The earthworks necessary origin of seeds remains an issue to examine for a better agricultural management of land in depth. It is widely recognized that site- or for tourism activities sometimes require specific seeds can better withstand the heavy modelling of the slopes, in a fragile conditions, sometimes extreme, of mountain environment. areas, especially at higher elevations. The Restoration of the vegetation at the end of tests conducted in the Pyrenees and in the the earth moving works is now a common Eastern Alps showed the superiority of local practice. Current methods are very different seeds compared to those obtained from plants from those used a few decades ago. All over not adapted to the hard climatic conditions of the Alps, soil management is treated with more high-altitude environments. attention and revegetation methods are used The use of local seeds should also be promoted that improve the distribution of seeds and their for a second reason: seed collection or persistence in the soil. These innovations allow multiplication can provide an income support to obtain, quickly, a vegetal cover. for farms wishing to invest in this field. The environment protection is now at the Restoration of semi-natural grasslands with centre of the issues related with regional high biodiversity could offer the farmers a development.
