4.1 General site character

Habitat class % Cover

Total Habitat Cover


Other Site Characteristics

Espacio esencialmente fluvial que comprende la confluencia de los ríos Segre y Noguera Ribagorçana. El espacio muestra la morfología fluvial de carácter dinámico de los ríos pirenaicos que penetran en la cubeta de desagüe de la Depresión Central. Los bosques de ribera más frecuentes son las alamedas y las saucedas, así como las poblaciones de alisos (Alnus glutinosa).

4.2 Quality and importance

Excelente representación de los sistemas fluviales de la Catalunya occidental

Los límites de este espacio han sido trazados de acuerdo con la cartografía topográfica y planimétrica de referencia, a escala 1:50.000, del Instituto Cartográfico de Catalunya, que es el instituto cartográfico oficial y competente de la Generalitat de Catalunya. Los mapas facilitados para formalizar la propuesta de este espacio y definir su delimitación, citados en más adelante en este formulario, tienen la misma precisión de detalles, y la misma calidad, que los mapas de la cartografía topográfica y planimétrica de referencia, a escala 1:50.000, que publica con carácter oficial el Instituto Cartográfico de Catalunya. Estos mapas son la referencia, si no se indica lo contrario, de los detalles de descripción planimétrica, topográfica y/o toponímica que se puedan dar en este formularioEste espacio está incluido en el 'Pla d'Espais d'Interès Natural' (PEIN), aprobado por el Decreto 328/1992 de la Generalitat de Catalunya. Su inclusión en el PEIN implica un grado de protección del lugar que no queda reflejado en el Apartado 5.1 del formulario, ya que la figura PEIN no está recogida en el mismo. La delimitación de este espacio tiene la finalidad de incluir en la red Natura 2000 únicamente el dominio público hidráulico, así como la vegetación de ribera (leñosa o no) y los herbazales húmedos no de siega, de acuerdo con la Cartografía de los Hábitats de Cataluña, elaborada en convenio entre la Generalitat de Catalunya y la Universidad de Barcelona.
