TOWARDS THE UNDERSTANDING OF THE PRESENT-DAY HUMAN IMPACT ON PEATLAND DEPOSITS FORMED SINCE THE LATE GLACIAL: A “RETROSPECTIVE” AGE–DEPTH MODEL OF THE GREL RAISED BOG (POLISH INNER CARPATHIANS)

ABSTRACT During the last 60 years, thickness of Grel peatland deposits (Polish Inner Carpathians), was decreased twice: from about 7.4 m in 1962, to 3.9 2019. Pollen analyses peat performed 1962 (Koperowa 1962) and 2019 (this study) showed that have accumulated since Oldest Dryas Stadial up present day. Comparative analysis both palynological profiles carried out, which exhibits a high consistency percentage pollen several taxa for 10 horizons occurring profiles. Based on age–depth curve made new profile, modeled age above-mentioned compliance levels obtained based this age, “retrospective” model elaborated Koperowa’s profile. The compaction sediments did not occur proportionally entire sequence. conducted research indicates contemporary human activity may significantly affect whole length profiles, only their upper parts, as previously considered. reconstruction palaeoenvironment (palaeoclimate) multiproxy is capable precisely document phenomenon.
