In this paper the results of a palynological investigation of a 120 m deep borehole in the Tenaghi Philippon, Macedonia (Greece) are given. These data show that during the Holocene mainly an oakwood forest was present. In the most recent part of the Holocene Fagus and Abies were also present. During the climatic extremes of the Weichselian an open vegetation existed. During the early interstadials a forest with Quercus, Fagus and Carpinus existed, whereas in the later interstadials stands of Pinus predominated. In the Late Glacial a not very dense oak forest was of some importance.
