New renaturation project in Lower Saxony promotes biological diversity in peat bogs

Raised moors are not only important for climate protection and the water balance of landscapes. They also provide a habitat for adapted and therefore rare and endangered animal and plant species. If these areas are drained and dismantled, homogeneous and largely vegetation-free areas remain. In the “Insects revitalize moors” project, pitted areas in the “Totes Moor” nature reserve in the Hanover region are therefore not only to be rewetted, but also to be repopulated with plants typical of high moors. So the insects of the raised bogs can return. The Federal Ministry for the Environment, Nature Conservation and Nuclear Safety is funding the project, which is supported by the Federal Agency for Nature Conservation (BfN), with around 1.8 million euros in the federal program for biological diversity. Federal Environment Minister Svenja Schulze: “In Germany, more than 90 percent of the Bog areas as drained – they were drained for peat extraction. As a result, they can no longer develop their natural functions. Wet bogs serve as water reservoirs and as a habitat for species that have become rare, they also store CO2 and thus play an important role not only for nature but also for climate protection. That is why we want to promote the protection of the moors with new renaturation methods so that biodiversity can be restored and preserved. ”BfN President Prof. Dr. Beate Jessel: “In the“ Insects revitalize moors ”project, the drained, pitted areas are rewetted and ‘inoculated’ with peatland plants from the immediate vicinity. In this way, we create the prerequisites for the typical bog to spread over the entire area again and for valuable habitat to be reclaimed for the insects and other typical bog species that are specially adapted to high bogs. ” In the project area in the “Totes Moor” nature reserve near Neustadt am Rübenberge, peat is currently still being extracted. Peat removal is followed by the prescribed rewetting; Subsequently, without further renaturation measures, mostly only species-poor, almost flower-free and insect-free habitats develop on the areas, which will remain stable for many decades Create high bog rich in insects. For this purpose, the soil is designed in relief and “inoculated” with planting material from so-called “healthy skin” areas that have never been peeled off. A bog can develop with the microhabitats necessary for insects such as flowers, larval forage plants, oviposition and wintering habitats. The measures are aimed at the entire community of the diverse raised bog complex: Moist heaths and transitional bogs as well as the juxtaposition of dry bulbs and wet gullies provide a habitat for many highly specialized and often rare species. The Hanover region is initially testing the planned measures on seven areas in different stages of development after peat removal and with different site conditions. These areas are not only recently pitted, vegetation-free areas, but also areas that were rewetted up to 30 years ago and on which no typical plant species and structures that are important for insects have so far developed. Leibniz Universität Hannover is investigating the effect of the “vaccinations” and developing recommendations for larger areas. The most successful renaturation measures will then be implemented on up to 50 hectares. The results of the project will primarily be discussed with experts in raised bog renaturation. The Steinhuder Meer Nature Park offers excursions and events for the general public.

The federal program for biological diversity The implementation of the national strategy for biological diversity (NBS) has been supported by the federal program for biological diversity since 2011. Funding is given to projects that are representative of the whole of the state within the framework of the NBS or that implement this strategy in a particularly exemplary manner. The funded measures help stop the decline in biological diversity in Germany and turn it into a positive trend in the medium to long term. They serve the protection and sustainable use as well as the development of biological diversity and go beyond the legally required standards. Acceptance-building measures of information and communication help to increase social awareness of biological diversity.
