ABSTRACTThe long sediment record of Lake Ohrid (FYROM/Albania) turned out to be an important contribution to the knowledge of long-term climate and vegetation dynamics occurred in the Balkans in the last 1.2 million years. The composite DEEP lacustrine record reached a length of 569 m. The cores are studied in the frame of an international cooperation. Palynology was and is carried out on a variety of timescales. The first step was the publication of a skeleton diagram, with samples at about 1600 years resolution (Sadori et al. 2016) covering the last 500 ka and the top 500 m. The age model of this part of the core was based on 10 tephra layers and on tuning of different proxy data to orbital parameters (Francke et al. 2016). At present the whole pollen group, composed by specialists working in several European laboratories, is working on the completion of the skeleton diagram. Specific teams are working to obtain high-resolution data (with samples every about 400 years) on selected periods. Here we present the data obtained for the last interglacial, already multidisciplinary investigated, and with chronology carefully tuned (Zanchetta et al. 2016). The surroundings of the lake during the Eemian were featured by mesophilous communities prevailing on montane ones and by less Mediterranean taxa than expected. Forests were mainly characterized by expansion of Q. cerris type and Q. robur type together with Abies and Pinus. - Francke A., Wagner B., Just J., Leicher N., Gromig R., Baumgarten H., Vogel H., Lacey J.
