Aim To assess the spatial patterns of forest expansion (encroachment and densi- fication) for mountain pine (Pinus uncinata Ram.) during the last 50 years at a whole mountain range scale by the study of different topographic and socio- economic potential drivers in the current context of global change. Location The study area includes the whole distributional area of mountain pine in the Catalan Pyrenees (north-east Spain). This represents more than 80 munici- palities, covering a total area of 6018 km2 . Methods Forest cover was obtained by image reclassification of more than 200 pairs of aerial photographs taken in 1956 and 2006. Encroachment and densifica- tion were determined according to changes in forest cover, and were expressed as binary variables on a 150 ¥ 150mcell-size grid.We then used logistic regression to analyse the effects of several topographic and socio-economic variables on forest expansion. Results In the period analysed, mountain pine increased its surface coverage by 8898 ha (an increase of more than 16%).Mean canopy cover rose from 31.0% in 1956 to 55.6% in 2006. Most of the expansion was found on north-facing slopes and at low altitudes. Socio-economic factors arose as major factors in mountain pine expansion, as encroachment rates were higher in municipalities with greater population losses or weaker primary sector development. *Correspondence: Aitor Améztegui, Forest Technology Centre of Catalonia, Ctra.

E-mail: aitor.ameztegui@ctfc.cat Main conclusions The spatial patterns of mountain pine expansion showed a good match with the main patterns of land-use change in the Pyrenees, suggesting that land-use changes have played a more important role than climate in driving forest dynamics at a landscape scale over the period studied. Further studies on forest expansion at a regional scale should incorporate patterns of land-use changes to correctly interpret drivers of forest encroachment and densification
