Tourbière de la Guette management
The Tourbière de la Guette extends for more than 1.3 km along the Guette river, a tributary of Barangeon. The river once laid a layer of impermeable clay that today allows water to be retained. It is a so-called “topogenous” peatland, that is to say that it is fed by precipitations that fall on the sandy plateau then run off and infiltrate towards the peatland.
The site is home to a number of protected heritage species at the national or regional level. These species are all the more threatened as the Tourbière de la Guette is drying up. Naturally, the peatland evolves on the scale of the geological eras in a wooded wetland. This phenomenon is accelerated by a negative water balance. Thus, the wet moor at Erica tetralix tends to turn into an altered dry moorland at Molinie and Callune. At the same time, the gradual invasion of ligneous plants, in particular birches, is causing a banalisation and an impoverishment of the peatland.
The peatland is recognized as ZNIEFF (Natural Area of Floral and Fauna Ecological Interest) of type I and an integration with the Natura 2000 “Sologne” site. Since 2012 is labeled the Espace Naturel Sensible*.
Today, the Tourbière de la Guette has its management plan realized in 2015, by the Commuanuté de Communes des Villages de la Forêt today Communauté de Communes Vierzon Sologne Berry, via the Site de la Maison de l’Eau, designed in partnership with the town to Neuvy-sur-Barangeon, the CNRS (Centre National de la Recherche Scientifique) and the Orléans ISTO (Institut des Sciences de la Terre), the Conseil départemental du Cher, the ONF, the environmental organization.
Scientists at the peat bog: since 2008, the CNRS and Orléans ISTO have been studying the site. Research is conducted on hydrology, plants, soil, …
