Preface

Tell me the past and I’ll see the future. Confucius

Southeast Europe, the Balkans and not least the southwest Bulgarian Pirin region experienced an eventful natural and cultural history covering a time scale from millenia to the decades of the Younger Past, which has to be decrypted. Information on the Pirin mountains, stored in geo-archives, has been examined using modern methods and with great effort. This monograph seeks to summarize information on landscape and climate development in the region. For the Holocene period, the last 10,000 years or so, the forest and climate history of the mountain regions was reconstructed using pollen analysis of lake sediments and peat. The extensive work of Bulgarian colleagues was analyzed and supplemented with soil surveys. Our examination focused on an archive network in the Alpine timberline zone of the northern Pirins. This network provides tree-ring analyses of centuries-old soil and moraine investigations, firn and ice layers of recent glaciers, and culturalhistory inquiries, as well as analyses of relatively long-time climate data series. Thus, the climate, including its extremes, can be described in relatively high resolution, for the last 500 years. The studies were conducted with the support of the German Research Foundation (DFG) and the German Academic Exchange Service (DAAD), as well as the administration of Pirin National Park. We wish to thank our co-workers and colleagues, namely Sieglinde Gerstenhauer, Alexander Gikov, Bjorn Günther, Dr. Gerhard Helle, Alexander Hennig, Dr. Jürgen König, Dr. Christiana Weber, Thomas Wieloch, Beate Winkler, and students too numerous to be named here, for their assistance with digging and drilling, mapping, sampling and lab analyses. A German version of the book was published first (www.rhombos.de). We thank Mr. Reiser for helping us with the authorisation chores.
