The ZNIEFF of the Vauclair marsh occupies a wide valley oriented to the southwest and whose slopes are wooded. This tuffy marsh, typical of the Plateau de Langres, is the main interest of the vegetation of the area, which includes two protected plant species in Champagne-Ardenne, including Swertia perennis. The entomofauna contains remarkable richnesses, in particular the dragonflies with the Agrion de Mercure protected nationally and at European level (Bern Convention and Habitats Directive) and included on the red list of vulnerable species in France, the Bidentate Cordula, a mountain species rare throughout France and the Ringed Cordula, both included on the red list of Odonates in Champagne-Ardenne. The marsh is very well preserved, but it has not been grazed since the land consolidation (around 1990).
