| Zusammenfassung |
| Holocene climate fluctuations and human activity since the Neolithic have
shaped present-day Mediterranean environments. Separating anthropogenic
effects from climatic impacts to better understand Mediterranean
paleoenvironmental changes over the last millennia remains a challenging
issue. High-resolution pollen analyses were undertaken on two cores from the
Palavasian lagoon system (Hérault, southern France). These records allow
reconstruction of vegetation dynamics over the last 4500 years. Results are
compared with climatic, historical and archeological archives. A long-term
aridification trend is highlighted during the late Holocene, and three
superimposed arid events are recorded at 4600–4300, 2800–2400 and
1300–1100 cal BP. These periods of high-frequency climate variability
coincide in time with the rapid climatic events observed in the Atlantic
Ocean (Bond et al., 2001). From the Bronze Age (4000 cal BP) to the end of
the Iron Age (around 2000 cal BP), the spread of sclerophyllous taxa and
loss of forest cover result from anthropogenic impact. Classical Antiquity is
characterized by a major reforestation event related to the concentration of
rural activity and populations in coastal plains leading to forest recovery
in the mountains. A major regional deforestation occurred at the beginning of
the High Middle Ages. Around 1000 cal BP, forest cover is minimal while the cover of olive, chestnut and walnut expands in relation to increasing human
influence. The present-day vegetation dominated by Mediterranean shrubland
and pines has been in existence since the beginning of the 20th century. |
