LIFE PEAT RESTORE Greenhouse gas exchange on degraded and rewetted peatlands

LIFE 15 CCM/DE/000138

Visit us at: https://life-peat-restore.eu

Partners:

Co-Financiers:

Drainage promote the decomposition of peat, which results in high emissions of carbon dioxide (CO2) and nitrous oxide (N2O)

Rewetting & Restoration of drained and degraded peatlands reduces Greenhouse Gas (GHG) emissions and could mitigate effects of the climate change

Higher water tables can also promote the methanogenesis and the emissions of methane (CH4)

GHG-Monitoring is needed for Estimation and Evaluation of the climate effect of restoration measures

First Results

Contact details: Nature and Biodiversity Conservation Union, Charitéstr. 3, 10117 Berlin, Germany, Andreas Herrmann: [email protected], Letícia Jurema: [email protected], www.life-peat-restore.eu/en

Project Sites

Manual Chamber Method (acc. to ALM et al. 2007, DRÖSLER et al. 2005) with transparent and opaque chambers equipped with a cooling system

3-5 spatial repetitions per site Automated in-situ CO2-measurements (RECO, NEE) by Infrared gas

analyzer (Li-6400; Li-810 COR, EGM5) Manual and automatic sampling for CH4 and N2O analysis in the

laboratory Additional measurements of soil temperature, soil moisture,

photosynthetic radiation, water table, forest inventory data and climatic parameter)

2-4 weekly measurement campaigns throughout the vegetation period with several single measurements at different radiation and temperature conditions per measurement day

Flux calculation by using the ideal gas equation; Δc was calculated by linear regression
