Geomorphic Processes above Timberline in the Spanish Pyrenees

Abstract: This paper prcsents a general account of geomorphic processes effective aboye timberline in the Spanish Pyrenees with emphasis on the central section of the range. Climatic and environmental factors are discussed in detail as well as thc geomorphic responses to lowering of the upper timberline, especially betwecn the sixteenth and ninetcenth centuries. During thi8 periad expansion of livestock grazing reduced the forest cover extensively and caused a substantiallowering of the lower altitudinallimit of perigla… Show more

“…The observations, however, refer to debris flows. García-Ruiz et al (1990) report that landslips do occur on the high meadows but these do not form debris flows and do not transfer much sediment into the river system. Hence simulation and observation are in general agreement for the high meadows in terms of debris flow occurrence.…”

“…Los bloques aradores se forman únicamente en ambientes periglaciares, bien sea por la existencia de permafrost o de hielo estacional (TUFNELL, 1972;CHATTOPADHYAY, 1983;BERTHLING et al, 2001a;2001b), si bien algunos autores consideran que, al menos en algunos casos, podrían estar asociados a procesos únicamente solifluidales (GARCÍA RUIZ et al, 1990;SERRANO CAÑADAS, 1998). De ahí que se puedan considerar indicadores de este tipo de ambientes, siempre que se pueda corroborar su actividad actual.…”

“…-El estudio de los sedimentos de llanuras aluviales y conos de deyección ha permitido observar posibles cambios en la dinámica fluvial y relacionar las áreas más alteradas por el hombre con ciertos rasgos de los sedimentos (MARTÍNEZ-CASTROVIEJO & GARCÍA- RUIZ, 1990;GÓMEZ-VILLAR, 1996).…”

“…La consecuencia fue el desplazamiento masivo de los suelos localizados en laderas de más de 25-30° de pendiente por medio de deslizatnientos planares (GARCÍA RUIZ et al, 1990) y la formación de terracillas de Festuca skia y F. Gautien). Fenómenos similares han podido constatarse en otras montat1as europeas durante los últimos siglos.…”
