20260812 04234000 1.0 TRUE Les prairies et pâturages secs sont des milieux particulièrement riches où une végétation et une faune typique se développent. Devant leur existence à une agriculture extensive, ils sont aujourd'hui menacés de disparaître.<br />En Suisse, près de 90 % des prairies et des pâturages secs ont disparu depuis la fin du XIXème siècle.<br />Conséquence de ce recul, les espèces qui peuplent ces habitats sont en situation précaire. Près de 40% des espèces végétales et 50% des espèces animales inféodées aux milieux secs figurent sur des listes rouges nationales et sont donc menacés.
