À propos
The Bois de la Côte Znieff covers one of the most important sites in the central part of the Haute-Marne département. This steep hillside, on the edge of the Marsois forest massif, overlooks the Traire valley and the hamlet of Nogent-le-Bas to the south-west of Nogent-en-Bassigny. The plateau edge and slope feature montane-type woodlands: maple stands on large boulders (Lunario-Acerion) and toothed beech forests. Particular fern vegetation (scolopendre, polypode vulgaire, doradille) develops on the hard limestone faces. The maple grove is the most typical in the whole department: the trees and shrubs present emphasize the particularly cold microclimate that prevails here (beech, plane maple, sycamore maple, mountain elm, elderberry, bois-jolis).
It is home to the lunaria perennial, a rare pre-alpine species with only four localities in Haute-Marne, which is protected at regional level (the Champagne-Ardenne stations, along with those in Bourgone, are the only known lowland localities in France) and is on the red list of endangered plants in Champagne-Ardenne. Other interesting species include the two damselflies (rare on limestone in Haute-Marne) and the impatient cardamine.
The site has been protected by an Arrêté de Protection de Biotope since 1991. Highlighting the edge of the hillside, Bois de la Côte plays an important role in the landscape. The limestone walls and rocky outcrops also give it a certain geomorphological and geological importance. The site, proposed under the Habitats Directive, is in very good condition and is the only remaining intact area of the large Marsois forest massif, which was completely razed and afforested in the 1980s.
