International audienceOften, the destruction of sown grasslands is linked to a decrease in productivity and/or a change in flora over time. These evolutions are rarely objectified and are the subject of two recent research-action projects in the Great West, in which observatories of young, well-established plots were monitored for 4 years (PERPeT project) and 5 years (PTD project). The monitoring focused on the annual biomass harvested and botanical composition, in order to determine how the grasslands age according to the initial sowing, the pedo-climate and the use practices of the plots. The synthesis of the main results allows us to conclude that "it is possible to age grasslands well", that their evolution is multifactorial with climat...
