Other Site Characteristics

El Espacio incluye el tramo del río Agadón que atraviesa, en dirección oeste, los términos municipales de Serradilla del Llano, La Atalaya y parte del de Zamarra (Salamanca); el tramo de río que discurre por este último municipio, desde su confluencia con el río de Las Vegas, recibe en algunos planos la denominación de río Badillo. Se trata de un río de la cuenca del Duero que sufre fuertes estiajes y a medida que discurre se va encajando en el terreno formando un pequeño cañón fluvial de gran interés como corredor ecológico. Mantiene algunos pequeños sotos bien conservados, poblados por alisos (Alnus glutinosa) y sauces (Salix spp.), alternando con zonas rocosas y sin apenas cubierta arbórea, sobre todo en su tramo final, donde se hacen patentes los efectos del reculaje del embalse del Águeda. El cauce linda con un mosaico de encinar, matorral mediterráneo, cultivos de secano, pastizales de media montaña e incluso pequeñas repoblaciones de pino.

4.2 Quality and importance

El Espacio presenta unas interesantes y valiosas formaciones de alisos (91E0*). Dentro del cauce, el régimen de crecidas-estiajes típico de los ríos mediterráneos propicia la existencia de una vegetación pionera anual característica de herbáceas de medio porte, muy frondosa, representativa del hábitat de ríos de orillas fangosas con vegetación de Chenopodion rubri p.p. y de Bidention p.p.(3270). Además, dentro del Espacio se concentran abundantes poblaciones de galápago leproso (Mauremys leprosa) y galápago europeo (Emys orbicularis) sin aparentes problemas de conservación. Entre la singular comunidad de peces existente destacan las poblaciones de calandino (Squalius alburnoides), endemismo ibérico adaptado a vivir en un amplio rango de cauces. Cabe destacar igualmente la presencia frecuente en el Espacio de la nutria (Lutra lutra).Entre las especies incluidas en el anexo IV de la Directiva destacan las poblaciones presentes de rana patilarga (Rana iberica).
