Rewetting does not return drained fen peatlands to their old selves

New Paper in Nature communications


Kreyling, J., Tanneberger, F., Jansen, F., van der Linden, S., Aggenbach, C., Blüml, V., Couwenberg, J., Emsens, W-J, Joosten, H., Klimkowska, A., Kotowski, W., Kozub, L., Lennartz, B., Liczner, Y., Liu, H., Michaelis, D., Oehmke, C., Parakenings, K., Pleyl, E., Poyda, A., Raabe, S., Röhl, M., Rücker, K., Schneider, A., Schrautzer, J., Schröder, C., Schug, F., Seeber, E., Thiel, F., Thiele, S., Tiemeyer, B., Timmermann, T., Urich, T., van Diggelen, R., Vegelin, K., Verbruggen, E., Wilmking, M., Wrage-Mönnig, N., Wołejko, L., Zak, D., Jurasinski, G.


Peatlands have been drained for land use for a long time and on a large scale, turning them from carbon and nutrient sinks into respective sources, diminishing water regulation capacity, causing surface height loss and destroying biodiversity. Over the last decades, drained peatlands have been rewetted for biodiversity restoration and, as it strongly decreases greenhouse gas emissions, also for climate protection. We quantify restoration success by comparing 320 rewetted fen peatland sites to 243 near-natural peatland sites of similar origin across temperate Europe, all set into perspective by 10k additional European fen vegetation plots. Results imply that rewetting of drained fen peatlands induces the establishment of tall, graminoid wetland plants (helophytisation) and long-lasting differences to pre-drainage biodiversity (vegetation), ecosystem functioning (geochemistry, hydrology), and land cover characteristics (spectral temporal metrics). The Paris Agreement entails the rewetting of 500,000 km2 of drained peatlands worldwide until 2050-2070. A better understanding of the resulting locally novel ecosystems is required to improve planning and implementation of peatland rewetting and subsequent management.

Greenpeace learns about importance of peatlands

A delegation from Greenpeace Germany visited the Greifswald Mire Centre on August 26. with plenty to learn about peatlands. Staff of the University and the Michael Succow Foundation brought them up to date and left them with new questions. Their visit to the 'Karrendorfer Wiesen' peatland in pouring rain was especially eventful. Dr. Nina Seifert of the Succow Foundation gave an introduction to the location's history before Daniel Köhn from Rostock University demonstrated the greenhouse gas measurements on the two field sites of the WETSCAPES project. At the end of the day everyone was thoroughly soaked and all agreed on the importance of field research and the first hand experience of field conditions for the understanding of these ecosystems.

Masterstudent wins Sustainability Award 2019

MSc. Alexander Seliger was awarded the University of Greifswald's Sustainability Award for his thesis on options when replacing non-native spruce stands with native species in the beautiful Western Pomerania Lagoon Area National Park in north-eastern Germany. The award with a 500 € prize is handed out anually by the University's Rectorate and Sustainability Officer.

Thesis title:

Management options for the conversion of non-native coniferous forest patches towards more natural species composition in the Western Pomerania Lagoon Area National Park (Germany)

The Thesis was supervised by Jürgen Kreyling and Michael Manthey.

REPEAT at the climate conference

The research project REPEAT was has been presented at two peatland-related events at the UNFCCC climate confererence COP24 in Katowice. On December 6th, a side event in the German Pavilion showcased peat fires and peatland rewetting. On December 11th, the Climate Hub focused on food from drained peatlands - from gouda cheese to palm oil cookies. Hans Joosten, Wiktor Kotowski and Franziska Tanneberger presented the project.

See the tweets of the Greifswald Mire Centre from COP24.

WETSCAPES on television
