Woody plant encroachment following grazing abandonment in the subalpine belt: a case study in northern Spain

et al. 2017

The montane and subalpine belts in European mountains were affected by intense land use/land cover changes during the 20th century. In the case of the subalpine belt, most European mountains were affected by complex deforestation processes from Neolithic times, leading to the expansion of summer grasslands to support grazing by transhumant sheep and goats flocks. This resulted in an altitudinal reduction of the tree line, and the occurrence of severe soil erosion and shallow landsliding. The intense livestock pressure over centuries explains why the landscape remained without major change until the middle of the 20th century. Since then, depopulation, land abandonment, and the disappearance of the transhumant system have resulted in a marked decline in livestock numbers, and subsequent encroachment of shrubs and trees in the subalpine belt. The Urbión Mountains (Iberian Range, northern Spain) provides one of the clearest examples in the Iberian Peninsula, where there was intense deforestation since the Neolithic period to enlarge the area of subalpine summer grasslands. The recent reversal of this situation in the last decades led to (i) a marked trend to dense forest, which resulted in an average 200 m altitudinal advance; and (ii) the spatial contraction of shrublands, which have been replaced by dense forest in the highest areas. Changes will continue in the future, possibly enhanced by global warming.

“…Another consequence is the reduction of subalpine grasslands (Lasanta and Vicente-Serrano, 2007), which has been related to the decline of grazing and the ascent of the upper tree line due to global warming (Sanjuán et al, 2013). The reduction of meadows and increase in scrubland in mountain areas is a widespread process in the Pyrenees (Camarero et al, 2015).…”

ABSTRACT. This study presents a joint analysis of the information from 195 field infiltration experiments, using double ring devices. The experiments were carried out in 20 contrasting types of land use, distributed across three geographic contexts (coast of NE Catalonia, an area of gentle relief in the centralPalabras clave: infiltración, ensayos con doble anillo, usos del suelo, cubierta vegetal, humedad del suelo, nordeste de España.

“…Throughout the 20th century, especially from 1940 to 1970, 70% of agricultural land was abandoned, and only the valley floors and some level areas in the mid-slope were still cultivated (Lasanta, 1988). Plant recolonisation in abandoned fields has enabled scrubland and forest expansion, and some areas were reforested with pines (Lasanta & Vicente-Serrano, 2007).…”

“…There are different aerial photographs (1977, 1981, 1990, ect. ) with higher resolution than the ones from 1957, but the natural revegetation process after land abandonment (75% of cultivated land was abandoned before 1950) complicate differentiate land patterns (Lasanta & Vicente-Serrano, 2007). Maps were made in five valleys in the Central Spanish Pyrenees ( Figure 1), including representative valleys of the Western (Aragón, Subordán and Estarrún rivers), Central (Alto Gállego) and Eastern (Ara and Bellós rivers) sectors.…”

Traditional Agrarian Landscape in the Mediterranean Mountains. A Regional and Local Factor Analysis in the Central Spanish Pyrenees

Development of rural areas needs information about sustainable use of the land. The main objective of this research is to study the spatial distribution pattern of different field types in the traditional agricultural landscape in the Central Spanish Pyrenees (flat fields, four different terrace fields, sloping field and shifting agriculture) related to different geoecological variables: slope, exposition, altitude, distance to the villages, rainfall (intensity and volume), lithology and demographic pressure. Agricultural land patterns were mapped in five valleys in the Central Pyrenees from aerial photographs (1957). These maps were digitised and implemented in a Geographic Information System on a scale 1:50,000. We determined the influence of different geoecological variables in the spatial distribution of land agricultural patterns at local and regional valley using statistical analysis. The results showed that the agricultural area occupied a large extension, despite physical environment limitations, extending even in marginal slopes, with little agricultural skills, creating a complex landscape with different field patterns. At the local scale (valley), slope and distance are the more influence variables to explain the spatial distribution of the different field types. At the regional scale, in the Western valleys, sloping fields and shifting agriculture predominate, while terraces dominate in the Eastern valleys. Distance to the village and rainfall intensity is the more determinant factors in the spatial distribution. Copyright © 2017 John Wiley & Sons, Ltd.
