M. & Sobr M.: The Lateglacial and Holocene in Central Europe: a multi-proxy environmental record from the Bohemian Forest, Czech Republic. Boreas. 10.1111/bor.12126. ISSN 0300-9483. The Hercynian mountain ranges were islands of mountain glaciation and alpine tundra in a Central European ice-free corridor during the Late Pleistocene. Today they are notable areas of glacial landforms, alpine-forest free areas, peatlands and woodlands. However, our knowledge of the Lateglacial and early Holocene environmental changes in this region is limited. We present a new multi-proxy reconstruction of a mid-altitude environment in the Bohemian Forest spanning this period. A core (5.2 m length) in the Cern e Lake cirque (1028 m a.s.l.) was sub- jected to lithological, geochemical, pollen and macrofossil analysis supplemented by two optically stimulated luminescence (OSL) and 10 AMS radiocarbon dates. We determined the impact of regional and supraregional cli- mate changes on the environment. The two most significant changes in sedimentation during the Lateglacial (17.6 and 15.8–15.5 cal. ka BP) were synchronous with regional glacial chronostratigraphy. Unlike Central European mountain ranges, in the Bohemian Forest the Younger Dryas was not coincident with glacier re-advance, but was a dry, cold episode with low lake levels, which prevailed until the early Preboreal.
