Abstract: au sein desquelles on été choisies plus particulièrement trois stations, a conduit à prendre en compte l'ensemble du territoire où elles se situent, ainsi que son utilisation par les communautés usagères. Unité essentielèment agro-pastorale au XIXème siècle (de 1833 à 1914), ce territoire alors très ouvert, s'est progressivement fermé au cours du XXème siècle (1942 à aujourd'hui) par reboisement naturel, à partir des haies, des lisières de bois..., selon diverses modalités, en relation avec l'exode rural lié à… Show more

“…The rural depopulation of the 1960s also explains the pronounced landscape changes in the study area. Similarities with other studies (Lasanta-Martínez 1988;García-Ruiz and Lasanta-Martínez 1990;Mazars and Gers 1997;Moreira et al 2001) suggest that isolated and less productive fields were the first to be abandoned, followed by the more productive ones. On the other hand, the initiation of French mountain policy in the 1980s favored the installation of new cattle farmers and the common use of prescribed burning to control shrub encroachment.…”

“…However, during the last decades, socioeconomic globalization has induced profound transformations in rural areas (Barbero et al 1990;Debussche et al 1999;MacDonald et al 2000). Land abandonment has reduced the extent of open space and induced an expansion of woody vegetation, at least in the central Pyrenees (García-Ruiz et al 1996;Mazars and Gers 1997;Molinillo et al 1997), with repercussions for the disturbance regime and ecological diversity (Barbero et al 1990;Trabaud and Galtié 1996;Preiss et al 1997;Lloret et al 2002).…”
