| description | <p>Anthropogenic activities have exerted strong influence on ecosystems worldwide, particularly since 1950 CE. The local impact of past human activities often started much earlier and deserves detailed study. Here, we present an environmental record from a 278 cm long sedimentary core from Lake Höglwörth (Bavaria, Germany). Sedimentological and geochemical parameters indicate that the organic-rich bottom sediments of the record consist of peat that formed prior to <span class="inline-formula"><math xmlns="http://www.w3.org/1998/Math/MathML" id="M1" display="inline" overflow="scroll" dspmath="mathml"><mrow><msubsup><mn mathvariant="normal">870</mn><mrow><mo>-</mo><mn mathvariant="normal">160</mn></mrow><mrow><mo>+</mo><mn mathvariant="normal">140</mn></mrow></msubsup></mrow></math><span><svg:svg xmlns:svg="http://www.w3.org/2000/svg" width="39pt" height="17pt" class="svg-formula" dspmath="mathimg" md5hash="82944dc0b29bd4229010117534751a7a"><svg:image xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="egqsj-72-219-2023-ie00001.svg" width="39pt" height="17pt" src="egqsj-72-219-2023-ie00001.png"/></svg:svg></span></span> CE, when lake sediments started to accumulate.
