PhD project
Habitat Harz: The Environmental History of a Mountain Area and its Foothills.
Main aims of the project are to elucidate human impact on the vegetation in detail and to cast more light into woodland and charcoal usage by human. Moreover to separate natural and anthropogenic influences to obtain a detailed history of the vegetation dynamics and the climate since the early Holocene focusing on the late Holocene.
Therefore my investigation is based on four palaeobotanical studies on different archives, altitudes and timescale in the Harz Mountains:
  • Charcoal analyses on kilns above 600 m a.s.l. (kiln- and dendro-anthracology; Modern Times)
  • Charcoal analyses on archaeological excavations (archaeo- and dendro-anthracology) in combination with the analyses of botanical macro-remains in the middle Harz (Middle Ages)
  • Palynology of peat-bog cores in the upper Harz (Early to late Holocene)
  • Stable isotope geochemistry on a peat profile (since the Iron Age)
In general, wood charcoal analysis provides site-related information on species occurrence and woodland composition while pollen analyses gives the possibility of reconstructing local and/or regional vegetation diachronically. But for separating between the climate signal and human activity a comparison with non botanical proxies is essential. For the first time in the Harz we apply a high resolution multi-proxy analyses on a peat profile to elucidate climate variability (temperature and hydrology) and to compare it with human activity. This investigation is in cooperation with the Institute of Bio- and Geosciences – IBG 3: Agrosphere (Research Centre Jülich) and based on the analyses of d 13Ccellulose and 18Ocellulose from Sphagnum L. and of palynology (transfer functions, cooperation with Dr. Norbert Kühl, Bonn). Additionally flux-rate, the humification and loss on ignition were measured.
