By the end of the 19th and beginning of the 20th century new developments in agricultural technology caused an intensification of the agricultural practices. Species adapted to the diversity of structures or resources of high naturalistic value farmlands, like permanent pasture, cannot survive under increasingly high intensity agricultural management. The Italian MD n.30125 dated 22/12/2009 (Standard 4.1) defines, among the measures for the protection of permanent pasture and avoidance the deterioration of habitats, the prohibition to convert permanent pasture into arable crops and to till with the exception of agricultural practices related to the renewal and/or thickening of the sward and to the drainage water management. Permanent pastures biodiversity performs key ecological services and if correctly assembled in time and space can lead to agroecosystems capable of sponsoring their own soil fertility, crop protection and productivity. The vegetative cover of permanent pasture prevents soil erosion, replenishes ground water and controls flooding by enhancing infiltration and reducing runoff. The changes of land use or some practices change insect community and vegetation diversity. Physical disturbance of the soil caused by tillage increases risk of erosion and reduces the recycling of nutrients and proper balance between organic matter, soil organism and plant diversity. Is necessary a habitat preservation policy because after a change, even a return to past management would not completely re-establish the complex structure of habitats.
