The population barely perceives changes in vegetation that occur very quickly in subalpine regions. In recent decades, large areas have been invaded by woody plants, whilst demand for an open, attractive and readable landscape remains strong. The results of the modeling of vegetation dynamics carried out on the pasture of Larzey (VS) show a strong and rapid development of tree cover, accelerated by global warming, despite the maintenance of grazing pressure. This creates a loss in biodiversity as well as significant loss of attractiveness for the population. Thought should be engaged, on how maintaining landscapes with high environmental, aesthetic and social values, as well as on the means necessary to recognize and enhance landscape services provided by mountain agriculture.
