Abstract
En el presente trabajo se propone un itinerario hidrológico por cada una
de las cuatro Reservas Naturales de la provincia de Sevilla. Estos Espacios
Naturales Protegidos lo están por albergar lagunas someras, temporales y de
aguas salobres. Estas lagunas se encuentran ubicadas en la campiña del sur
de España, y constituyen ecosistemas muy frágiles y de alto valor ecológico
por ser muy escasos en Europa y estar sometidos a una alta presión por actividades
agrícolas en sus cuencas vertientes. En estos itinerarios se resalta
la existencia de hitos hidrológicos significativos -como los manantiales- y el
grado de alteración de cada una de las lagunas, algunas de las cuales están
parcial o totalmente drenadas con fines agrícolas. Se han incluido en algunos
de los casos propuestas de mejora como la construcción de puestos de
observación de aves o mejora en los accesos. Este artículo pretende contribuir
a la divulgación del Patrimonio Natural de la provincia de Sevilla y, en
particular, al de los humedales de campiña andaluces
The aim of this work is to propose four itineraries, one in each of the Nature Reserves of the province of Seville. These Protected Natural Areas host shallow, temporary and brackish-water playa-lakes. These playa-lakes are located in the countryside of southern Spain and they are fragile and scarce ecosystems with a high ecological value. Moreover, they are subjected to a high agricultural pressure in their watersheds. In these itineraries significant elements, such as springs, and the alteration degree of the playa- lakes, some of which are partially or completely drained for agricultural use, are highlighted. Some improvement proposals such as bird viewpoints or new accesses, that are private in some cases, have also been included. This paper aims to contribute to the dissemination of the Natural Heritage of Seville and, particularly, of the wetlands of Andalusia, often unknown by society. Furthermore, the improvement proposals are intended to facilitate accessibility
