Temporal variability of water fluxes in a Pinus sylvestris forest patch in Mediterranean mountain conditions (Vallcebre research catchments, Catalan Pyrenees)
نویسندگان
چکیده
The Vallcebre research catchments are representative of Mediterranean mountain areas with spontaneous afforestation by Pinus sylvestris as a consequence of the abandonment of agriculture since the 1950s. In this context, transpiration, rainfall interception and internal fluxes in a Scots pine patch have been monitored. This paper presents the results obtained on temporal variability of these water fluxes. The result underline the importance of rainfall interception losses, representing about 24% of the bulk rainfall, and their high temporal variability depending on the meteorological conditions and on rainfall event characteristics. Soil water content has been found to be a limiting factor for tree transpiration during summer periods, even in the studied area where the annual rainfall exceeds the reference évapotranspiration.

The terms ∆soil and ∆snow can be ignored when evaluating big catchments on a yearly basis under a Mediterranean climate with dry summers. It is assumed that the soil and snow water storage are almost completely exhausted by the end of the hydrological year. The term ∆aquifers can also be neglected when the global water balance is not greatly affected by subterranean circulation. Equation 1 then...
متن کاملSpatiotemporal Variability in Tree Growth in the Central Pyrenees: Climatic and Site Influences
To understand how tree growth has responded to recent climate warming, an understanding of the tree–climate–site complex is necessary. To achieve this, radial growth variability among 204 trees established before 1850 was studied in relation to both climatic and site factors. Seventeen forest stands were sampled in the Spanish Central Pyrenees. Three species were studied: Pinus uncinata, Abies ...
متن کاملImpact of Drought on the Intra-Annual Growth of Pinus sylvestris L
Climatic scenarios for the Mediterranean Region forecast increasing frequency and intensity of drought events. We analyzed how Pinus sylvestris modifies its cambial phenology and intra-annual growth under enhanced drought conditions. For this purpose, a rainfall exclusion experiment was applied in 2012 to trees located in the lower elevation limit of a mountain forest in Central Spain. Prelimin...
متن کاملTranspiration of montane Pinus sylvestris L. and Quercus pubescens Willd. forest stands measured with sap flow sensors in NE Spain
Stand transpiration was measured during the 2003 and 2004 growing seasons using heat dissipation sap flow sensors in a Scots pine (Pinus sylvestris L.) and a pubescent oak (Quercus pubescens Willd.) forests located in a montane area of the Eastern Pyrenees (NE Spain). The first aim of the study was to assess the differences in quantitative estimates of transpiration (Ec) and the response to eva...
