The La Guette station (ICOS code FR-LGt) is a peatland located in Neuvy sur Barangeon (Sologne) at about 200 Km south of Paris and 80 Km south of the Université d''Orléans. It is a acid fen that is cut at the output by a road. Along the road, a draining ditch was dug to avoid flooding of the road. This ditch has a lower altitude than any point in the peatland, and thus increases the speed at which water flows out of the system. This disturbance has promoted the invasion of the site by Molinia caerulea (L.) Moench (gramineae), followed by Pinus sylvestris L., and Betula sp. invasion. In addition, to vegetation change, such a disturbance has modified the hydrology of the site. The ecological engineering works undertaken in 2014 aimed to reduce the effect of the ditch on at least the downstream part of the site. The eddy covariance station is located in the middle part of the peatland, where the restoration works may not have any effects. The typical fen vegetation remaining consists in 11 species of Sphagnum sp., Eriophorum angustifolium Honck., Rhynchospora alba (L.) Vahl, Gentiana pneumonanthe L., Eleocharis sp., Scirpus sp., Ericaceous shrubs are also well represented with Calluna vulgaris (L.) Hull and Erica tetralix L..
