Salada Farrachuela, a saline wetland in Tamarite de Litera, Spain

Abstract

This paper gives, for the first time, details of the vascular plants plus the soluble salts and other major components of their natural substrate in Salada Farrachuela, a hypersaline wetland located in the municipality of Tamarite, NE Spain. The wetland is situated on the outcropping evaporite-cored Barbastro Anticline, an area declared by the environmental authorities to be of community interest and part of the Natura 2000 network. This uncultivated and occasionally flooded wetland harbors plants able to withstand the conditions of their substrate whose upper layer (0–25 cm) has an average of 41% gypsum (CaSO4•2H2O), and 7.2 dS m−1 at 25 ºC electrical conductivity in 1:5 soil-to-water weight ratio (EC1:5) extracts. The EC1:5 value in the soil samples up to a depth of 2 m ranges from 6.23 to 7.95 dS m−1. At this depth, the average EC in the saturation extracts (ECe) is 37.0 dS m−1 , with sulfate being the most abundant ion (503 meq L−1), followed by magnesium (492 meq L−1), sodium (113 meq L−1), and chloride (41 meq L−1). Salinity, hydric conditions, and halophilous vegetation contrast distinctly with the surrounding nonsaline gypseous land and its gypsophilous vegetation. This article provides a baseline for future investigations of the ecology of this wetland in relation to salinity, and a reference for the monitoring needed to guarantee its conservation. Este artículo da por primera vez noticia de las plantas vasculares y de las sales solubles y otros componentes mayoritarios del suelo de la Salada Farrachuela, un humedal hipersalino situado en el municipio de Tamarite de Litera, provincia de Huesca, en el NE de España. El humedal se localiza en el afloramiento del núcleo evaporítico del anticlinal de Barbastro, un área declarada de interés comunitario incluida en la Red Natura 2000. Este humedal, inculto e inundado ocasionalmente, alberga plantas adaptadas a un suelo cuya capa superior (0-25 cm) tiene por término medio un 41% de yeso CaSO4•2H2O), 7.2 dS m−1 a 25 ºC de conductividad eléctrica en el extracto acuoso 1:5 en peso de suelo: agua (EC1:5). Para ese espesor de suelo, la conductividad eléctrica en extracto de saturación (ECe) a 25 ºC es 37.0 dS m−1, siendo el sulfato el ión más abundante (503 meq L−1) seguido del magnesio (492 meq L−1), sodio (113 meq L−1), y cloruro (41 meq L−1). La salinidad, las condiciones de humedad y la vegetación halófila contrastan fuertemente con las tierras circundantes, yesosas y no salinas. Este artículo puede ser un punto de partida para futuras investigaciones de la ecología del humedal en relación con la salinidad, y una referencia en el futuro seguimiento necesario para garantizar su conservación.
