Hofer 2012: Comparison of Three Different Methods for the Determination of Climate Relevant Gas Exchange of Mires
Summary:
Theme X. Peatland carbon budgets and greenhouse gas (GHG) fluxes
SUMMARY
The article compares different methods for determining greenhouse gas emissions of raised bogs in Lower Saxony, Germany. A joint venture project between Volkswagen Leasing GmbH and NABU (German Society Nature Conservation) aims mire protection and the reduction of CO2-emissiones for the climate protection at the same time. In order to reach the aim depleted peat fields and areas previously used for agriculture are rewetted in a mire protection area. Our engineering company for ecology, environmental protection and landscape management, Hofer & Pautz, BGB, analyzed the potential savings of climate relevant gases from three mires:
– Theikenmeer, district Emsland
– Sauerbach, district Gifhorn
– Lichtenmoor, district Nienburg
We applied two types of methods to estimate the annual CO2emission. In the first one the loss of organic matter was quantified based on
1. a comparison between new and ancient peat stratigraphical profiles. In the second one
2. emission factors were defined for each site based on their mire site type and land-use class (Höper, 2007) or based their stage of humidity (Couwenberg et al., 2008)
