The territory of Normandy offers biodiversity that participates in its identity and is an important asset for its economic and social development.In fact, the preservation of biodiversity represents an asset in the attractiveness of the territories by maintaining a quality living environment for the inhabitants and by the development of economic activities linked in particular to the tourist attraction of the region.The hillsides and limestone lawns are among the most emblematic natural environments in the region.Reknown for their great ecological interest, they welcome remarkable, often rare and threatened fauna and flora unique in the region. In order to preserve the natural heritage, the ecological functions and the landscapes that make hillsides and limestone lawns typical, the Conservatoires d’espaces naturelles de Normandie wanted to mobilise all the actors in these areas around a regional programme of joint actions: the Regional Programme of Action for Limestone Hills and Lawns.The particular interest of limestone habitats in hosting remarkable biodiversity is highlighted in the Regional Ecological Coherence Schemes (SRCE) of the two territories. For the high-Norman territory, a neutro-calciculture subtle has been specifically defined to maintain the calciculture media and their continuity. It is the sectors identified in this sub-trame that constitute the bulk of the programme’s action area for the upper-Norman part.For the lower-Norman territory, the SRCE has defined a sub-trame "open more generally, integrating all limestone habitats. There is no precise mapping of the positioning of the slopes and limestones in this part of the territory, but some geographical areas are however well identified locally.The lawns have an unstable character, more or less perceptible at human scale, which leads, in the absence of pastoral disturbances, to the development of preforestry vegetation generally forming part of the potentialities of neu-calciculture forests.
