of the chloroplast DNS revealed that the oaks of the two stands are of different origin. The “Heister”-planting oaks are of Slavonian and the sown oaks of Western European provenance. Differences in the growth rate are due to different provenances and not caused by different establishment and management of the two stands. Oak stands of the same origin show only little differences either sown or planted as “Heister”.
