Abstract Mediterranean mountain landscapes have high ecological and cultural values. However, since 1950, a large number of these landscapes have been subject to degradation as a consequence of land abandonment. Some regional administrations have enacted measures that favour the regeneration of pasturelands through scrubland clearing. The aim of this study was to evaluate the consequences of clearing and the regeneration of pasturelands on landscape structure and the recovery of extensive livestock in La Rioja. The results indicate that between 1986 and 2011 an area of 29,659 ha was cleared in the mountains of La Rioja, although 62·6% of this was cleared in the period 2000–2011. In 1956, the landscape was dominated by cultivated fields, but by 2001, much of the agricultural area had been abandoned and replaced by scrubland, natural woods and reforested areas. Furthermore, the landscape was more fragmented in 1956 than in 2001. The landscape structure varied following clearing, with a doubling in the number of patches and an increase in heterogeneity. The consequences of clearing have included an increase in the area of pastureland and the number of large animals. In addition, the number of farms has decreased, but their mean size has increased. Clearing is an appropriate way for spatial reorganization in marginal mountain areas. It does not require excessive investment but favours the reintegration of abandoned fields and an increase in pasturelands. The results of this study contribute to the debate about reclaiming mountain landscapes affected by human activities and subject to intense degradation processes.
